[OMPI users] Hang in MPI_Send

2015-04-04 Thread Subhra Mazumdar
Hi, When I run my mpi job with openmpi 1.8.4, it hangs in the following stack: #0 0x7fe59e07b264 in __lll_lock_wait () from /lib64/libpthread.so.0 #1 0x7fe59e076508 in _L_lock_854 () from /lib64/libpthread.so.0 #2 0x7fe59e0763d7 in pthread_mutex_lock () from /lib64/libpthread.so.0
