Tracing OpenSHMEM Applications

Intel® Trace Collector supports tracing of OpenSHMEM* applications on Linux* OS. If an application includes OpenSHMEM functions, Intel Trace Collector 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
Note that we do not provide SHMEM launchers within the ITAC package.
 

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
