You're probably going into uncharted territory at least to some extent, but various people have been gathering experiences with 64-bit platforms. I'm not rich enough to have hands-on experience, but my impression is that things are quite dependent on the precise platform. The free software OS's are generally quite well standardized so that you can use (near-)standard procedures to get going. The commercial ones will require some elbow grease to get compiler switches and library settings right, and to get various support libraries (readline, jpeg, bz, etc.) in place. Then again, there are preciously few platforms that support that kind of memory size - I know that Sun will, but the speeds that I have seen from their CPUs have not been impressive. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
