yes, understood, i compiled
Michael,
in this case, you can
mpirun --mca oob ^ud ...
in order to blacklist the oob/ud component.
an alternative is to add
oob = ^ud
in /.../etc/openmpi-mca-params.conf
If Open MPI is installed on a local filesystem, then this setting can
be node specific.
That being said, the error suggest
i'm trying to compile openmpi to support all of our interconnects,
psm/openib/mxm/etc
this works fine, openmpi finds all the libs, compiles and runs on each
of the respective machines
however, we don't install the libraries for everything everywhere
so when i run things like ompi_info and mpirun
