PGI Workstation Complete 8.0.1 | 150 MB

PGPROF provides a way to visualize and diagnose the performance of the components of your program. Using tables and graphs, PGPROF associates execution time with the source code and instructions of your program, allowing you to see where and how execution time is spent. Through resource utilization data and compiler feedback information, PGPROF also provides features for helping you to understand why certain parts of your program have high execution times.
You can also use the PGPROF profiler to profile parallel programs, including multiprocess MPI programs, multi-threaded programs such as OpenMP programs, or a combination of both. PGPROF provides views of the performance data for analysis of MPI communication, multiprocess and multi-thread load balancing, and scalability.
Using the Common Compiler Feedback Format (CCFF), PGI compilers save information about how your program was optimized, or why a particular optimization was not made. PGPROF can extract this information and associate it with source code and other performance data, allowing you to view all of this information simultaneously. PGPROF also supports a feedbackonly mode, which allows you to browse Compiler Feedback in the absence of a performance profile.
Each performance profile depends on the resources of the system where it is run. PGPROF provides a summary of the processor(s) and operating system(s) used by the application during any given performance experiment.
