Dead Things

Ticket ID: 1554 Priority: Low Please add ST 6x86 P166+ CPU info: http://www.cpu-world.com/CPUs/6x86/ST-ST6x86P166%2B.html If interested, maybe include the rest of the ST 6x86 series: http://www.cpu-world.com/CPUs/6x86/MANUF-ST.html Cheers!

Thanks Turrican!

Ironically, that particular SM board is indeed overclockable using a modded BIOS: http://hardforum.com/showpost.php?p=1038451753&postcount=1, just not with those particular chips. *fades back into the crowd*

Ticket ID: 1547 Priority: Low The Xeon X5460 appears to be listed on the site twice, once as a 3160 MHz part, and once as a 3166 MHz part (the latter of which is correct). Multiple instances can be seen in this list: http://hwbot.org/hardware/processors#key=s771 Processor info: http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon%20X5460%20-%20EU80574KJ087N%20-%20AT80574KJ087N%20%28BX80574X5460A%29.html

I know I'm bumping a really old thread here, but I was just wondering if you guys managed to figure this one out?

You betcha!

Good question. Long answer. Apologies in advance. Windows uses something called "processor groups" to accommodate systems with more than 64 logical processors. With 80 logical processors, the system would be divided into two processor groups comprised of 40 logical processors each. You can manually edit the BCD to change the processor group membership characteristics, but one thing that cannot be changed is the 64-processor ceiling per group. While this processors group implementation works for parallelized tasks, it does not work for symmetric tasks meaning that you're essentially limited to 64 cores in Windows for any one particular process. Because UCBench is actually really well-coded, each thread does not leave much processing headroom for hyperthreading, so it benefits way less from HT than, say, wPrime. As such, my score with 32 cores enabled and HT on was way lower than my score with all 40 enabled and HT off. I had some hope that Server 8 would do away with the clumsy processor group implementation, but that was not the case last time I checked. By comparison, Ubuntu has supported >64 threads per symmetric task since 10.04.

lol - My much-loved BE6-II finally died about two weeks ago! Go figure.

Great - have to redo 03. Unsupported SystemInfo Version apparently. Now I remember why I stopped submitting to the ORB years ago.

Thanks guys!

How do you upload a saved .3dr file using the free version of 03?

If I can find a little certain something in my storage locker this weekend, I should be able to submit a score for all four stages this month. Sounds like fun!

Gotta love the -0.3 on the XP. Tight!

lol - Little ol' me? Have you seen the unit prices on those E7 Xeons? ES was my only option!

Nice to see the new cascade in action! Although, I'm a bit sad you didn't upload a rig shot.

I thought the "bed-head" look was in these days?

Thanks! 20, actually.

No, there aren't. But, LGA 1567 supports a 3P config. This contrasts with earlier MP platforms that would support UP, DP and 4P configs, but never 3P, which I assume is why it's not one of the options.

I think the case of my E7-8860 rig, though, proves that there should be variable awards for top spots, as suggested. Having a rare machine like this and benching it should be worth something, but it should not be what is essentially a bye to first place in the EL.

I can't get wPrime to span multiple processor groups. So it's essentially limited to 64 threads in Windows - which is the max groupsize in Win7/2k8 and Win8. Still trying to figure it out but since Windows treats multiple processor groups as independent scheduling entities, it takes specific software code to make it work. I don't think wPrime will be able to handle it without code revisions. But as I said, still trying to figure it out.

Ticket ID: 1458 Priority: Medium The LGA 1567 platform supports the installation of 3x CPU sockets. Can we add this to the drop-down menu for number of processors? edit - Sorry, meant to file this as a feature request.

Figured it out! You have to use the -noaffinity flag (or untick the "Use affinity locking" checkbox in the advanced options). That's the only way unrar.exe will scale past 32 threads. So my command line is: "unrar bench -cf=ssse3 -cpus=X -noaffinity test.rar" where X is a number larger than 32. Thanks for all the input guys!

I get the same result on both 2k3 64 and 2k8 R2, and they each support up to 64 threads per processor group.

Unfortunately, no - it does not work. Even when specifying 40 threads, CPU usage maxes out at 80%, so only 32 threads are actually being used.

Thanks for reminding me Hondacity! And looks like dhenzjhen ran into the same 32-thread ceiling that I am running into: http://hwbot.org/submission/2230518_dhenzjhen_ucbench_2011_4x_xeon_e7_2870_1999_mpt_score/ I guess there's no way around it. Oh well - pity, I was just starting to enjoy UC Bench.
