could you please explain what do you mean with "high speed networks"?
Gigabit ethernet or its proprietary, low latency competitors?
I'm asking because we plan to buy a Myrinet cluster with Athlon MPs
(AMD MPX chipset) or Xeon DPs (ServerWorks GC LE). The question is:
Buy a few high clock/high price (e. g. Xeon DP 2.8 GHz) or many lower
clock/low price CPUs (e. g. Athlon MP 2600+)?
BTW, is anybody out there with Xeons on Intel E7501 chipset systems?
Are there any problems with Linux supporting the chipset?
Thanks in advance for your help
