I am testing out the beta for Intel MPI 4.0. I am having a problem where my application (WRF V3.0.1) is hanging in MPI_Finalize when a large number of cores are being used (>1024). The OS is Centos 5.3 and I am using OFED-1.4.1.
Is the the right place to ask questions about the beta? If not, where is?
If it is, what options do I have for debugging so that I can gather up the right information for Intel developers?
