Description

  The present invention relates to an arithmetic processing system including a user program system that executes a user program and a library program system that executes a library program used in the user program.

  Conventionally, a general-purpose numerical calculation library has been widely used when performing complicated and enormous operations such as scientific and technical calculations. A general-purpose numerical calculation library is a collection of subroutines of numerical calculation methods such as solving simultaneous linear equations, obtaining eigenvalues of matrices, performing spline interpolation, and solving differential equations.

  The calculation using the numerical calculation library is basically realized by an arithmetic processing system including a user program system in which a user program generated and used by a user is executed and a library program system in which the library program is executed. The The user uses the library program by including an instruction related to the execution of the library program in the user program.

  As described above, by using the numerical calculation library, the user does not need to create a complicated numerical analysis program himself. Therefore, it is possible to reduce the user's programming burden when performing scientific and technical calculations.

Next, a case where a simultaneous linear equation Ax = b is solved using a conventional arithmetic processing system will be described. In this case, the user program has the following instruction sequence.
REAL * 8 A (LDA, N), B (N)
(Data generation)
Calculation: Library call
CALL LU (LDA, N, A, IERR)
CALL SOLVE (LDA, N, A, B, IERR)
(Use of results)
END
Here, A is a matrix stored in the two-dimensional array A, and b is a vector stored in the one-dimensional array B.

  As described above, the user program designates data for each execution instruction of the library program. In other words, the user program must be responsible for the selection of the library program, the order of use, the selection of the data format, and the management of data such as intermediate results.

  When a library program in the library program system is improved or newly added, the user of the user program needs to change the content of the user program in consideration of this.

  In addition, the execution instruction of the library program includes specification of the data format, so if you want to change the input value, not only change the input value but also the execution instruction itself according to the data format Need to be changed.

  Therefore, an arithmetic processing system and an arithmetic method are disclosed that allow a user of a user program to use the library program more easily without being aware of specific processing in the library program system (Patent Document 4). reference).

  An outline of the arithmetic processing system disclosed in Patent Document 4 will be described with reference to FIG.

  The arithmetic processing unit 132 performs arithmetic processing of the library program. The arithmetic processing unit 132 includes a library program execution unit 142 and a transfer control unit 141.

  The library program execution unit 142 reads and executes the library program stored in the storage unit 133. When the user program being executed in the user program system 102 uses processing performed by the library program system 103, the transfer control unit 141 responds to a request from the user program system 102 in response to a request from the user program system 102.

  The storage unit 33 includes a library program storage unit 33A, a numerical data storage unit 33B, and an operation result data storage unit 33C. The library program storage unit 33A is an area for storing a library program executed by the arithmetic processing unit 32. The numerical data storage unit 33B is an area for storing the numerical data received by the numerical data transfer unit 41A and its data format. The calculation result data storage unit 33C is an area for storing the execution result of the library program by the library program execution unit 42. In actual use of the memory, the numerical data storage unit 33B and the calculation result data storage unit 33C are stored in the storage unit 33 as variables and arrays without being distinguished from each other. In addition, variables as intermediate data temporarily used in library program operations, management information indicating a directory structure for numerical data, and the like are also stored in the storage unit 33.

  Next, an operation example in the arithmetic processing system 101 will be described. Here, the user program in the user program system 102 includes an instruction to solve the simultaneous linear equation Ax = b, and the calculation of the simultaneous linear equation Ax = b is performed in the library program system 103. I will explain.

  Here, A is a coefficient matrix, and is assumed to be stored in a double-precision real type two-dimensional array. Also, b is a vector and is stored in a one-dimensional array of double precision real numbers. Further, x is a solution vector, and is stored in a one-dimensional array of double precision real type. The coefficient matrix A and the vector b are generated by the user program execution unit 121 in the execution process of the user program, and are stored as the array A1 and the array b1 in the numerical data storage unit 114B.

First, it is assumed that the user program is executed based on an instruction input from the user, and the user program execution unit 121 executes the next statement in the user program.
SILC_PUT ('A', & A1)
SILC_PUT ('b', & b1)
The above statement indicates an instruction to transmit the array A1 storing the coefficient matrix A and the array b1 storing the vector b to the library program system 103. When the above statement is executed by the user program execution unit 121, the numerical data transfer unit 122A controls the transfer processing unit 112 to transfer the array A1 and the array b1 to the library program system 103. As a result, the array A1 and the array b1 are transferred to the library program system 103 by the transfer processing unit 112. In the library program system 103, the numerical data receiving unit 141A receives the array A1 and the array b1, and stores them in the numerical data storage unit 133B as a coefficient matrix A and a vector b.

Next, it is assumed that the user program execution unit 121 executes the next statement in the user program.
SILC_EXEC ('x = A \ b')
The above statement indicates an instruction that instructs the library program system 103 to solve the simultaneous linear equation Ax = b as calculation request information. By this instruction, an operation is executed in the library program system 3.

Thereafter, the user program execution unit 121 executes the next statement in the user program.
SILC_GET (& x, 'x')
The above statement indicates an instruction for receiving the solution vector x as the operation result from the library program system 103.

  When the above statement is executed, the calculation result receiving unit 122C controls the transfer processing unit 112 to transfer the statement as result request information to the library program system 103. As a result, the result request information is transferred to the library program system 103 by the transfer processing unit 112. When the calculation result receiving unit 122C receives the calculation result data from the library program system 103, the calculation result data storage unit 114C stores the solution vector x as the calculation result data. Thereby, the calculation using the library program system 103 is completed.

  As described above, according to the arithmetic processing system disclosed in Patent Literature 4, input value information transfer processing, calculation content information transfer processing, and calculation result transfer processing are performed separately. The program can be configured in a state where instructions related to each process are separated from each other. Therefore, since the user program can be subdivided, it is possible to change the input value, change the calculation content, and the like more easily.

  Furthermore, according to the above arithmetic processing system, the user program system only has to transfer a character string representing the mathematical arithmetic expression itself to the library program system, and therefore consider how the arithmetic expression should be solved. There is no need to do.

Furthermore, according to the arithmetic processing system, since the user program system does not need to be involved in the arithmetic operation executed in the library program system, it is possible to reduce the size of the user program in the user program system, It is also possible to reduce the memory usage in the user program system.

It becomes possible.

  Furthermore, the arithmetic processing system according to the present invention may be configured such that, in the above-described configuration, the calculation request means transfers a character string representing a mathematical arithmetic expression itself as the calculation request information.

  According to the above configuration, the user program system only has to transfer a character string representing the mathematical arithmetic expression itself to the library program system. There is no need to consider whether to solve the equation. Therefore, the user of the user program can describe programming for performing calculations only by considering general mathematical arithmetic expressions.

  Furthermore, the arithmetic processing system according to the present invention may be configured such that, in the above configuration, the user program system and the library program system operate on the same computer.

  According to said structure, the above arithmetic processing systems are realizable by building a user program system and a library program system in one computer. Note that one computer may include a plurality of arithmetic processing devices (for example, CPUs) and share a memory.

  Furthermore, the arithmetic processing system according to the present invention is the above configuration, wherein the user program system operates on the first computer, and the library program system is connected to the first computer in another computer. It may be configured to operate.

(Processing flow in the arithmetic processing system)
Next, the flow of processing in the above-described arithmetic processing system 1 will be described below with reference to FIGS. FIG. 2 is a flowchart showing the flow of processing in the user program system 2, and FIG. 3 is a flowchart showing the flow of processing in the library program system 3.

(Processing flow in user program system)
First, the flow of processing in the user program system 2 will be described with reference to FIG. First, in step 1 (hereinafter referred to as S1), in the user program system 2, the user program execution unit 21 starts executing the user program. That is, for example, when the input / output unit 11 receives an instruction to execute a predetermined user program from the user, this information is transmitted to the user program execution unit 21. Then, the user program execution unit 21 reads the designated user program from the user program storage unit 14A of the storage unit 14, and starts executing the user program. Then, the interpreter unit 22 reads the user program and analyzes the character string described in the user program by a general method.

  When the arithmetic processing / control processing extracting unit 22A detects the arithmetic character string (YES in S2), the detected arithmetic character string transfers the numerical data and its data format to the library program system 3. (S3: YES), the numerical data transfer unit 23A controls the transfer processing unit 12 to transfer the numerical data and information related to the data format to the library program system 3. To do. The numerical data and information related to the data format may be input from the user by the input / output unit 11 or may be generated by a user program being executed. Thereby, the numerical data and information on the data format are transferred to the library program system 3 by the transfer processing unit 12 (S4). The numerical data transfer unit 23A stores the transferred numerical data and information related to the data format in the numerical data storage unit 14B of the storage unit 14.

  If the detected calculation character string indicates that the library program system 3 performs the calculation process (YES in S5), the calculation request unit 23B provides calculation request information indicating the calculation request content. The transfer processing unit 12 is controlled to transfer to the library program system 3. This calculation request information may be input from the user by the input / output unit 11 or may be generated by a user program being executed. Thereby, the calculation request information is transferred to the library program system 3 by the transfer processing unit 12 (S6).

  If the detected operation character string indicates that the result of operation processing performed in the library program system 3 is requested (YES in S7), the operation result receiving unit 23C receives the result request information. Is transferred to the library program system 3. In addition, you may request | require transfer of the numerical data stored in the numerical data storage part 33B which was only transferred and not calculated. The result request information may be input from the user by the input / output unit 11 or may be generated by a user program being executed. As a result, the result request information is transferred to the library program system 3 by the transfer processing unit 12. Thereafter, when an operation result is received from the library program system 3 by the transfer processing unit 12, the operation result receiving unit 23C stores the received operation result in the operation result data storage unit 14C in the storage unit 14 (S8).

  Next, when the arithmetic processing / control processing extracting unit 22A detects a control character string (YES in S9), the control processing unit 22B does not request the processing, and the control processing unit 22B detects the control character string. Control processing (conditional branching, iteration, etc.) according to is executed (S10).

  Next, when the input / output process extraction unit 22C detects an input / output character string (YES in S11), the detected input / output character string indicates an input process for reading data such as a matrix or a vector from a file. (YES in S12), the detected input / output character string is converted into a code that can be handled by the numerical data transfer unit 23A (S13), and then the numerical data transfer unit 23A converts the numerical data and its data format. The transfer processing unit 12 is controlled so as to transfer the information regarding to the library program system 3.

  As a result, information relating to input data such as a matrix or a vector is transferred to the library program system 3 by the transfer processing unit 12 (S14). The numerical data transfer unit 23A stores the transferred numerical data and information related to the data format in the numerical data storage unit 14B of the storage unit 14.

  On the other hand, when the detected input / output character string indicates a process of storing data such as a matrix or a vector as a result of the operation (YES in S15), the detected input / output character string is The code is converted into a code that can be handled by the calculation result receiving unit 23C (S16), and then the calculation result receiving unit 23C controls the transfer processing unit 12 to transfer the result request information to the library program system 3. In addition, you may request | require transfer of the numerical data stored in the numerical data storage part 33B which was only transferred and not calculated.

  As a result, the result request information is transferred to the library program system 3 by the transfer processing unit 12. Thereafter, when the operation result is received by the transfer processing unit 12 from the library program system 3, the operation result receiving unit 23C stores the received operation result in the operation result data storage unit 14C in the storage unit 14 (S17). The received calculation result may be transferred to the input / output unit 11 via the user program execution unit 21 and displayed / output to the user.

  If NO in any of the above S2, S9, and S11, the user program execution unit 21 performs user-defined processing, that is, other processing in the user program (S18). In S19, the user program execution unit 21 determines whether or not the execution of the user program has been completed. If the execution of the user program has not been completed (NO in S18), the process returns to S2. On the other hand, when it is determined that the execution of the user program has been completed (YES in S18), the processing of the user program ends.

  Note that the processes of S2, S9, and S11 are not limited to being performed in the above order, and may be performed in any order. That is, the processes of S4 to S8, S10, S13 and S14, S16 and S17 may be performed in the order in which the corresponding code is executed.

  Since the processing in the user program system 2 proceeds as described above, the processing in the user program system 2 proceeds asynchronously with the processing in the library program system 3.

(Processing flow in the library program system)
Next, the flow of processing in the library program system 3 will be described with reference to FIG. First, in S <b> 21, the numerical data receiving unit 41 </ b> A determines whether or not numerical data and information related to the data format have been received from the user program system 2 via the transfer processing unit 31. If it is determined that the numerical data and the information related to the data format have been received (YES in S21), the numerical data receiving unit 41A displays the received numerical data and the information related to the data format in the storage unit 33. The data is stored in the storage unit 33B (S22).

  Next, the calculation method determination unit 41B determines whether or not calculation request information has been received from the user program system 2 via the transfer processing unit 31 (S23). If it is determined that the calculation request information has been received (YES in S23), the calculation method determination unit 41B analyzes the received calculation request information, thereby determining the type of library program to be used and its execution order. Is performed (S24).

  Next, the library program execution unit 42 executes the calculation by the library program based on the type of library program determined by the calculation method determination unit 41B and the execution order thereof (S25). Here, the library program execution unit 42 reads out a necessary library program from the library program storage unit 33A in the storage unit 33, and relates to numerical data as an input value from the numerical data storage unit 33B in the storage unit 33 and its data format. Read the information and execute the calculation. Thereafter, the library program execution unit 42 stores the calculation result data in the calculation result data storage unit 33C in the storage unit 33 (S26).

  In addition, the calculation result transmission unit 41C determines whether or not the calculation result transmission request is received from the user program system 2 via the transfer processing unit 31 (S27). If it is determined that the calculation result transmission request has been received (YES in S27), the calculation result transmission unit 41C reads the calculation result data from the calculation result data storage unit 33C in the storage unit 33 and transfers it. Control to transmit from the processing unit 31 to the user program system 2 is performed. Thereby, the calculation result is transmitted from the library program system 3 to the user program system 2 (S28). When the transmission request is for the numerical data stored in the numerical data storage unit 33B, the calculation result transmission unit 41C reads the numerical data and its data format from the numerical data storage unit 33B in the storage unit 33, and transfers this. Control that is transmitted from the processing unit 31 to the user program system 2 may be performed.

  If NO in any of the above S21, S23, and S27, the process returns to S21.

  Note that the processing of S21, S23, and S27 is not limited to being performed in the above order, and may be performed in any order. That is, the processing of S22, S24 to S26, and S28 may be performed in the order in which the corresponding code is executed.

  Since the processing in the library program system 3 proceeds as described above, the processing in the library program system 3 proceeds asynchronously with the processing in the user program system 2.

(System configuration example 1)
Next, a specific configuration example of the arithmetic processing system 1 will be described with reference to FIG. In the system configuration example 1, as shown in FIG. 4, both the user program system 2 and the library program system 3 are executed in one computer 1A.

  The computer 1A is generally equipped with a CPU (Central Processing Unit) as arithmetic means, a RAM (Random Access Memory) as main storage means, a ROM (Read Only Memory) as a nonvolatile storage device, a hard disk, and the like. It is a computer. Each functional block of the control unit 13 in the user program system 2 and each functional block of the control unit 32 in the library program system 3 are realized by the CPU reading the corresponding program from the hard disk or the like into the RAM and executing it. . The storage unit 14 is realized by a RAM, a hard disk, and the like.

  Further, the transfer processing unit 12 in the user program system 2 and the transfer processing unit 31 in the library program system 3 perform data transfer processing between the program by the control unit 13 and the program by the control unit 32, that is, inter-process communication. I do. The input / output unit 11 is realized by an input unit such as a keyboard and a mouse provided in the computer 1A, a display as a display unit, a printer as a printing unit, and the like.

  Note that the computer 1A may have a plurality of processors and be capable of performing parallel operations.

(Specific operation example in system configuration example 1)
Next, a specific operation example in the system configuration example 1 will be described. The operation example here is as follows. The user program in the user program system 2 includes an instruction to solve the simultaneous linear equation Ax = b by the CG (Conjugate Gradient) method, and the operation of the simultaneous linear equation Ax = b is performed in the library program system 3. Is called. More specifically, the coefficient matrix A is stored in the first matrix data file, and the vector b is similarly stored in the second matrix data file. The solution vector x of the simultaneous linear equations Ax = b is stored in the third matrix data file. The storage format of the first matrix data file, the second matrix data file, and the third matrix data file is, for example, the MatrixMarket format, but is not limited thereto.

  The flow of processing in the above operation example is as follows. First, the control unit 32 in the library program system 3 is set to an operable state. Next, the control unit 13 in the user program system 2 starts executing a specific user program based on an instruction input from the user.

  Thereafter, in the execution process of the user program, numerical data used as an input value for the arithmetic processing and its data format are generated. In this operation example, the coefficient matrix A and the vector b are generated as numerical data and its data format. The generated coefficient matrix A and vector b are stored as a matrix data file A and a matrix data file B in the numerical data storage unit 14B.

Thereafter, the input / output processing extraction unit 22C of the interpreter unit 22 that has read the user program extracts the next statement from the user program.
load “A”, A
load “B”, b
The above statement shows an input process of reading a matrix data file A in which a coefficient matrix A is stored and a matrix data file B in which a vector b is stored. The instruction “load” is not particularly limited to this character string, and may be indicated by another character string.

  When the above statement is extracted by the input / output processing extraction unit 22C, the input / output processing unit 22D converts the read matrix data file A and matrix data file B into numerical data and data format that the transfer control unit 23 can process. The converted data is transferred to the transfer control unit 23.

  Then, the numerical data transfer unit 23A controls the transfer processing unit 12 to transfer the numerical data transferred from the input / output processing unit 22D and its data format to the library program system 3. Thereby, the matrix data file A and the matrix data file B are transferred to the library program system 3 by the transfer processing unit 12.

  In the library program system 3, the numerical data receiving unit 41A receives the matrix data file A and the matrix data file B, and stores them in the numerical data storage unit 33B as a coefficient matrix A and a vector b.

  Next, when the arithmetic processing / control processing extracting unit 22A of the interpreter unit 22 extracts the arithmetic character string indicated by the four arithmetic operations in the user program, the transfer control unit 23 calculates the arithmetic character string based on the extracted arithmetic character string. Instructs the transfer of numerical data and computation content information.

  Then, the numerical data transfer unit 23A and the calculation requesting unit 23B transfer the numerical data transferred from the calculation processing / control processing extraction unit 22A and the information of the calculation request contents to the library program system 3. 12 is controlled. As a result, the numerical data constituting the arithmetic processing and the contents of the arithmetic request are transferred to the library program system 3 by the transfer processing unit 12.

  In the library program system 3, the calculation method determination unit 41B receives the calculation request content and analyzes the received calculation request content information to determine the type of library program to be used and its execution order. Perform the process. Specifically, the calculation method determination unit 41B performs LU decomposition processing, forward / backward substitution processing, and the like based on the received calculation request content. Then, the calculation method determination unit 41B performs, for example, a process of assigning A1 (actually A is copied to A1) obtained by converting the defined A into a form suitable for the program, or assigning x and IP as intermediate variables. Do. A1, IP, and x are variables used only in the library program system 3. Then, the library program execution unit 42 executes the library program based on the calculation determined by the calculation method determination unit 41B, and derives a solution x. The derived solution is stored as operation result data in the operation result data storage unit 33C.

  Next, when the arithmetic processing / control processing extracting unit 22A of the interpreter unit 22 extracts a control character string indicating a conditional branch, repetition, etc. in the user program, the extracted control character string is sent to the transfer control unit 23. The contents of the control process are transferred to the control processing unit 22B. And control processing part 22B performs control processing according to the contents of the above-mentioned control processing.

For example, the arithmetic processing / control processing extracting unit 22A of the interpreter unit 22 extracts the next statement from the user program.
if (cond_expr1) {
stmt1;
} else if (cond_expr2) [
stmt2;
} else {
stmt3;
}
The above statement shows the conditional branch control process. Here, cond_expr1 and cond_expr2 are assumed to represent conditional expressions composed of comparison operators. Also, stmt1, stmt2, and stmt3 are arbitrary character strings. With the above statement, the control processing unit 22B executes 1) stmt1 when the conditional expression of cond_expr1 is satisfied, and 2) the conditional expression of cond_expr1 is not satisfied and the conditional expression of cond_expr2 is satisfied If the conditional expression of cond_expr1 is not satisfied and the conditional expression of cond_expr2 is not satisfied, stmt3 is executed. The control character string “if” is not particularly limited to this character string, and this control may be indicated by another character string.

For example, the arithmetic processing / control processing extracting unit 22A of the interpreter unit 22 extracts the next statement from the user program.
where (cond_expr) {
stmt;
}
The above statement shows the iterative control process. Here, cond_expr represents a conditional expression composed of comparison operators. Stmt is an arbitrary character string. With the above statement, the control processing unit 22B executes stmt as long as the cond_expr conditional expression is satisfied.

Further, the arithmetic processing / control processing extracting unit 22A of the interpreter unit 22 may extract the next statement from the user program.
continue
With the above statement, the control processing unit 22B continues the repetitive control processing.

Further, the arithmetic processing / control processing extracting unit 22A of the interpreter unit 22 may extract the next statement from the user program.
break
With the above statement, the control processing unit 22B interrupts the repetitive control processing.

  The control character strings “while”, “break”, and “continue” are not particularly limited to this character string, and this control may be indicated by other character strings.

Next, the input / output processing extraction unit 22C of the interpreter unit 22 extracts the next statement from the user program.
save “X”, x
The above statement indicates an instruction for receiving a solution x as a calculation result from the library program system 3 and storing the solution x in the matrix data file X. Note that the instruction “save” is not particularly limited to this character string, and may be indicated by another character string.

Note that the input / output processing extraction unit 22C of the interpreter unit 22 may extract the following statement.
pprint a
The above statement indicates an instruction for receiving the value of the expression a as the operation result from the library program system 3. The instruction “pprint” is not particularly limited to this character string, and may be indicated by another character string. The received value may be displayed / output on the input / output unit 11.

  When the above statement is extracted by the input / output processing extraction unit 22C, the input / output processing unit 22D converts the instruction into a command that can be processed by the transfer control unit 23, and transfers the converted instruction to the transfer control unit 23. To do.

  Then, the calculation result receiving unit 23C controls the transfer processing unit 12 so as to transfer the converted instruction as the result request information to the library program system 3. As a result, the result request information is transferred to the library program system 3 by the transfer processing unit 12.

  In the library program system 3, the calculation result transmission unit 41C receives the result request information, and reads the calculation result data requested by the result request information from the calculation result data storage unit 33C. The calculation result transmission unit 41 </ b> C performs control to transmit the read calculation result data from the transfer processing unit 31 to the user program system 2. As a result, the calculation result is transmitted from the library program system 3 to the user program system 2. If the calculation is not completed in the library program system 3 when the result request information is received, the calculation result data is not transmitted until the calculation is completed.

  In the user program system 2, when the calculation result receiving unit 23C receives the calculation result data from the library program system 3, the calculation result data 23 is stored in the calculation result data storage unit 14C as a matrix data file. Thereby, the calculation using the library program system 3 is completed.

  Thereafter, when the execution of the user program is completed, the data stored in the numerical data storage unit 33B and the operation result data storage unit 33C are cleared in the library program system 3, and the operation of the control unit 32 is stopped. Note that the clearing of data in the library program system 3 and the stop of the operation in the control unit 32 may be performed when the user program no longer needs to use the library program system 3.

  A new user program may be executed in the user program system 2. At this time, data may be transferred from the previous user program to the new user program via the library program system 3.
