[OMPI users] a question about MPI dynamic process manage

Hi team: I have a question about MPI dynamic process manage, I hope you can provide some help. First of all, the MPI program running on multiple nodes, the group with MPI_COMM_WORLD was splitted into some subgroups by nodes and sub-communicators were created respectively so that MPI proces

Hi Goetz Thanks for trying these other versions. Looks like a bug. Could you post the config.log output from your build of the 2.1.0 to the list? Also could you try running the job using this extra command line arg to see if the problem goes away? mpirun --mca btl ^vader (rest of your args) H

Hello; I am converting some fortran 90/95 programs from the 'mpif.h' include file to the 'mpi_f08' model and have encountered a problem. Here is a simple test program that demonstrates it: __- program testf08 !

[OMPI users] Help with Open MPI 2.1.0 and PGI 16.10: Configure and C++

All, I'm hoping one of you knows what I might be doing wrong here. I'm trying to use Open MPI 2.1.0 for PGI 16.10 (Community Edition) on macOS. Now, I built it a la: http://www.pgroup.com/userforum/viewtopic.php?p=21105#21105 and found that it built, but the resulting mpifort, etc were just not

Sorry folks - for some reason (probably timing for getting 2.1.0 out), the fix for this got pushed to v2.1.1 - see the PR here: https://github.com/open-mpi/ompi/pull/3163 > On Mar 22, 2017, at 7:49 AM, Reuti wrote: > >> >> Am 22.03.2017 um 15:31

Roland, the easiest way is to use an external hwloc that is configured with --disable-nvml an other option is to hack the embedded hwloc configure.m4 and pass --disable-nvml to the embedded hwloc configure. note this requires you run autogen.sh and you hence needs recent autotools. i guess Open

Dear Reuti, thanks a lot, you're right! But why did the default behavior change but not the value of this parameter: 2.1.0: MCA plm rsh: parameter "plm_rsh_agent" (current value: "ssh : rsh", data source: default, level: 2 user/detail, type: string, synonyms: pls_rsh_agent, orte_rsh_agent)

Hi everyone, I'm testing a new machine with 32 nodes of 32 cores each using the IMB benchmark. It is working fine with 512 processes, but it crashes with 1024 processes after a running for a minute: [pax11-17:16978] *** Process received signal *** [pax11-17:16978] Signal: Bus error (7) [pax11-17:

Dear users and developers, first of all many thanks for all the great work you have done for OpenMPI! Up to OpenMPI-1.10.6 the mechanism for starting orted was to use SGE/qrsh: mpirun -np 8 --map-by ppr:4:node ./myid /opt/sge-8.1.8/bin/lx-amd64/qrsh -inherit -nostdin -V orted --hnp-topo-sig
