mething the volatile keyword doesn't do on its own. I think it's also much cleaner as it eliminates an arbitrary sleep from the code - which I see as a good thing as well. "Ralph Castain via devel" ---11/12/2019 09:24:23 AM---> On

Re: [OMPI devel] Open MPI v4.0.1: Process is hanging inside MPI_Init() when debugged with TotalView

John, OMPI_LAZY_WAIT_FOR_COMPLETION(active) is a simple loop that periodically checks the (volatile) "active" condition, that is expected to be updated by an other thread. So if you set your breakpoint too early, and **all** threads are stopped when this breakpoint is hit, you might experienc

Re: [OMPI devel] Open MPI v4.0.1: Process is hanging inside MPI_Init() when debugged with TotalView

Hi John Sorry to say, but there is no way to really answer your question as the OMPI community doesn't actively test MPIR support. I haven't seen any reports of hangs during MPI_Init from any release series, including 4.x. My guess is that it may have something to do with the debugger interacti

[OMPI devel] Open MPI v4.0.1: Process is hanging inside MPI_Init() when debugged with TotalView

Hi, An LLNL TotalView user on a Mac reported that their MPI job was hanging inside MPI_Init() when started under the control of TotalView. They were using Open MPI 4.0.1, and TotalView was using the MPIR Interface (sorry, we don't support the PMIx debugging hooks yet). I was able to reproduce
