Correct. To configure/compile the gm driver, you need
./configure ... -with-gm=/path/to/gm
Then that RPI becomes available for selection at run time. You can make
gm be the default with "--with-rpi=gm" on the configure line, but that is
overridable at run-time. See lamssi_rpi(7) for more details about
selecting which RPI to use at run time, and the tweakable run-time
parameters that are available.
For the moment, there's also doc/myrinet.txt. That will soon disappear
and reappear in doc/user/ somewhere, which will be a PDF user's guide in
the final tarball.
STRONG CAUTION: I would *NOT* trust the gm RPI for production-quality
results yet. We have run a lot of tests on it here, and it *looks*
stable, but it has not been heavily stress-tested yet.
HOWEVER: I would ***greatly*** appreciate people running their own MPI
codes "in the wild" on the gm RPI to see how well it does / does not do.
