The best place to pose these Altix related questions would be the LSE-Tech mailing list at SourceForge. Everything discussed there relates to Linux on NUMA machines, and the ongoing patch work related to this effort.
Pose your questions to [EMAIL PROTECTED], and ask to be cc'd if you're not subscribed to the list. I would recommend subbing though, as one can learn quite a bit from the discussions.
