Other debug. I saw this and tried with: rmaps_base_oversubscribe = 1 rmaps_base_inherit = 1 written in $prefix/etc/openmpi-mca-params.conf of all nodes with no luck. I think my problem is somehow related to this https://github.com/open-mpi/ompi/pull/

Re: [OMPI users] When is it save to free the buffer after MPI_Isend?

Hi all, Sorry no reply. I just figured out the solution. The problem was that I had a function that would MPI_Isend a message on every call to it. Then I'd store its request pointer to a list. My MPI_Isend snippet: MPI_Request req; MPI_Isend(blabla, &req) task_push(&req); >From time to time at
