Hey Kevin,
The Intel® Trace Analyzer and Collector will support any MPICH2-compatible MPI implementation. If you're not sure if your implementation is not compatible, we provide an mpiconstants.c file you can compile and use to check the ABI compatibility. More info is available in the System Requirements section of the Intel® Trace Collector Reference Guide.
I hope this helps. Let me know if you have other questions.
Regards,
~Gergana
