Per Brian's recent MTL updates, the PSM MTL is busted. I notice the following when I run on a machine that has the PSM software stack installed:
[ompi_r00lez:19108] mca: base: component_find: unable to open /scratch/local/jsquyres/bogus/lib/openmpi/mca_mtl_psm: /scratch/local/jsquyres/bogus/lib/openmpi/mca_mtl_psm.so: undefined symbol: ompi_mtl_psm_imrecv (ignored)
I'll file a bug about this; I'm assuming this is an issue the 1.7 RMs will care about.
