Each Graphics Card I have is on the "Excluded" list, so I won't GPU'ing any time soon, I can't afford to replace 1, let alone all 4, their not cheap (I would have thought my newest systems card would be okay atleast, seeing as I upgraded from the card it originally had, but no!)

I passed 72000 results for the team though.

If you allow it to use your GPU..... do you get double the runtime?

on my quad core, 4 still show as running (as expected) but two of them have (running 1.00 CPUs + 1.00 ATI GPUs).

Afternoon all,

Good to see a couple of members restarting their crunching and hopefully others will follow.

And I did manage to pass my first 100 days worth of RT for the team with the last update.

Crikey, only 3 or so minutes for a GPU HCC unit? Is that all they really take to complete

There's been a request for someone to write a FAQ for HCC GPU, til then it's a case of piecing together bits and pieces from various threads, and I'm no expert so with that important caveat:

I think Mike is right. Total runtime per device will be largely unaffected, but Points and Results will increase substantiallly possibly by as much as a factor of 10.

I'm hampered because I haven't received any GPU WUs yet - an unforseen consequence of having my cache set at 10 days to ensure I snagged enough HCMD WUs to make Ruby. Hopefully the lunchtime update will confirm that I've crunched sufficient (Completed+P/V) that I can abort the rest and return to normal.

The UK team stats for the 7 days to 9th Oct show that HCC accounted for 25.21% RT 26.56% Pts and 61.99% Res. The GPU WUs arrived too late in the UTC day (10 Oct) to have any discernible impact. (They're grouped together under HCC with CPU WUs so its not going to be easy).

Factor of 10 is maybe a bit excessive. I've browsed some more and *8 seems to be quoted for recent, high-level machines. Truth is, only time - several days - will tell.

knreed WCG tech has posted:
As far as the impact of GPU on the project, here is data on success results returned in the past 2 hours:

%_results  num_results  platform
37%	        18768	   CPU
36%	        17877	   ATI GPU
27%	        13420	   NVIDIA GPU

If we estimate 24 hours of results for CPU we get ~220,000 which is the same pace that we were previously completing results for the project.

If we estimate 24 hours of results for GPU we get ~375,000.

That is a VERY nice increase in work accomplished for the project.

Power consumption went from 200W to 270W and turned my machine into a space heater. That 70W boosted throughput 2.4x.
