Support for other MPI implementations

Question

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

Answer

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

  • Intel® MPI Library 3.x for Linux*
  • Intel MPI Library 2.x for Linux*
  • MPICH*
  • SGI* MPT

The desired version of the Intel® Trace Collector Library can be picked during installation.

To verify which version you're using, check the value of the VT_MPI environment variable after sourcing the <install_dir>/itac/7.2/bin/itacvars.[c]sh script.

Alternatively, make sure that the symbolic links <install_dir>/itac/7.2/lib and <install_dir>/itac/7.2/slib point to the correct place.

For example, to use the Intel® MPI Library installation, make sure that:

lib -> ./itac/lib_impi3
slib -> ./itac/slib_impi3

 

To use the MPICH installation, make sure that:

lib -> ./itac/lib_mpich
slib -> ./itac/slib_mpich
