Hi,
Can MPI_THREAD_MULTIPLE and openib btl work together in open mpi 1.8.4? If
so are there any command line options needed during run time?
Thanks,
Subhra.

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
