Re: [OMPI users] [EXTERNAL] Re: Using shmem_int_fadd() in OpenMPI's SHMEM

Hi Howard/OpenMPI Users, I have had a similar seg-fault this week using OpenMPI 2.1.1 with GCC 4.9.3 so I tried to compile the example code in the email below. I see similar behavior to a small benchmark we have in house (but using inc not finc). When I run on a single node (both PE’s on the sa

Steve, We have been able to get OpenMPI 2.1 and 3.0 series working on our POWER9 systems. It is my understanding that the IBM offering has performance improvements over the open source variant. I would add the caveat we are still in fairly early testing of the platform. S. — Si Hammond Scalab

[OMPI users] Compiling OpenMPI 1.8.1 for Cray XC30

Hi OpenMPI developers/users, Does anyone have a working configure line for OpenMPI 1.8.1 on a Cray XC30? When we compile the code ALPS is located but when we run compiled binaries using aprun we get n * 1 ranks rather than 1 job of n ranks. Thank you. S. -- Simon Hammond Scalable Computer Arc

[OMPI users] Segmentation Fault when using OpenMPI 1.10.6 and PGI 17.1.0 on POWER8

Hi OpenMPI Users, Has anyone successfully tested OpenMPI 1.10.6 with PGI 17.1.0 on POWER8 with the LSF scheduler (—with-lsf=..)? I am getting this error when the code hits MPI_Finalize. It causes the job to abort (i.e. exit the LSF session) when I am running interactively. Are there any materi

We have occasionally had a problem like this when we set LD_LIBRARY_PATH only. On OSX you may need to set DYLD_LIBRARY_PATH instead ( set it to the same lib directory ) Can you try that and see if it resolves the problem? Si Hammond Sandia National Laboratories Remote Connection -Origin

Hi OpenMPI Team, We have recently updated an install of OpenMPI on POWER9 system (configuration details below). We migrated from OpenMPI 2.1 to OpenMPI 3.1. We seem to have a symptom where code than ran before is now locking up and making no progress, getting stuck in wait-all operations. While
