[hwloc-users] Magny Cours L3 cache issue

2011-08-15 Thread Wheeler, Kyle Bruce
Hello, I'm having the problem that my Magny Cours system is being identified (via hwloc-ls) as sharing an L3 cache between the NUMAnodes on a single socket. I know that this is not actually true, and I don't know how to begin debugging hwloc to see why it thinks that about the L3 cache. Thought
