Hi George, I think you forgot the ierror argument in the call to mpi_irecv, but after correcting this it works fine. Thanks a lot for pointing out the issue of the eager limit!
But as you said, this does not directly solve my one-sided problem... Thanks, Stephan ________________________________ From: users [users-boun...@open-mpi.org] on behalf of George Bosilca [bosi...@icl.utk.edu] Sent: Tuesday, April 14, 2015 17:49 To: Open MPI Users Subject: Re: [OMPI users] mpi_type_create_struct not working for large counts This is one of the most classical bugs with point-to-point applications. Sends behave as non blocking as long as the amount of data is below the eager limit. Once the eager limit is passed, sends have a blocking behavior which requires that the peer has a posted receive. This explains why it is working for 100 but not for 1000. The correct application is attached below. This doesn’t validate the one-sided run thou.
