Cobblestone machine benchmarks would be with both numbers as close to 1000 as possible.

FP: 1000
Int: 1000

Anyone got one? Provide a link to its info page.

I think Benher is working on "the average Seti work unit" and maybe a machine that a real even integer/floating point benchmark would somehow help him.

I'm just guessing, so maybe he will enlighten us (me). His threads have been quite interesting and it's the sort of thing I like to see in Number Crunching (there's too many topics here that belong in the "questions" forum, and yes, I'm a violator too)!

Hi Ben!

All my (quite different) machines are lower in FP than in INT performance.
This might have to do with the the different operand sizes
of the integer (4 Byte) and the FP (8 bytes) operands used in the benchmarks.

You might try compiling a client with a single precision FP benchmark.

Hi Ben,

after some fiddling around with grep I came across this one:

Regards Hans

EDIT: Some more, with more results:

A 2.4Gig Xeon running on a MP board seems to be what you're looking for

I dout that he will enlighten you. The cobblstone is becoming such a flop as far as crediting goes no one is going to want to take responsibillity for coming up with the Idea. I hope he come through for you.

You can see original boinc, slightly optimized boinc,
Boinc compiled with Intel C.
I guess machine was pretty loaded three days ago to get almost 1000/1000 ;-)
Kernel was upgraded a month ago.
Frankly, I've been a bit upset by Wintendo boxes out-cobblering me,
after considering adding "--mips-factor 1.2" option to multiply everything with
1.2 (sin), my collegue managed to compile local version.

To comment:

It is good idea to do fairly benchmark. If we have to be pedantic, some
filtering/averaging can do great. Maybe in version 6.3 ;-)
This is proper way to smoth sinners (see above).

Simpy by comparing RAC on different boxes I can get feeling on speed and
non-boinc load.
By checking work done in last few days I already discovered problem on one PC.
Boinc is a kind of SMTP as well.

Enjoy,
Iztok
