Can you try the HEAD with the mpi_yield_when_idle set to 0 please.

Short version: I'm seeing a large performance drop between r18850 and the SVN HEAD.Longer version:FWIW, I ran the tests on 3 versions on a woodcrest-class x86_64 machine running RHEL4U4:* Trunk HEAD (r18997)* r18973 --> had to patch the cpu64* thingy in openib btl to get it to compile* r18850I ran both osu_latency and NetPIPE 3.7.1. In the r18997 and r18973, the latency for short sends over sm is *significantly* higher than that of r18850.
