Re: [OMPI users] Relocating an Open MPI installation using OPAL_PREFIX

I honestly haven't thought through the ramifications of doing a multi- lib build with OPAL_PREFIX et al. :-\ If you setenv OPAL_LIBDIR, it'll use whatever you set it to, so it doesn't matter what you configured --libdir with. Additionally mca/ installdirs/config/install_dirs.h has this by de

[OMPI users] using the carto facility

I was advised for a benchmark to use the OPAL carto option to assign specific cores to a job. I searched the web for an example but have only found one set of man pages, which is rather cryptic and needs the knowledge of the programmer rather than an end user. Has anybody out there used this opt

It is currently a known limitation - shared memory currently only works between procs from the same job. There is an enhancement coming that will remove this restriction, but it won't be out for some time. Ralph On Jan 5, 2009, at 1:06 AM, Thomas Ropars wrote: Hi, I've tried to use ompi-s

[OMPI users] using ompi-server on a single node
