I offered to do tests on 4x8 core Opteron system (32 cores total), but =

meaningless -- yet, such systems will be more and more popular.

I could also run the tests on 2x4x2 cores Xeon, which uses hyper =
threading, 8 real or 16 virtual cores in total.

I can torture both systems (actually two pairs) for a week or two. But I =
may not have enough time to prepare the core/setup so any advice is =
greatly appreciated. Be more descriptive :)
