Rambabu,
I talked it over with Kevin and I am going to upgrade the Levitee computer to a 64bit Vista Windows and put another 4Gb of memory in it in order to run the larger simulations. I will be coming around today after 3pm to take the computer and should have it back by tomorrow. I plan to dual boot XP pro on one partition for Arash to run his sims and Vista 64Bit on another 320GB partition for our stuff. The good news is that I have a customer who has a use for the extra motherboard.
