Yes. I had to rebuild because I'd omitted openib when we only needed psm. As I said, I did exactly the same thing successfully with PMB (initially because I wanted to try an old binary, and PMB was lying around). >> Your MPI job is now going to abort; sorry. > ... >> [lvgig116:07931] 19 more processes have sent help message >> help-mca-bml-r2.txt / unreachable proc [lvgig116:07931] Set MCA parameter > > Seems to me that OpenMPI gave up because it didn't succeed in initializing > any > inter-node btl/mtl. Sure, but why won't it load the btl under IMB when it will under PMB (and other codes like XHPL), and how do I get any diagnostics? My boss has just stumbled upon a reference while looking for something else It looks as if it's an OFED bug entry, but I can't find an operational version of an OFED tracker or any other reference to the bug than (the equivalent of) http://lists.openfabrics.org/pipermail/ewg/2010-March/014983.html : 1976 maj jsquyres at cisco.com errors running IMB over openmpi-1.4.1 I guess Jeff will enlighten me if/when he spots this. (Thanks in advance, obviously.)
