I just wanted to know how well a computer using >32 processors and 256 GB of ram will perform against a GM or a Dual. If it is a NUMA machine, the dual will probably kill it until the program is modified to work on that kind of architecture. In a classic NUMA machine, it is possible for 32 processors to run slower than one processor, if memory usage is not very carefully controlled.
