[Mvapich-discuss] Async progress

[Victor Eijkhout]

We have mvapich-gdr on an IBM power9 cluster, and these setting:

export MV2_ASYNC_PROGRESS=1
export MV2_OPTIMIZED_ASYNC_PROGRESS=1

Give the following errors, on basically any program:

Error in system call pthread_mutex_unlock: Operation not permitted
src/mpid/ch3/channels/mrail/src/rdma/ch3_progress.c:428
Error in system call pthread_mutex_lock: Resource deadlock avoided
src/mpid/ch3/src/ch3u_eager.c:767
Error in system call pthread_mutex_unlock: Operation not permitted
src/mpid/ch3/channels/mrail/src/rdma/ch3_progress.c:428

Any ideas?

Victor.
