Sekerob, thank you.
----------------------------------------You're right - have not read carefully that post. Anyway I wanted to buy a new ATI card, I think the time has come :) Any info about compatibility of newest ATI cards? (I mean 79xx and 78xx)

Well, the beta runs on 7750 (mine) and 7970 (teammate's), so I guess it's working. Same like everyone, some valids, some "too late's" (o.O), some inconclusive results..

Can you post the time completed from the 7970? Would like to compare it to my 6950.

EDIT: I looked in BOINCTasks History and all three seemed to have run in 5 minutes clock (CPU & GPU) and used 0.79 of CPU and 1 GPU. Still too early to tell anything. EDIT 2: On the CPU test side, I am getting a consistant 26 BOINC credits for 1.1 CPU hours (i7 970). That seems to me to be an equitible spread of BOINC credits between a CPU job and a GPU job.  Credit spread may be ok but how will time allocated to badges work? The two GPU WU's I completed today finished in 0.02 hrs CPU TIME and an unknown clock time (lets assume 5 mins as per DM). This would give me 288 GPU WU's completed in a day but only 288 x 0.02 hrs towards badge recognition  If I ran CPU WU's only I would run pretty close to 1:1 ratio of CPU time to clock time and thus have virtually a full days work locked up in pending jail  Or am I missing something here??

Yes, you're missing something. The Elapsed time is supposed to be the measured time for statistics, so if it took 6 minutes from start to finish, then 6 minutes gets credited. Unfortunately we can't say "same as at other grids" as other grids don't keep time beyond where the credit [points] has been computed. In that WCG is pretty unique. This is assuming an unthrottled host... one that is set to use 100% CPU (aka GPU time).

I configured six of my machines to receive GPU workunits.
----------------------------------------Five machines use the Nvidia GTX580 and one has a GTX480. All with the latest 296 series driver. These are all Cuda 2.0 or more, so they should be ok. Let's see if I can grab now a few of these Beta GPU. For the moment I got 30 WUs but of the CPU type. The were finished in about 1hr and 15 minutes. It would be interesting to see the difference. WCG please send a few of them  thanks. |

Don't forget to confirm you've got the OpenCL part installed. The GPU-Z tool will confirm, bottom left. Don't think that at this performance we'll ever going to see a CUDA specific GPU project at WCG.

SekeRob,
From my limited computer background, I get the impression that AMD/ATI is "better" as single FPU projects (basic numbers), while NVIDIA is more adept for double FPU projects, which are more complex. So for "basic" (not being used negatively) projects, yes AMD/ATI is better (PrimeGrid, Bitcoin are my two best examples.) While NVIDIA's seem to be the prefered brand by scientists for molecular research and other applications that require more oomph. Like I said, I really don't know a lot about the differences in programming/design, but I do know that even though I read a lot about how good AMD/ATI's cards are, it seems to me that many new games, Grid apps, and supercomputers being built revolve are NVIDIA's design for some reason. If someone could enlighten me on this I would appreciate it. Crunching on...... |

I say this of not expecting CUDA as it is going to exclude a very big portion of the volunteer community if that criteria was set... which is why WCG went for OpenCL, and it so happens that HCC is an integer computing science. Who knows what the future will bring. Read last week that NVidia joined an open source Linux consortium, so who knows will CUDA become less proprietary.
