Description
Technical Field
The invention relates to the technical field of computers, in particular to a compiling option tuning method, a compiling option tuning device, a processor chip and a server.
Background
In the ecological development work of a Central Processing Unit (CPU), the work of optimizing compiling option parameters for various programs is involved. Including HPC (High Performance Computing), SPEC (Standard Performance Evaluation Corporation) CPU, FFTW (fast Fourier Transform in the West, Standard C language suite of fast Computing discrete Fourier transforms), and the like. Taking a SPEC CPU as an example, the SPEC CPU2017 is a set of CPU subsystem testing tools, and includes 43 tests of 4 kinds, including a SPEC speed 2017 integrating, a SPEC speed 2017 Floating Point, and a SPEC rate 2017 integrating and a SPEC rate 2017 Floating Point, which are performance tests for testing Integer speed and Floating Point operation speed. The processor, memory subsystem and compiler used in the SPEC CPU2017 test system all affect the final test performance. The SPEC CPU provides source code and allows the test user some compilation optimization. The compiler, as one of the important influencing factors, needs to optimally compile options on different test software compared with other compilers while continuously exploring the optimal compiling options of different compilers for the processor.
The source code scale of most programs to be called is huge, the hot-point function is not unique during operation, the execution mode is complex, and the input set is various. Meanwhile, the number of optimization options of the Compiler is large, and if all the compilation options are arranged and combined for a certain program, taking GCC (GNU Compiler Collection) as an example, the combination mode thereof may exceed 10800+The workload of manual referencing is enormous, wherein the GNU compiler suite includes C, C + +, Objective-C, Fortran, Java, Ada, and Go language front-ends, as well as libraries of these languages. In actual work, when compiling option parameter adjustment work is performed on a program, parameter adjustment work on the whole program is often involved. However, in the existing iterative tuning framework, the thermal function inside the program needs to be objectively and accurately packaged, and then further tuning is performed. The optimal parameter options analyzed for the encapsulated hotspot functions cannot guarantee the same optimization effect in the original program. In addition, the interface realized by the framework at present is simpler, only single-file source code parameter tuning is supported, and the test evaluation module can not support a more complex program well. The actual parameter tuning requirement is that a certain application program includes a plurality of operation subsets, and the operation parameters of each subroutine are different, and the respective hotspot functions are also different. At present, only automatic iterative parameter adjustment can be carried out on some extracted hotspot functions, and a set of integral compiling option optimization mode cannot be provided for each program. When the compiling option is optimized, if only part is selectedAnd a single file is optimized, and some optimization points are missed. Currently existing compilers provide optimization techniques for inter-procedural analysis and inter-procedural optimization that can globally optimize an entire program, rather than just within a single file, a single function, or a single code segment. Inter-process optimization can reduce inter-process recalculation, inefficient access to memory, and simplify iterative processes. Inter-process optimization may also rearrange the order of the code to optimize memory allocation and locality. In the process of actually calling the program, the compiler combines the compiling option optimized in the process with other compiling options, and can greatly improve the performance of the program. At present, only internal automatic parameter tuning optimization is supported for single files and single module code segments, and the effect of optimizing options such as inter-process tuning cannot be measured.
