Re: [OMPI users] [EXTERNAL] OpenMPI 3.0.1 and Power9

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] OpenMPI 3.0.1 and Power9

Re: [OMPI users] mpi send/recv pair hangin

Using icc will not change anything unless there is a bug in the gcc version. I personally never build Open MPI with icc as it is slow and provides no benefit over gcc these days. I do, however, use ifort for the Fortran bindings. -Nathan > On Apr 10, 2018, at 5:56 AM, Reuti wrote: > > >>> Am
