You can learn more about multithreading support in MPI from the standard (www.mpi-forum.org/docs/mpi-3.1/mpi31-report.pdf) in section 12.4. If you need us to help, we need more information such as configure line, target platform, compiler version, and most importantly, a toy program that reproduces the bug. --Halim On 7/31/15 4:41 AM, Viswanath Krishnamurthy wrote:
I did try initializing Multithreading support #include<mpi.h> int main() {

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.
Thanks, Viswanath

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
