Hello,
thanks for the quick answer. I am sorry that I forgot to mention this: I
did compile OpenMPI with MPI_THREAD_MULTIPLE support and test if
required == provided after the MPI_Thread_init call.
I do not see any mechanism for protecting the accesses to the requests to a
single thread? Wh
David,
I do not see any mechanism for protecting the accesses to the requests to a
single thread? What is the thread model you're using?

using MPI_Isend and MPI_Irecv for communication and MPI_Test/MPI_Wait to
check if it is done. I do this repeatedly in the outer loop of my code.
The MPI_Test is used in the inner loop to check if some function can be
