Jeff Becker (CC'ed) reported to me a failure with hwloc 1.7.2 (in OMPI trunk). I had him verify this with a standalone hwloc 1.7.2, and then had him try standalone hwloc 1.8 as well -- all got the same failure.
Here's what he's seeing in 1.7.2: $ lstopo Different OS indexes lstopo: topology-linux.c:2731: look_sysfsnode: Assertion `node == res_obj' failed. Aborted (core dumped) In 1.8, the issue is the same, but a different line number (2741). It's an SGI x86_64 server, running SLES 11. Is this an hwloc issue, or a hardware issue? -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
