V24.12 special benchmarks needed

[delta_t]

george,
i removed the file in my above post because i forgot to put allbench=1. here's the results again. fullbench=1, allbench=1.
ibm thinkpad t42p, 2.1 ghz pentium-m (dothan) w/2mb cache.

I can get you a Sempron 3100 in the same mainboard with 512MB of main memory tomorrow.

As requested another P4 Prescott with 1MB of L2 cache. This one is identical to the other except it has an AGP video card instead of PCI. Both dual channel Ram with Geil PC4000 DDR.

Here's another P4, still with 1 Mb L2 cache.
Side conditions: Win 2003 EE SP1, HT enabled, plenty of RAM, dual-processor machine (with the other cpu performing LL-testing)

Here another P-IV 1Mb, had started it already so I just post it even tough there are already some more results.

It's a HP DX2000 desktop with onboard vga.

I've benchmarked mobile P3 1000. The results are fairly consistent exept for the 1024 FFT which gives strange result - I have verified this twice and results are the same.

Good catch - it's a bug!

Does it affect x87 code-path only?

Yes, there is a bug in x87 1024K FFT sizes on machines that do not support prefetching (P2 and earlier). It might affect SoB, but I think they are using 768K FFT sizes right now.

But P3 supports "prefetch"... so how come the error became visible
