Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic block diagram showing a hardware configuration example of the information processing apparatus 10 according to the embodiment of the present invention.
The information processing apparatus 10 includes one or more devices and a memory, and constitutes a computer system. In the present embodiment, the device refers to hardware having a function of executing a process instructed by various instructions (commands), mainly a processor. Processors typically include arithmetic units, registers and peripheral circuits.
In the example shown in FIG. 1, the information processing device 10 includes a CPU (Central Processing Unit) 12, a memory 12 m, and a memory device 16. The CPU 12 is connected to each of the memory 12m and the memory device 16 so as to be able to input / output various data to each other according to a predetermined standard (for example, PCI (Peripheral Component interconnect) Express).

The CPU 12 is a processor mainly used as a host device (Host Device). A host device means a device that performs central processing in a computer system. The processor reads various programs from the programs stored in the memory device 16 in advance, and writes the read programs in the memory 12m (recording). The processor executes the processing indicated by the instructions described in various programs. In the present application, executing the process indicated by the instruction described in various programs may be referred to as executing the program, executing the program, or the like. Further, executing the process indicated by the instruction may be referred to as executing the instruction, executing the instruction, or the like.

The memory 12m includes, for example, a volatile main storage device such as a DRAM (Dynamic Random Access Memory), and is used as a work area for storing data used for processing in the CPU 12 or generated data. The memory 12m functions as a system memory.
The memory device 16 includes, for example, any auxiliary storage device such as a ROM (Read Only Memory), an HDD (Hard Disk Drive), or an SSD (Solid Disk Drive), or a set thereof, and various data can be stored in the information processing device 10. Remember available. The memory device 16 stores various programs such as an OS (Operating System), a library, a utility, and an application program, and various parameter sets used for executing them.

The number of devices included in the information processing apparatus 10 is not limited to one, and may be two or more. Devices are generally classified into host devices and accelerators. Some or all of the two or more devices may be accelerators. The accelerator is a device for controlling the processing by the host device and supporting the speeding up of the processing as a computer system. The type of device used as an accelerator is arbitrary. The device used as an accelerator is not limited to the CPU, but can be any of an image processing unit (GPU: Graphic Processing Unit), a vector engine (VE: Vector Engine), a deep learning accelerator (DLA), a quantum processor, and the like. , Or a combination thereof may be used.
In addition to the built-in memory, a dedicated main storage device may or may not be connected to each device. When the information processing apparatus 10 is provided with a memory other than the memory 12m, the memory 12m is not limited to its own part (memory 12m), and the position and size (information amount) of the data stored in the other memory. The management data indicating the above may be stored.

Further, the information processing apparatus 10 may include an operation unit (not shown) that receives an operation input and generates an operation signal for instructing an operation according to the received operation input. The information processing apparatus 10 is an input / output unit (not shown) for inputting or outputting various data with other devices according to a predetermined input / output standard (for example, PCI Express) or communication standard (for example, IEEE802.3). ) May be provided.

Next, a functional configuration example of the information processing apparatus 10 according to the present embodiment will be described. FIG. 2 is a schematic block diagram showing a functional configuration example of the information processing apparatus 10 according to the present embodiment. The CPU 12 executes a program described later and functions as an information processing device 10 including an execution management unit 22 and an execution processing unit 24.
The execution management unit 22 identifies the main program (Main Program) to be executed, and manages the execution of one or more various instructions described in the main program. The execution management unit 22 may specify either the main program stored in the memory 12 m in advance based on the operation signal input from the operation unit or the input / output unit, or the main program to be executed from the input / output unit. May be obtained. In the present application, the main program means a program including at least one preset call (reference) instruction of a subprogram, and is not necessarily limited to the highest-level program in a set of programs. The main program in the present application may be, for example, a program treated as a subprogram referred to in response to a call instruction from another program. The main program is typically an application program (user program) developed by an individual user.

In the following explanation, the case where the subprogram is a function program that mainly saves the output data as a return value at the end of execution is taken as an example, but it is not limited to this. The subprogram may be a subroutine that returns output data in another form or a subroutine that does not return output data. As another form, for example, there is a method of storing the output data as the operation result at the specified address. The output data can be referred to by using the address when the subsequent instruction of the main program or the subsequent function program is executed. Here, the function program may be called a kernel. The function program may be a program instructing predetermined element processing that performs various data processing. The element processing is not limited to the calculation of individual function values, but may be a series of calculation sets such as image recognition using a machine learning model and prediction of weather information using a physical model.

The execution management unit 22 sequentially executes the individual instructions described in the main program. That is, after the execution of a certain instruction is completed, the execution management unit 22 sequentially repeats the process of executing the next described instruction until there are no unexecuted instructions. When the repetition of one or more instructions is described in the main program, the execution management unit 22 repeats the execution of the instruction to be repeated according to the repetition condition. When the condition judgment is described in the main program, the execution management unit 22 determines whether or not the condition is satisfied, and if it is satisfied, executes the instruction to be executed in that case and is satisfied. If not, the instruction to be executed in that case is executed. However, the execution management unit 22 determines whether or not each instruction is an instruction indicating a call to a predetermined function program (hereinafter referred to as a call instruction). When the execution management unit 22 determines that the call command is a call command, the execution management unit 22 outputs (notifies) the call command to the execution processing unit 24. The call instruction includes a descriptor of input data to be processed in the process indicated by the function program (hereinafter, input data descriptor). The input data descriptor contains at least an address indicating the location of the input data. The input data descriptor may include the amount of information of the input data, the transfer method, any one of the data types, or a combination thereof.

After that, the execution management unit 22 inputs the execution device information indicating the execution device ED04 that executes the process indicated by the function program from the execution processing unit 24. The execution management unit 22 outputs the call instruction to the execution device specified by the input execution device information. The execution device ED04 is notified of the input data descriptor together with its function program by a call instruction. When the execution end notification (hereinafter referred to as the execution end notification) is input from the execution device ED04 that has executed the function program, the execution management unit 22 changes the instruction to be executed to the next instruction.

The call instruction may include an output data descriptor by the process instructed by the function program. If the call instruction contains an output data descriptor, the execution completion notification input from the execution device includes the output data descriptor. Therefore, the execution management unit 22 can detect the end of the process by inputting the execution completion notification including the output data descriptor from the execution device. The output data descriptor is a descriptor of the output data acquired by the process indicated by the function program. The output data descriptor contains at least an address indicating the location of the output data. The output data descriptor may include the amount of information of the output data, the transfer method, any one of the data types, or a combination thereof.

The execution management unit 22 executes the process instructed by the predetermined execution management program and exerts its function. The execution management program is included as a part of a predetermined software framework (Software Framework). In general, a software framework includes a function library consisting of one or more (usually, a plurality) subprograms indicating element processing for realizing various general functions. In the following description, the software framework is simply referred to as a framework.

Frameworks include, for example, OpenCV, TensorFlow, Keras, Tornado, and the like. Frameworks can often be used to develop application programs that describe instructions for calling function programs to become individual general functions. By using the framework, the burden on the development of the program for realizing the general function is avoided or reduced, which can contribute to the efficiency of the application program development. It was

However, the execution management unit 22 manages the execution of the subprogram belonging to the library of the framework in principle, but the function of the other subprogram (hereinafter referred to as the external program) cannot be called as it is. In this regard, in this embodiment, the designated program (blackbox kernel, FIG. 3) is included in the framework in advance. By including the external program information indicating the external program to be executed as the input data information for the specified program, the external program (for example, kernel B, FIG. 3) is called, and the predetermined processing instructed by the called external program is performed. Make it feasible.

In the following explanation, the framework library is called a standard library, and among the subprograms included in the standard library, the preset subprograms other than the specified program may be called the standard program. In addition, a library that is not included in the framework, that is, a library to which an external program belongs may be called an external library. Each library (that is, a standard library, an external library) may be configured as a DLL (Dynamic Link Library). DLL is a library including subprograms configured in a format that can be combined (dynamically linked) and executed when the main program is executed. In DLL, each subprogram is written in binary format. Each DLL is called not only by a specific main program but also by other main programs (reference), and can execute a predetermined process indicated by the called subprogram (shared).

The execution processing unit 24 specifies a function program instructed by a call instruction input from the execution management unit 22. The execution processing unit 24 starts execution of the specified function program. When the call instruction includes input data information, the execution processing unit 24 further specifies the input data indicated by the input data information. The execution processing unit 24 starts executing the processing indicated by the function program for the specified input data. The execution processing unit 24 generates an execution end notification when the processing is completed, and outputs the generated execution end notification to the execution management unit 22. When the call instruction includes output data information, the execution processing unit 24 identifies the output data indicated by the output data information among the various data acquired by the processing. The execution processing unit 24 outputs the specified output data to the execution management unit 22 in association with the execution end notification information.

When the function program instructed by the call instruction is a designated program (blackbox kernel), the execution processing unit 24 executes the designated program, input data acquisition unit 242, library load unit 244, and function address resolution unit. The functions of 246, the function calling unit 248, and the output data setting unit 250 are realized. Among them, the input data acquisition unit 242 and the output data setting unit 250 perform processing unique to the library, that is, common to the function programs belonging to the library.

The input data acquisition unit 242 acquires the input data information in the unique predetermined format by using the predetermined procedure peculiar to the predetermined framework with the call command. The input data information specified by the designated program includes external program information. The external program information may include information that identifies the external program, for example, a function name as the name of the external program. The external program information may include the name of the external library to which the external program belongs, that is, the library name. The input data acquisition unit 242 outputs the acquired input data information to the library load unit 244, the function address resolution unit 246, and the output data setting unit 250.

The library loading unit 244 specifies a library name indicated by input data information input from the input data acquisition unit 242, and among the libraries stored in the memory device 16 (FIG. 1) in advance, an external library having the specified library name. Is read. The library loading unit 244 stores (loads) the read external library in the memory 12m. The library loading unit 244 specifies a function address indicating a position on the storage area of each external program belonging to the external library stored in the memory 12m. The library loading unit 244 generates external program information indicating the correspondence between the function name and the specified function address for each external program stored in the memory 12m, and stores the generated external program information in the memory 12m. .. The function address may be expressed in a general-purpose format in advance. The general-purpose format may be, for example, a format according to the rules specified by the OS installed in the information processing apparatus 10.

The function address resolution unit 246 specifies the function name indicated by the input data information input from the input data acquisition unit 242, and determines the function address of the external program having the specified function name (address resolution). More specifically, the function address solving unit 246 refers to the external program information stored in the memory 12m in advance by the library loading unit 244, and determines the function address corresponding to the specified function name. The function address solving unit 246 outputs the function address information indicating the defined function address to the function calling unit 248.

The function calling unit 248 specifies the function address indicated by the function address information input from the function address solving unit 246, and starts executing the function program indicated by the specified function address. When the processing of the function program is completed, the function calling unit 248 outputs an execution end notification indicating the end to the output data setting unit 250.

When the execution end notification is input from the function call unit 248, the output data setting unit 250 sets at least the output data including the execution end notification, and outputs the set output data to the execution management unit 22. The output data setting unit 250 sets the output data indicated by the output data information input from the input data acquisition unit 242 among the various data acquired by the process started by the function call unit 248. The output data setting unit 250 includes the execution end notification in the set output data, and outputs the output data including the execution end notification to the execution management unit 22.

The functions of the input data acquisition unit 242 and the output data setting unit 250 and the format of the data to be handled may be unique to the framework. That is, when the execution processing unit 24 executes the standard program as the function program indicated by the call instruction, the execution processing unit 24 realizes the functions of the input data acquisition unit 242 and the output data setting unit 250, while the library load unit 244 and the function. The function of the address resolution unit 246 is omitted. The input data acquisition unit 242 specifies the input data indicated by the input data information included in the call command input from the execution management unit 22, and acquires the specified input data. The input data is associated with the acquired input data, and a calling instruction is output to the function calling unit 248. The function calling unit 248 refers to the standard function address information stored in the memory 12m in advance, and specifies the function address corresponding to the function name indicated by the calling instruction. The function caller 248 starts executing the standard program specified by the specified function address. The input data acquired in the process shown in the standard program is used. Here, the standard function address information is predetermined information indicating the correspondence between the function name and the function address, which is the name of each standard program. The function address may be described in a predetermined format unique to the framework (unique). The function address indicated by the standard function address information has a different format from the function address of the external program. This has been one of the reasons why the external program cannot be accessed as it is and the external program cannot be executed.

(Operation example)
Next, an operation example of the information processing apparatus 10 according to the present embodiment will be described. FIG. 3 is an explanatory diagram for explaining an operation example of the information processing apparatus 10 according to the present embodiment. FIG. 3 is an example of a case where a user program is provided as a main program to be executed. In the user program, execution of the three function programs kernel1, kernel8, and blackbox is instructed in that order. The function programs kernel1 and kernel8 are standard programs included in the framework library. In the user program, a call instruction indicating execution of each of the function programs kernel1 and kernel8 is described. The execution management unit 22 sequentially calls the function programs kernel1 and kernel8 from the framework library according to those call instructions, and causes the execution processing unit 24 to execute them.

On the other hand, in the user program, a call instruction indicating the designated program blackbox is described after the function programs kernel1 and kernel8. The function program kernelB is instructed as the input data information of the designated program blackbox. The function program kernelB is an external program included in the external library. The execution management unit 22 calls the designated program blackbox kernel from the library of the framework according to the call instruction indicating the designated program blackbox, and causes the execution processing unit 24 to execute the kernel. The execution processing unit 24 identifies the function program kernelB indicated by the input data information as the processing instructed by the blackbox kernel, and then the execution processing unit 24 loads at least the function program kernelB from the external library into the memory 12m. , Starts the execution of the loaded function program kernelB.

FIG. 4 is a diagram showing an example of the main program according to this embodiment. The main program exemplified in FIG. 4 is the extraction of the predicted value pred indicating the possibility of the region of interest from the output data data using the deep learning (DL) model as the user program to be processed, and the predicted value. It is instructed to repeatedly execute the process (simulation) to obtain the output data by performing arithmetic processing for each element area of the area of interest obtained based on the program with higher accuracy than other analysis areas.

In the first line of FIG. 4, data = init () indicates the initialization of the output data, that is, the process of determining the initial value in each element area in the analysis area.
In the second line, for ... indicates the repetition of the process instructed by the instruction ... described accompanying this statement.
In the fourth line, tp1 = fw. kernel. The conv (data) is a call instruction indicating that a convolution operation is performed on the output data data of the previous step according to the function program data in the framework, and the obtained operation result is defined as the output data mp1.

In the fifth line, tp2 = fw. kernel. According to the function program relu in the framework, relu (tmp1) calculates the function value of the normalized linear function (Rectified Linear Function) using the data tp1 as input data, and determines the obtained function value as the output data tpp2. It is a call instruction indicating that.
In the sixth line, pred = fw. kernel. softmax (tmp2) calculates the function value of the Softmax Function using the data tp2 as input data according to the function program softmax in the framework, and outputs the predicted value pred which is the obtained function value. It is a calling command indicating that it is defined as.

In the eighth line, data = fw. kernel. The blackbox (data, pred, "libsim.so", "dosim") is a function program included in the framework, and as input data to be processed according to the specified program blackbox, the output data data of the previous step and the predicted value pred. , External library libsim. It is a call instruction indicating that the output data tp3 obtained for so and the external program dosim is defined. By executing the specified program blackbox, the external library libsim. so is loaded, and the external program dosim is specified among the loaded external libraries. The specified external program dosim performs predetermined arithmetic processing (simulation) using the output data data of the previous step as input data with higher accuracy than other target areas for the important area obtained based on the predicted value pred. The process of calculating the output data of the current step is shown.
In the tenth line, data = fw. The run (data) is a call instruction indicating that the output data data of the previous step is updated to the output data data of the latest step obtained by executing the process instructed by for or less.
In FIG. 4, the symbol # indicates a comment line. Comment lines are mainly used to describe explanations of various instructions and parameters, and do not indicate any processing.

When the user program includes a call instruction for a standard program included in the framework library and does not include a call instruction for an external program, the execution management unit 22 indicates by those call instructions as in the prior art. It suffices to have the execution processing unit 24 execute the standard program to be executed. In the user program illustrated in FIG. 8, the execution of the two function programs kernel1 and kernel8 is instructed in that order. The function programs kernel1 and kernel8 are both standard programs included in the framework library.
However, in the user program exemplified in FIG. 9, the execution of the external program kernelB is instructed in addition to the function programs kernel1 and kernel8. The execution management unit 22 differs from the library of the framework to which the execution management unit 22 belongs in the processing and data format for each of the input data information and the output data information for the external program kernelB. Therefore, the location of the external program is not specified, and reading fails.

On the other hand, according to the present embodiment, when the subprogram instructed by the call instruction described in the main program is an external program, the location of the external program is specified by executing the specified program, and the specified external program is specified. It can be made feasible. Therefore, the development of the main program can be promoted by making it possible to execute the external program without modifying the framework other than including the designated program.

(Modification example)
Next, a modification of the present embodiment will be described. However, unless otherwise specified, the same configuration as that of the above embodiment shall be provided, and the description thereof shall be incorporated. In the following description, the differences from the above embodiments will be the main points.
The information processing apparatus 10 according to the present embodiment includes a plurality of devices, and the library of the framework may include a designated program in which any one of the plurality of devices is designated as an execution device. The execution management unit 22 causes the execution device to execute the designated program. Further, the execution management unit 22 may cause the execution device to execute an external program called by the designated program to exert the function of the execution processing unit 24.

FIG. 5 is a schematic block diagram showing a hardware configuration example of the information processing apparatus 10 according to this modification. In the example shown in FIG. 5, the information processing apparatus 10 includes a CPU 12, a GPU 14, and a memory device 16. The CPU 12, the GPU 14, and the memory device 16 are connected to each other so that various data can be input and output according to a predetermined standard. The memory device 16 can be referred to by either the CPU 12 or the GPU 14. A memory 12m and a memory 14m are connected to the CPU 12 and the GPU 14, respectively, so that various data can be input / output.
The CPU 12 functions as a module including an execution management unit 22 and an execution processing unit 24c. The GPU 14 functions as a module including an execution processing unit 24g. The

execution processing units

24c and 24g execute a standard program and an external program, respectively. Standard programs and external programs are stored in advance in the

memories

12m and 14m.

In order to instruct the execution of the designated program in which the execution device is specified, a call instruction including the device name of the execution device may be described. The execution management unit 22 causes the designated execution device to execute the designated program based on the call instruction to be processed, and causes it to function as either the

execution processing unit

24c or 24g.
FIG. 6 is a diagram showing an example of the main program according to this modification. The eighth line of FIG. 6 shows a call instruction indicating a designated program that specifies an execution device. Call command data = fw. kernel. Among blackbox_gpu (data, pred, "libsim.so", "dosim"), "blackbox_gpu" is a function name indicating a designated program in which GPU14 is designated as an execution device. Therefore, the designated program is executed as the execution processing unit 24g in the GPU 14, and the library "libsim.so" called by the execution of the designated program is loaded into the memory 14m. Further, the function program "dosim" called by the execution of the designated program is executed by the execution processing unit 24g. The execution processing unit 24g acquires the output data data and the predicted value pred of the previous step as the input data to be processed from the CPU 12. Then, the execution processing unit 24g outputs the output data data to the CPU 12 when the processing instructed by the function program “dosim” is completed.
By doing so, for example, the execution management unit 22 has an effect of allocating a device to a function program (in this example, “dosim” or the like) and improving the efficiency of data transfer according to the device on which the designated program is executed. Can be played.

In the examples shown in FIGS. 5 and 6, it is assumed that the information processing apparatus 10 includes the CPU 12 and the GPU 14, but the present invention is not limited to this. When the information processing apparatus 10 includes, for example, a vector engine as other devices, the vector engine may be designated as an execution device. Further, a plurality of designated programs may be included in the framework library, and different execution devices may be designated for each designated program. In the main program, the call instruction instructs the execution of each designated program. The input data information instructed by the call instruction may be instructed by a function program to be executed by the execution device. Further, the input data information may further indicate a library including the function program.
Further, the execution management unit 22 may determine whether the function program instructed for each call instruction described in the main program is a standard program or an external program. When the execution management unit 22 determines that the function program is an external program, the execution management unit 22 includes input data information indicating the function program (furthermore, a library including the function program may also be instructed), and a call instruction indicating the designated program. May be generated. The execution management unit 22 outputs the generated call instruction to the execution processing unit 24 in place of the call instruction to be processed indicating the function program. The execution processing unit 24 is instructed to execute the designated program by the call instruction input from the execution management unit 22. The execution management unit 22 can call and execute the function program by the above method. Therefore, the external program can be executed without explicitly describing the designated program in the main program.

Next, the minimum configuration of this embodiment will be described. FIG. 7 is a schematic block diagram illustrating the minimum configuration of the present embodiment.
As shown in FIG. 7, the information processing apparatus 10 according to the present embodiment includes an execution management unit 22 and an execution processing unit 24.
The execution management unit 22 identifies a subprogram described in the main program (for example, an application program) from a library including a plurality of subprograms (for example, a function program and a kernel), and is a specific subprogram that is the specified subprogram. Manages the execution status of the indicated predetermined process.
The execution processing unit 24 executes a predetermined process indicated by the specified specific program.
Then, the library includes a designated program (for example, a blackbox kernel) for executing a predetermined process indicated by an external program different from the plurality of subprograms.

According to this configuration, when the specified program is specified as a subprogram based on the main program, an external program different from the subprogram included in the library is specified as the process indicated by the specified program, and the specified external program is used. The indicated predetermined process can be executed. Therefore, the external program can be executed without modifying the framework related to the execution management unit 22 other than including the designated program in the library. Therefore, the development of the main program is promoted by effectively utilizing the existing framework.

Further, the execution processing unit 24 may define an external program based on the program name (for example, the function name) shown in the input data information for the specific program.
