    Subject[PATCH] reduce inter-node balancing frequency
    Date
    Nick, we've had this patch floating around for awhile now and I'm wondering 
    what you think. It's needed to boot systems with lots (e.g. 256) nodes, but
    could probably be done another way. Do you think we should create a
    scheduler domain for every 64 nodes or something? Any other NUMA folks have
    thoughts about these values?

    Thanks,
    Jesse
