Hi! I have used Windows Server, just now will change my OS with Debian. My system is AMD(opteron) two cpus and data bus, 32 bits and 64 bits. I used this system for calculating heavy load, such as differential equations. I want to know whether Debian is proper to my system? Moreover, which debian (woody or potato) is proper? However, I can not find any information about adaptation on debian on your homepage. How about your view? Thanks. bye~
