It seems to work pretty well at the moment, but it is too slow for my liking. I am in the process of optimizing the code, but there is a point where that will not help speed things up. The program does lots of memory allocation/deallocation and that seems to be it's speed downfall. So, I need a new box and I wanted to solicit input on some choices. First of all, I really plan to have this box dedicated to computational problems only, so I don't really need soundboards, fancy monitors, modems, etc. All that is required is a NIC, >= 256M ram, and high cpu+cache+bus performance. Of course I want to minimize price. The program could probably be threaded at a gross level, so SMP might ultimately be an option (even if not threaded?), but I was thinking of starting with a 800Mhz PIII machine. Does this rambling make sense? Can FBSD utilize the PIII features? Is there a hi-performance computation in FBSD FAQ?
