[Pypar-developers] Error when trying to import PyPar

[Craig F. <cf...@ie...>]

I get the following error message when I try "import pypar" at the Python command line, and when I attempt to submit a PyPar job through our job submission system:

[rdma_iba_init.c:91] Error initializing MVAPICH2 malloc library
Fatal error in MPI_Init: Other MPI error, error stack:
MPIR_Init_thread(230): Initialization failed
MPID_Init(81)........: channel initialization failed


It seems like PyPar is having trouble starting the MVAPICH2 library, but I don't know why.  I checked with our system admin, and he verified that I was submitting the jobs correctly.  We verified that my "mpirun" executable is the same version of MPI that I used to build the PyPar extension.  I don't know where to go from here, because the error message isn't very helpful.  Does anyone have any suggestions about what might be causing the problem, or how I might get a more detailed error message?  Thanks!

NOTE: PyPar builds and runs fine on my dual-core desktop PC (gcc and openmpi).  I am having trouble on a RedHat Enterprise cluster, which uses the Intel C and Fortran compilers and mvapich2-0.9.8-15.  We also have mvapich-0.9.9 and openmpi-1.2.2-1 which I might try next.
