Subject: Re: [OMPI users] [OMPI devel] Configuring openmpi-1.3.2 with "--without-rte-support". FLAG.
From: Ralph Castain (rhc_at_[hidden])

That configure option does work, but you appear to be on a system that
has SLURM installed - yes? Are you planning on running with SLURM?

Building --without-rte-support will remove a lot more than just the
allocator and mapper. You have to be on a system like a Cray that has
its own launch, mapping, and MPI wireup support. Unfortunately, SLURM
doesn't meet all those requirements.

If you are trying to improve startup time, then you are probably
chasing the wrong areas. The allocation and mapping functions are only
loaded by mpirun, not any application process or daemon, and those
functions typically take only milliseconds to execute.

What problem are you trying to solve? We have a lot of capability for
improved launch times built into 1.3.2, and even more in the OMPI
development trunk that will be in future releases. Depending upon the
precise problem you are trying to resolve, we can perhaps point you to
a better solution.
