Re: [OMPI users] new hwloc error

Try adding —hetero-nodes to the cmd line and see if that helps resolve the problem. Of course, if all the machines are identical, then it won’t > On Apr 29, 2015, at 1:43 PM, Brice Goglin wrote: > > Le 29/04/2015 22:25, Noam Bernstein a écrit : >>> On Apr 29, 2015, at

Re: [OMPI users] getting OpenMPI 1.8.4 w/ CUDA to look for absolute path to libcuda.so.1

Hi Lev: Any chance you can try Open MPI 1.8.5rc3 and see if you see the same behavior? That code has changed a bit from the 1.8.4 series and I am curious if you will still see the same issue. http://www.open-mpi.org/software/ompi/v1.8/downloads/openmpi-1.8.5rc3.tar.gz Thanks, Rolf

[OMPI users] getting OpenMPI 1.8.4 w/ CUDA to look for absolute path to libcuda.so.1

I'm trying to build/package OpenMPI 1.8.4 with CUDA support enabled on Linux x86_64 so that the compiled software can be downloaded/installed as one of the dependencies of a project I'm working on with no further user configuration. I noticed that MPI programs built with the above will try to
