Hello, we are using a scientific application (ETABS) for structure analysis at work. Most of scientific applications code base dates back to single core CPUs era, when higher CPU clock meant faster execution. Here is the problem, we have Core2 Quad boxes (Q9550) with each core clocked at 2.83GHz, but mentioned program only uses one of the CPU cores at full blast, so it is limited by CPU clock rate. Is it possible to force applications to distribute the work load over all CPU cores, or if not possible make it somehow run faster without over clocking the CPUs? Is upgrading them to Core2/CoreiX extreme editions with higher clocks only option?
