What used to be Pallas, now Intel's IMB (v3.2) is what you are looking for:
http://software.intel.com/en-us/articles/intel-mpi-benchmarks/

Compile against your MPI environment and run. Very detailed instructions 
are provided. I would suggest the Alltoall test method within IMB, it is 
a good way to stress your topology.
