yes this works just fine > 2) Since either A&B both have access to the 8MB cache, then > if a process was running on "A", it seems it would have a > low migration cost to be scheduled on "B" -- i.e. shouldn't > the process, if it were migrated to "A"'s "cache-mate", "B", > be able to benefit by any previous caching done on "A"? > If that's true, does the scheduler give preference, when > migrating a process, to a CPU's "cache-mate"? afaik yes as well - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
