Hi,
from what you describe below, seems as if you did not configure well
OpenMPI.
You issued
./configure --with-ft=cr --enable-mpi-threads --with-blcr=/usr/local/bin --with-blcr-libdir=/usr/local/lib
while according to the installation paths you gave it should have been
more like
./configure --with-ft=cr --enable-mpi-threads --with-blcr=/root/MS --with-blcr-libdir=/root/MS/lib
Apart from that, if you wish to have BLCR modules loaded at start up of
your machine, a simple way is to add the following lines in rc.local
This file is somewhere in /etc: the exact location can vary from one linux
distribution to another (e.g.: /etc/rc.d/rc.local or /etc/rc.local)
/sbin/insmod /usr/local/lib/blcr/2.6.23.1-42.fc8/blcr_imports.ko
/sbin/insmod /usr/local/lib/blcr/2.6.23.1-42.fc8/blcr.ko
Just in case, if you have multiple MPIs installed, you can check which
you are using with the following command:
which mpirun
