specific Embodiment approach 1
[0043] Specific implementation mode one: as figure 1 As shown, the present embodiment elaborates on the LLVM-based automatic performance prediction method for scientific computing programs of the present invention:
[0044] 1. Overall structure:
[0045] Realize the overall architecture diagram of the automatic performance prediction method for scientific computing programs based on LLVM, such as figure 1 shown;
[0046] For the performance model, our solution is not to give a formula and submit it to manual calculation like the traditional dynamic analysis method, because if the formula is too complicated, it is necessary to actually write a program to perform the calculation. So we skip the step of the formula, and then directly give a program, which can report the predicted program time when executed, and call this program DwarfCode. When building DwarfCode, I choose to build directly from the source code, retain the calculation code from the input to the number of cycle...
