I did try initializing Multithreading support #include<mpi.h> int main() { int provided; int returnvalue = MPI_Init_thread(&argc,&argv,MPI_THREAD_MULTIPLE,&provided); if(provided < MPI_THREAD_MULTIPLE) { printf("\n THREAD LIBRARY DOESN'T HAVE MULTITHREADING SUPPORT:"); exit(1); } } The code compiles but throws an error - Assertion failed in file /home/viswa/libraries/mpich-3.1.4/src/include/mpiimplthreadpost.h at line 163: depth > 0 && depth < 10 internal ABORT - process 1 internal ABORT - process 0 Could you please refer me to some documentation for mpi_init_thread/ MPICH-multithreading documentation as I am relatively new to it.

I am a developer at Panasas, and we would like to provide a patch that removes RAID0 support and adds RAIDN support to romio (MPICH 3.2):

src/mpi/romio/adio/ad_panfs/ad_panfs_open.c

I currently do not have an MCS or trac account.

Thank You
