Anyone with a quad and a few minutes of CPU time?

Hi Martin,
3-3-3-8 latency!!!
I would be quite interested if you could post the FritzMark
(standalone program: http://www.jens.tauchclub-krems.at/dive ... chmark.zip )

Greetings Ernest,

If you are interested in computer hardware, here is the list of my components:

1 x Western Digital Raptor 74 GB, 16 MB Cache (Harddrive)
1 x Western Digital Raptor 74 GB, 8 MB Cache (Harddrive)

Computer has run 24/7 since I put it together at the start of October, and has not crashed yet. It runs at 3402 MHz.

Very nice Martin. Why won't you put those 2 Raptors in RAID 0?

Diff. Buffer but should still work faster.

Very nice Martin. Why won't you put those 2 Raptors in RAID 0?

Diff. Buffer but should still work faster.

I'm not using those disks for tablebase access. I have a seperate flashdrive for that, which is proved to be faster than a single raptor.

The raptors are only used for storage and operating system, but since they are so small in terms of capacity, I need both of them right now as separate disks.

I do think the Raptors in a RAID 0 configuration could give the flashdrive a run for the money, though.

We did some research on this in CCRL a while back. I can post the results here (Shaun Brewer posted this elsewhere as well I think), so you can see.

Ahh I see. Very nice.

I'm personally waiting on those super-fast SSD's that should come by later this year with lower prices.

Or maybe the Fusion IO.

Here are the results for Hamster non extreme version. Unfortunately there appears to be a problem when I try anything above 4 threads. Hamster just ends without any error message.

Ah, a bug it is! Hopefully (it's difficult to test this without the proper hardware) it is fixed here:

[Spock]

On my slow-ish quad Opteron (your original exe)

1 CPU - about 450
4 CPU - about 1570

Scaling similar to Intel actually

[Alessandro Scotti]

Thanks Ray, it's a good result and I have some hope of improving it a little!

[Tommy]

Very cool, looks like all 8 wheels are spinning!

Your hamsters in action...

[Alessandro Scotti]

Hi Thomas,
thanks for the feedback and glad to know it finally works!

So the speedup on 8 CPU is about 5.1, not the greatest but not bad either, in fact I'm quite happy with it, thanks again!
