Command to collect basic trace info of an OpenMP application supporting OMPT
interface:
$ AMDuProfCLI collect --trace openmp --openmp-impl ompt --openmp-scope basic -o /tmp/myapp_perf <openmp-app>Command to profile an OpenMP application compiled with GCC OpenMP
library:
$ AMDuProfCLI collect --trace openmp --openmp-impl omplib -o /tmp/myapp_perf <openmp-app>Use the --openmp-impl option to provide OpenMP implementation type:
ompt for tracing of OpenMP libraries supporting OMPT interface
(example: LLVM, AOCC, ICC), omplib for tracing GCC OpenMP library.
If --openmp-impl is not specified, the default selection is
ompt.
Use
--openmp-scope option to provide tracing
scope: full for tracing all the OpenMP events,
basic for basic tracing, where synchronization
related OpenMP events are not traced to reduce the disk space usage. If --openmp-scope is not specified, the default selection
is basic.Note: This option is only applicable with
--openmp-impl ompt.While performing the regular profiling, add option --trace openmp --openmp-impl <ompt | omplib> to enable OpenMP profiling. This command will launch the program and collect the profile data required to generate the OpenMP analysis report.
Once profile data collection is complete, a session directory will be generated. Use session directory to generate the csv report (or) to import the session in GUI.
Refer CLI collection for all supported options.
