Re: [OMPI devel] 1.10.3rc status

Thanks for analyzing this, Gilles - I guess this is a question for Edgar or someone who cares about MPI-IO. Should we worry about this for 1.10? I’m inclined to not delay 1.10.3 over this one, but am open to contrary opinions > On May 26, 2016, at 7:22 PM, Gilles Gouaillardet wrote: > > In my

Only thing I can think of is the request stuff. It was working last time I tested George’s branch. I will take a look at MTT tomorrow. -Nathan > On May 26, 2016, at 8:24 PM, Ralph Castain wrote: > > I’m seeing a lot of onesided hangs on master when trying to run an MTT scan > on it tonight -

[OMPI devel] One-sided failures on master

I’m seeing a lot of onesided hangs on master when trying to run an MTT scan on it tonight - did something go in that might be having trouble? Ralph

Re: [OMPI devel] 1.10.3rc status

In my environment, the root cause of MPI_File_open failing seems to be NFS. MPI_File_open(MPI_COMM_WORLD, "temp", MPI_MODE_RDWR | MPI_MODE_CREATE, MPI_INFO_NULL, &lFile); if the file does not previously exists, rank 0 creates the file, MPI_Bcast(), and then every rank open th

Ralph, the cxx_win_attr issue is dealt at https://github.com/open-mpi/ompi/pull/1473 iirc, only big endian and/or sizeof(Fortran integer) > sizeof(int) is impacted. the second error seems a bit weirdest at a time. once in a while, MPI_File_open fails, and when it fails, it always fails

Hello all With a git pull of roughly 4 PM EDT (US), that had a .m4 file (something to do with MXM) in the change set, mpirun does not work anymore. The failure is like this: [durga@b-2 ~]$ sudo /usr/local/bin/mpirun --allow-run-as-root -np 2 -hostfile ~/hostfile -mca btl lf,self -mca btl_base_ver

I’m seeing three errors in MTT today - of these, I only consider the first two to be of significant concern: onesided/cxx_win_attr : https://mtt.open-mpi.org/index.php?do_redir=2326 [**ERROR**]: MPI_COMM_WORLD rank 0, file cxx_win_attr.cc:50: Wi

Re: [OMPI devel] Open MPI v2.0.0rc2

Hi, > - Improved support for MPI_THREAD_MULTIPLE (when configured with --enable-mpi-thread-multiple). Just curious to know why this is not enabled by default. Are there any known issues ? I was able to run HPCC benchmark with np=56, without any issues. Hence, wondering. Please let me know.
