Re: [OMPI users] restricting a job to a set of hosts

Application processes will *only* be placed on nodes included in the allocation. The -nolocal flag is intended to ensure that no application processes are started on the same node as mpirun in the case where that node is included in the allocation. This happens, for example, with Torque, where

Re: [OMPI users] restricting a job to a set of hosts

I was under the impression that the -nolocal option keeps processes off the submit host (since there may be hundreds or thousands of jobs submitted at any time, and we don't want this host to be overloaded). My understanding of what you said in you last email is that, by listing the hosts, I

Ah - okay, my misunderstanding. Would you be willing to give the trunk a try? It might help to know if the problem is solely in 1.6, or continues. On Jul 26, 2012, at 4:32 PM, Brock Palen wrote: > I think so, sorry if I gave you the impression that Rmpi changed, > > Brock Palen >

Guess I'm confused - your original note indicated that something had changed in Rmpi that broke things. Are you now saying it was something in OMPI? On Jul 26, 2012, at 4:22 PM, Brock Palen wrote: > Ok will see, Rmpi we had working with 1.4 and has not been updated after > 2010, this this

Ok will see, Rmpi we had working with 1.4 and has not been updated after 2010, this this kinda stinks. I will keep digging into it thanks for the help. Brock Palen www.umich.edu/~brockp CAEN Advanced Computing bro...@umich.edu (734)936-1985 On Jul 26, 2012, at 7:16 PM, Ralph Castain wrote:

Ralph, Rmpi wraps everything up, so I tried setting them with export OMPI_plm_base_verbose=5 export OMPI_dpm_base_verbose=5 and I get no extra messages even on helloworld example simple MPI-1.0 code. Brock Palen www.umich.edu/~brockp CAEN Advanced Computing bro...@umich.edu (734)936-1985

Re: [OMPI users] OpenMPI and Rmpi/snow

Well, it looks like comm_spawn is working on 1.6. Afraid I don't know enough about Rmpi/snow to advise on what changed, but you could add some debug params to get an idea of where the problem is occurring: -mca plm_base_verbose 5 -mca dpm_base_verbose 5 should tell you from an OMPI

Re: [OMPI users] OpenMPI and Rmpi/snow

Weird - looks like it has done a comm_spawn and having trouble connecting between the jobs. I can check the basic code and make sure it is working - I seem to recall someone else recently talking about Rmpi changes causing problems (different ones than this, IIRC), so you might want to search

I'm trying to replace the usage of platform mpi with open mpi. I am trying to compile on Windows 7 64 bit using Visual Studio 2010. I have added the paths to the openmpi include and library directories and added the libmpid.lib and libmpi_cxxd.lib to the linker input. The application compiles

[OMPI users] OpenMPI and Rmpi/snow

I have ran into a problem using Rmpi with OpenMPI (trying to get snow running). I built OpenMPI following another post where I built static: ./configure --prefix=$INSTALL/gcc-4.4.6-static --mandir=$INSTALL/gcc-4.4.6-static/man --with-tm=/usr/local/torque/ --with-openib --with-psm

[OMPI users] restricting a job to a set of hosts

I have a purely parallel job that runs ~100 processes. Each process has ~identical overhead so the speed of the program is dominated by the slowest processor. For this reason, I would like to restrict the job to a specific set of identical (fast) processors on our cluster. I read the FAQ on
