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?
