[quote="Prime Monster"][quote="clowns789"]Xyzzy,

When you get the computer to George you should ask Prime Monster if he needs any more motherboards. I noticed he has a server connected to a hub and then ten P4 motherboards and one AMD. I think it might be interesting to contribute if he wants. I'll PM him too.[/quote]

I actually have 24 mobos (11 P4s, 7 AMD XPs and 6 PIIIs) running headless/diskless/etc :D and yes I am looking for some new boards, but not immediately. Will probably go for a P4 combo again, as I feel quite comfortable with them.

PM[/quote]
Are you waiting for the release of the Athlon64 and P5, so you can pick up some P4's on the cheap side :) ?

It appears that the Redhat preview does not support 32-bit mode, so tonight I'm going to put SuSE on... I'll email updated login info to everyone ASAP...

Here is a benchmark from SuSE... I'm pretty sure it is in 32-bit mode...

No... The 501 just happens to have a router built in... No other PIX (AFAIK) does... It is geared more towards the SOHO market...[/quote]

Thanks Xyzzy.

Could you make a benchmark with disabled SSE2 please? If there are really harming SSE2 issues then x87 code could be a little faster.

Thank you.

Only little differences between x87 and SSE2 here... very interesting. It looks like the current code is limited by one of the architectural units (FPU, cache, decoders, whatever).

I just ran the TLC SETI benchmark work unit... It took 4 hours 24 minutes and 18.61 seconds...

You can read how the benchmark works here...

And here are the results...

I honestly expected it to be much faster... :(

They say Linux is free, if your time is worth nothing... :mad:

I spent a whole day tracking down a mysterious bug that was preventing sftp from working... Eventually I found the answer here...

http://lists.suse.com/archive/suse-amd64/2003-Aug/0036.html

I'm only posting this so if I have this problem again I have the solution documented! :redface:

I am just curious, looking at the TLC SETI benchmark page using the link provided, it has one mysterious colum CpF with values ranging from 1.29 to 11.12 .

What is it and how is it calculated ? Is it some sort of efficiency calc ?
