Yes, I had that in mind ofc., but at home i only have AMD boxes (+1 i7 box) just because I'm a contrarian ;). That's why I rechecked on an Intel box@office. For testing/implementing concurrent applications opterons are not that bad, being contention detectors. On a side node, the best overall absolute throughput could be observed on the opteron machine (though much cheaper). Would be interesting to also run the test on my FX8350@4Ghz instead of the 2Ghz opteron, but no time for now .. Unfortunately the test uses floating point a lot, so I cannot check how the Int-only cores of the AMD machines behave compared to Hyperthreading in reality.
