The ATLAS application indeed bears the fancy name
1.01 (vbox64_mt_mcore_atlas)
where mt_mcore seems to imply multithread and multicore. The Virtual boxes I have can be manipulated to run on 1 to 8 cores, nothing about threads. Wonder how much threads it would take on the yet-to-be-released 32-core/64-thread Opteron - and how much on a system with two of those CPUs. Should finish quite a bit sooner than those running on our quads...
