PGPROF can profile parallel programs, including multiprocess MPI programs This chapter introduces the PGPROF profiler. 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. The PGPROF Graphical User Interface (GUI) is invoked using the command pgprof. This chapter describes how to use the profiler with the GUI. Chapter 2 The PGPROF Profiler describes the PGPROF Profiler. This tool analyzes data generated during execution of specially compiled C, C++, F77, F9x and HPF programs. Users seeking additional information, such as how to produce other kinds of profiling output, may refer to the official PGPROF Profiler Guide. Use the PGPROF profiler to profile parallel programs, including multiprocess MPI programs, multi-threaded OpenMP programs, or a combination of both. Среди них есть как проприетарные (например, Intel Thread Profiler или PGPROF) так и open source проекты (например, ompP). It also includes a graphical profiler (PGPROF) and a debugger (PGDBG). This package can also be used with the VAMPIR profiler and with the TotalView parallel debugger. The Portland Group, Inc. Please see http://www.pgroup.com/. PGPROF is a profiling tool, distributed with the PGI Workstation suite. It can be used to analyse the performance of programs and supports OpenMPI and MPI programs. Информация взята v3.kz |
