I need to run a windows based simulation software for my research work. It takes about 4 hr to complete the simulation on my AMD Athlon 2800+ with 1GB DDR400 RAM running on win xp sp2 platform. I want to complete the above simulation in 1 hr. Pls recommend server(s) for the same. You may notice that the main requirement is processing speed, not the reliability or the fail safe architecture of the server. If the multiple desktop can be connected to do the same, then give me the info. of the service providers who can do this.
