I offered to do tests on 4x8 core Opteron system (32 cores total), but = was discouraged that contention would be too much and results = meaningless -- yet, such systems will be more and more popular. > Does ULE care (much) if the nodes are hyperthreading or real cores? > Would that play a part in what it tries to schedule/spread? 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 :) Daniel=
