Amesos Umfpack Parallel Hang
Created by: tgvoskuilen
I have been experiencing intermittent parallel hangs on multi-processor jobs using umfpack (solver block below). I've run it in the debugger and it's just sitting at two different MPI calls within the umfpack solver code. I captured matrix files for the case where it hangs and can provide them too.
begin trilinos equation solver directVerbose solution method = amesos-umfpack fei output level = matrix_files end
