We have an SP2, with 4 processors (which in theory is the best price/performance you can get) and the guys that handle it report it isn't fast and that they need more resources for it. I must admit that even with all the courses they have received from IBM they have showed to be very incompetent in different areas, but with all those IBM engineers coming in and out (my campus is very important in a national level) for about two years now, I would expect more results. Maybe parallel computing is cost effective but I haven't noticed it :(. > D.Wood and M.Hill, "Cost-Effective Parallel Computing", > IEEE Computer, Feb 1995 > Thanks for the reference...I'll look for it.
