configuration problem at our end and I was hoping that you might have some insight into what it might be based on the errors I’m seeing. I can try running with a few earlier versions of mpich and see if any of them work better.</span><o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:11.0pt">I’m testing the MPI-RMA runtime in Global Arrays and I’m getting a lot more crashes than I’ve seen in the past. The MPI-RMA runtime code is fairly stable and hasn’t been modified much
recently and all the tests used to pass using one of the more recent MPICH releases. However, I’m getting significant crashes at this point. One of them occurs in a program designed to test non-blocking communication. It creates an MPI window, using MPI_Alloc_mem
followed by MPI_Win_create and then calls MPI_Win_lock_all on the window. The code currently crashes when it gets to an MPI_Rput call. I’m trying to see if there is something different in the environment that might be causing this.</span><o:p></o:p></p>
