Today I went to my local computer store, and they offered me a couple of possibilities: Asus A7V266-E Motherboard with 2GHz AMD Athlon XP or Tyan S2460 Dual MP Socket A with dual AMD 1.8 GHz Athlon MP. I am wondering which is the best way to go, and I really don't understand how the dual processors would work. Let me ask some questions about the dual option. (I am asking here, because I specifically want to know how FreeBSD will work with this system.) 1. If I run one program, will it only use one of the MP processors? 2. If I run two seperate programs, will they each use one of the MP processors, and each go with the speed of 1.8GHz, in effect running the programs as if they are on two seperate 1.8GHz computers. 3. The salesperson I was speaking two said that these processors were designed to talk to each other in some way - I think he used the phrase "sharing threads." What does this mean?
