[OMPI users] How to check that open MPI installed and work correctly

Hi, I installed open MPI on Linux cluster which consist of three machines. I want to ask how can I check that open MPI work correctly and is there a special configurations that I need to set to make the machines connect to each other because I just installed open MPI without making extra confi

Re: [OMPI users] SIGTERM propagation across MPI processes

That is great news! I also would have voted to remove the bindings. Boost.MPI is the only library i ever used for MPI in C++, it's a much better designed object-oriented library, not just bindings. ;-) With Boost.MPI we can send our own types through MPI messages by serializing the objects, which

Re: [OMPI users] SIGTERM propagation across MPI processes

I doubt anything will be done about those warnings, given that the MPI Forum has voted to remove the C++ bindings altogether. On Mar 25, 2012, at 12:36 PM, Júlio Hoffimann wrote: > I have no much time now for trying a more recent version, but i'll keep that > in mind. I also dislike the warnin

Re: [OMPI users] SIGTERM propagation across MPI processes

I have no much time now for trying a more recent version, but i'll keep that in mind. I also dislike the warnings my current version is giving me ( http://www.open-mpi.org/community/lists/devel/2011/08/9606.php). I'll see how to contact Ubuntu maintainers to update OpenMPI and solve both problems i

[OMPI users] Data distribution on different machines

Hi, I want to distribute the data on different machines using open mpi. I am a new user. Can some one point me to the resources or atleast functions i would have to use to complete the task? I am using red hat linux. Thanks, --

Re: [OMPI users] SIGTERM propagation across MPI processes

I forgot to mention, i tried to set the odls_base_sigkill_timeout as you told, even 5s was not sufficient for the root execute it's task, and most important, the kill was instantaneous, there is no 5s hang. My erroneous conclusion: SIGKILL was being sent instead of SIGTERM. About the man page, at
