Subject: Re: [OMPI users] Tons of warnings in running my first openmpi job
From: Jeff Squyres (jsquyres_at_[hidden])

It looks like your version of Open MPI is compiled and linked against the DAPL library, but the DAPL library is not present on your system (or it is incorrectly installed...? I'm not very familiar with DAPL). You should probably contact your sysadmin to ask about the DAPL installation.

FWIW, DAPL is not recommended for Linux systems. It is mainly in the Open MPI code base to support Solaris.

You should be able to avoid these warnings by editing the Open MPI system-wide run-time parameters file and adding the following:

btl = ^udapl

This tells Open MPI to load all BTL plugins *except* the "udapl" plugin.

I don't know where the Open MPI system-wide param file will be installed on your system; look for a file named "openmpi-mca-params.conf".
