Abstract: A parallelization assistant tool system to assist in parallelization of a computer program is disclosed. The system directs the execution of instrumented code of the computer program to collect performance statistics information relating to execution of loops within the computer program. The system provides a user interface for presenting to a programmer the performance statistics information collected for a loop within the computer program so that the programmer can prioritize efforts to parallelize the computer program. The system generates inlined source code of a loop by aggressively inlining functions substantially without regard to compilation performance, execution performance, or both. The system analyzes the inlined source code to determine the data-sharing attributes of the variables of the loop. The system may generate compiler directives to specify the data-sharing attributes of the variables.

Abstract: An optimization system to apply directives to a computer program without having to perform repeated front-end compilations of source code of the computer program is provided. In some embodiments, the optimization system performs a first compilation of the source code of the program to generate first front-end code and first back-end code of the computer program. The compilation includes a first front-end compilation and a first back-end compilation. The optimization system identifies a compiler directive to apply to a location within the first front-end code. The optimization system then performs a second back-end compilation of the first front-end code factoring in the compiler directive to generate second back-end code affected by the compiler directive.
