Mark, Thanks a lot for clearing this up, you really put me on track.One more thing however, before I have a go at the cm configuration: regarding xstat_cm_test, what are {d,v}{local,remote}Accesses ? Do they correlate with cache hits somehow so one can infer the cache misses? For reference, here's what xstat_cm_test tells me:
