All, in adding two new blade centers full of machines to my existing cluster install, I'm getting the following errors in trying to run MPI jobs over MVAPICH ::

libibverbs: Fatal: no infiniband class devices found.
No IB device found


Please send the output of lspci -v for the IB card.

Also - to see which kernel modules are loaded please run: lsmod | grep ib

If you have OFED installed on the system you can find the prefix running the script: /etc/infiniband/info

The binaries are installed under <prefix>/bin
