Question

Does the Intel® Trace Analyzer and Collector support different MPI implementations?

Answer

Yes. The Intel® Trace Analyzer and Collector supports the following MPI implementations:

  • Intel® MPI Library 3.x for Linux*
  • MPICH* and all of its variants (e.g. MPICH3)
  • Any other MPICH-based MPI implementations

Support for all of these is available by simply linking with the default libVT.so or libVT.a library.

If your preferred MPI implementation is not listed here, you can easily check if the Intel Trace Collector interface is binary compatible with that of your local MPI library.  That's done by compiling and running the examples/mpiconstants.c program with your MPI.  Then check the values you get with the values listed in section 1.2 System Requirements and Supported Features of the Intel Trace Collector Reference Manual.  If they match, you're good to go.

Product and Performance Information

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.
