[OMPI users] resolving warnings about OpenFabrics not being found

I am getting warnings that OpenFabrics is disabled on one of our queues, but not the other. Does anyone know how to check if the OpenFabrics packages are installed? I'd like to verify if they are installed, and if not ping our IT group. best, David

Re: [OMPI users] how to build with memchecker using valgrind, preferable linux distro install of valgrind?

Thanks! I built against a locally built valgrind and ran valgrind on a mpi program, there's a lot of noise, but hopefully it will be useful to mpi developers here. Related to building a mpi debug package, is there a simple example of using vampirtrace? I've * found documentation on running

Re: [OMPI users] how to build with memchecker using valgrind, preferable linux distro install of valgrind?

The key is that you need to specify --with-valgrind=valgrind_install_dir -- not the path to the valgrind executable. Additionally, there's a valgrind.h that you'll need to have in that tree. E.g., if you specify --with-valgrind=/opt/valgrind, then it expects to find

Maybe just --with-valgrind or --with-valgrind=/usr would work? On 07/14/2016 11:32 AM, David A. Schneider wrote: I thought it would be a good idea to build a debugging version of openmpi 1.10.3. Following the instructions in the FAQ:

Re: [OMPI users] openmpi 1.10.2 and PGI 15.9

You can also simply copy slurm (omitting the .la) into an other directory, remove the .la, and pass this directory to Open MPI an other option is to compile slurm with PGI compilers, so your *.la should work fine. You might be luckier by rebuilding slurm with gnu compilers and

Re: [OMPI users] openmpi 1.10.2 and PGI 15.9

No, you have to manually edit those two .la files by hand after installation. It's basically a libtool problem. It generates the .la file with an option that PGI dsoesn't understand. On 07/14/2016 04:06 PM, Michael Di Domenico wrote: > On Mon, Jul 11, 2016 at 9:52 AM, Åke Sandgren

Where in the code does the tree based launch via ssh occur in open-mpi? I have read a few articles, but would like to understand it more, specifically the code that does it. Thanks Sent from my Verizon, Samsung Galaxy smartphone
