Subject: [hwloc-users] hwloc problem on SGI machine
From: Jeff Squyres (jsquyres) (jsquyres_at_[hidden])

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?
