HCC GPU Launched.

[[XC] Oj101]

I'm running a GTX 580 SuperOverclock which runs at 855 MHz instead of the stock 772 MHz, and I'm averaging 3m14 per WU. This task definitely favours AMD.

Seems like it does. Or at lest the 7xxx series. Still, only 3 minutes for a WU is crazy good and a lot more work will get done. In the end this is what is most exciting to me, the huge amount of extra science this brings. About time too! I've always kept my eye on F@H specifically for the GPU support.

Use at your own risk. app_info only usable for HCC GPU only.

It works for my 5850, but now it only uses the GPU. No work for the CPU. And it went up from 3 minutes per WU to over 5 minutes.

Depending on how much over 5 minutes you are still getting a pretty good increase in overall throughput. Each GPU + CPU (including HT or not) + OS configuration needs to be assessed to find the overall benefit.

Something seems a bit off with some of those numbers. The 7870 has effectively double the SPs as the 7770 and 25% more than the 7850 and half of the 7970, yet the numbers don't appear to be reflect this, or there are variables we are unaware of.

Right now that 7870 card is temporarily in my Work PC (see sig below for specs). Not sure of that matters, but it will be going in my 2600k rig this weekend hopefully. Now, I am doing WU anywhere from 1:32 to 1:57, so much better than the 2:06 I was using yesterday. Also, it never goes above 84% GPU utilization.

So we a looking at a range of 172-217K WCG PPD at that rate depended on where you look. I say split the diff and call it 196K PPD WCG.

I'll have to see if putting it in my main 2600k rig improves things.

Anyone know if the 285 works on this?

Anyone know if the 285 works on this?

You mean GTX 285? It should as my GTX 260 works fine.

Just RMA'd a 5870 and got a 7870 OC back. Might have to put it through its paces instead of selling now

In the meantime.. let's see where this gets me:

Personally I think you should send it to your good buddy Dave who REALLY needs a card...

[jcool]

Something for the stats:

GTX 260 (600/1300/1100 core/shader/mem) takes roughly 7 minutes per WU, GPU load between 93 and 98%, 1 dedicated CPU thread full load (Intel Hex @ 3.6Ghz), BOINC 6.10.58

yea, BUT assembling a 3770K and 2600K and only have one 5870 card ..I do NEED another card so hush your mouth

Hey jcool, nice to see you..
Ok, I'm off, just got a call for some work!

[masterg]

Im using a 5850 and a 5870 averaging 3 minutes a WU. after like 2 days, my output has double so far and increasing by the minute

I have a 4850x2 and a 5830 lying around i could add to the mix if my PSU's could handle that kind of load

In the meantime.. let's see where this gets me:

Since I made that post, I have 4 pages of Pending WUs. Completion times vary between 3.5 and 4 minutes. The cards clock themselves up to 3D clocks when in use. What really surprises me is the low heat output and power consumption. I KNOW what these cards will do when pushed to the absolute max.... instead of breaking 1KW of total system draw, I'm seeing 600W from the wall with a fully loaded 990X. Also, despite what others reported, I do notice GUI lag, but nothing serious. Aero effects are a little laggy, but the input never freezes fully.

EDIT: Not sure why the board software keeps resizing my image for me even though it's hosted elsewhere, so I'm just going to link to it.

At the moment it is taking between 5:10 and 5:30 for a WU to complete. This afternoon I did see some below 4:30. At 5:30 per WU that is 17k boinc per day.


Is every one getting what they claimed for a completed WU?

[Mydog]

I'm getting two 460's and one 7970 today from a buddy, he also has 10 GTX285's that I can take but should I??

Need to check my PSU status here I guess, power consumption will go through the roof here

[hendermd]

I have been playing around with cpu/gpu settings (3770k/HD 7770) and have these results,

2:19 to 2:55 min/wu - at stock cpu/gpu settings
2:10 to 2:40 min/wu - with gpu oc'ed 1100/1200 from 1000/1125 (core/mem) [144 watts total]
1:52 to 2:34 min/wu - with gpu oc and cpu oc'ed to 4.2 [154 watts total]

[bluestang]

@herndermd...what driver you using again (I'm on 12.8)? And what program for OCing? Have you had any "grey screens" with your OCs? I've been trying to OC my 7870 and keep getting solid gray screens eventually even if the OC is a little, like 1100 core/1300 mem. Stock is at 1050/1250.

I calculated the average CPU time for all the WU's that have been validated by now (46 WU's) for my GTX 260 (192SP) + 3770K at 4.8GHz.

.........

Average CPU time was 0.1208 which would mean a WU on average takes 7 min and 40 sec.
It can do slightly more than 8 WU's per hour which means it would do ~45000 WCG points per day.

Oldchap, how did you calculate from time per WU to WU's per hour? I seem to be getting slightly different numbers and probably forgetting something stupid

I am taking the runtime from the machine.... I watch it run for 20 seconds then it starts to ramp up through the percentages to 99.415% then run on cpu for maybe 50 is seconds on this q6600 that I am testing on. The time I take is that showing whilst it is uploading. I then take an hour and divide by the average time figure of a number of wu's to get wu's an hour etc.

The last few have seen a variance in completion times between 3m 01s and 3m 48s with most toward the lower figure so I choose to say 3m 20s for mine as a reasonable average figure to give folks a good feel for what this card is capable of.

Looking at the numbers produced by these I hope we will be able to decide if it is worth selling some cards and buying others or sticking with what we have as well as seeing which new purchases might be the most cost effective

As for running cards at full speed with 2 wu's running.... I don't think I want to go there purely for power cost reasons just now.

Chart update soon

@herndermd...what driver you using again (I'm on 12.8)? And what program for OCing? Have you had any "grey screens" with your OCs? I've been trying to OC my 7870 and keep getting solid gray screens eventually even if the OC is a little, like 1100 core/1300 mem. Stock is at 1050/1250.

I have catalyst 12.9 beta and using sapphire Trixx to oc. Currently 1200 / 1400 at XFX 7870. Running fine no "grey screens" or other problems. CPU 3930K ocd to 4900Mhz. Average WU time 1.30 - 1.40 minutes

[Vinas]

First WU took 4:01 minutes and the second GPU WU took 3:43 minutes... Dual 5870's are pretty darn fast at this!

I'm on 12.8 as well, my card is a HIS HD 7770 and I used the iTurbo program that came with.

Ok, here are my findings so far, I'm sure many of you have noticed the same:

There is a "GPU-part" and a "CPU-part" in current HCC GPU WUs.
When the WU starts, GPU usage goes up (90% in my case), and the WU computes to 99,5% finished with no real CPU load (getting 2% on a HT-enabled Dual Core). Then, the GPU usage stops completely, and the CPU usage starts to hit max. for 1 core/thread until the WU shows up as completed, and the GPU starts its next WU. It almost seems like the CPU has to convert the GPUs result to a CPU result, or maybe check it for errors, or something.

What this means:

A faster CPU will improve total computational time of GPU WUs!

-------------------------------

Results for single 5870 (900/1200) and L5630 @ 2.8Ghz using Catalyst 12.8 and BOINC 7.10.28 on Win7 x64:

GPU time 2:15-2:30 + 45s CPU time = total time around 3 minutes 15 seconds

i would say definitely don't purchase new gtx 460 for the project.. know limitaion in the arch makes them only 1/2 or 2/3 of the shaders useable for CUDA tasks (can't remember exactly, I bet snow crash knows..)

edit: boinc knows that the GPU tasks will take 1 cpu core and reserves a core for them, so you can still set 100% of cores. notice the task says "1 CPUS + 1 NVIDIA GPU"

Didn't realize that, but you are right - scratch that then.
For now it looks like the HD7770 is the card to buy, although I dont get how it can be faster than a 5870. In every other application, be it GPGPU or not, the 5870 is twice as fast. Bitcoin, which is probably the best OpenCL benchmark there is, has the 5870 at ~80% higher performance. Hopefully with future optimizations, the performance of present and past top cards will be put to better use (7970 apparently doesn't go over 60% usage either)
