Forget about using the P4 in a 1U configuration. The voltage regulator on
the motherboard takes up more than 1U. You will need to work with a 2U
footprint as a minimum. You can get the AMD MP in a 1U, but, beware of the
heat issues, you will need above average air flow.

Subject: CPU Choices
(sorry if this gets posted twice)
I am doing some research into the configuration of a 32 1U node Beowulf
and have a question regarding CPU configuration.
The current choice is between Intel P4s as Itaniums seem a little bleeding
the moment, or the latest AMD chips.
AMD seem to be getting a impressive performance for the price, but I?m a
concerned about the lack of mature multiprocessor chipsets and their heat
Intel on the other-hand have the MP chipsets but seem to be falling down
current lack of (non-commercial ) complier that support MMX and SSE, and the
whole issue of Rambus Vs DDR memory.
I would be grateful for any insight into a choice of CPU and its
terms of price/performance/expandability, or any other factor I should be
