[ofa-general] MPI IB Errors

[John Leidel]

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

All machines are essentially the same archticture... 2.8Ghz opterons.  All
are running TopSpin/Cisco IB gear.  The blade centers both has internal IB
switches, to which I have connected to our existing TopSpin core switch.  I
disabled the subnet managers on both blade chassis IB switches as I'm
running the subnet manager from the IB core switch.


Any thoughts on what is going on?
