[ofa-general] List of all files and locations

[Robert Cummins]

Have you tried using lsmod to see what kernel modules are loaded?
What's the output from dmesg?  Are you even sure ib is up?  What does
ibnetdiscover return?  Do you have a lid?  Is your subnet manager
running?

Until you have verified that ib is working you're not likely to get an
MPI application to work.  I would start with something simple like
making sure you can ping (requires ipoib to be working) a remote node
over infiniband after you've verified the above before attempting to
launch the MPI application.

There are *many* reasons why you might be getting permission denied.
