Same window or different windows? Jeff On Wed, Mar 29, 2017 at 5:59 PM Sebastian Rinke <[email protected]> wrote:
Dear all,
I have some issue with MPI_Win_lock in MPICH-3.1.4 on Blue Gene/Q.
Here is my example:
Process 0:
Win_lock(MPI_LOCK_SHARED, target=A) Win_lock(MPI_LOCK_SHARED, target=B)
No matter what I use for A and B (given A != B), a process cannot acquire more than one lock at a time.
To my understanding, it should be possible to acquire more than one lock.
Can you confirm this issue?
Thanks, Sebastian _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
