I'm building a Beowulf cluster ( guess you never heard that before
:-) and I'd really appreciate some advice on some questions.
1. Is it better to get the fastest CPU or maybe something slower with more
2. From tutorials, papers and web pages I get the impression that it's better
to start with less nodes with better hardware, e.g.
4 PIV 1.4GHz 512 Mb RAM versus 8 PIII 700MHz 256 Mb RAM
( This example is merely illustrative - not wanting to dwell on the issue
PIII vs. PIV :-)
3. What is the performance penalty on running diskless nodes ? I mean,
comparing with a full/partial OS install on each node.
4. Could you recommend a good ethernet card/switch ? I've read the page on
Gigabit and 100Mbps ethernet technology and I'm inclined to adopt the
DEC "Tulip" model.
Thanks in advance
