I believe the iWARP build will work over IB too. The difference, I
think, is that the iWARP build uses the RDMA-CM and the IB build uses
the IB-CM.
Shaun, is this correct?
If so, I suggest you define these options differently. Perhaps IBCM vs
RDMACM? Right now it implies that you cannot run the same mvapich build
over both transports.
My 2 cents.
Steve.
