Oops. One key typo here: This is the IMB-MPI1 gather test, not
barrier. :(

Hi,
I'm debugging a performance problem with running IMB-MP1/barrier in an
NP64 cluster (8 nodes, 8 cores each). I'm using openmpi-1.4.1 from the
OFED-1.5.1 distribution. The BTL is openib/iWARP via Chelsio's T3
RNIC. In short, a NP60 and smaller run completes in a timely manner as
expect
