Tracing OpenSHMEM* Applications

Intel® Trace Collector supports tracing of OpenSHMEM* applications on Linux* OS. If an application includes OpenSHMEM functions, the tool traces them and stores as a separate group in the trace file. This support is enabled in the libVT library, while the other tracing libraries listed in Product Components do not have this functionality.

Note

You need to have an MPICH-based MPI library available in LD_LIBRARY_PATH.

For OpenSHMEM implementations utilizing MPICH-based MPIs, to trace an OpenSHMEM application, follow the steps described in Tracing Conventional MPI Applications. No additional steps required.

For other OpenSHMEM implementations, trace the application as follows:

$ LD_PRELOAD=libVT.so:libmpi.so oshrun -n 4 ./shmem-app

SHMEM launchers are not provided within the Intel Trace Analyzer and Collector package.
