If there will be an OpenCL app for CPU's, it would make sense to beta that first. Why HCC already runs on CPUs? If the OpenCL app was not comparable with reliable results, they wouldn't be moving forward to beta. Except they're moving towards a GPU beta, not an OpenGL CPU beta. Different animal. Even if the code was general enough to run on either, it's not worth the effort if they don't make use of the available optimisations for GPU which would require ANOTHER beta before going into production. I'm keen for more beta time for my badges, too ... but there's no point wasting time running beta tests for a client that's not headed for the production environment.

Unfortunately there are tradeoffs for all 'generic' software. Optimization will come later and my money goes there, but for now, going 'generic' makes a lot of sense when just starting out -- specially when just starting out. Come one, come all... Have a GPU? Then you are good to go... now! (and not tomorrow while awaiting fine-tuning of the optimized implementation).; I hope the GPU application happens soon to put an end to all the speculation.....  crunching, crunching, crunching.

Soon is good. Well, folding cannot be run under boinc, rosetta will not use gpus, gpugrid does not support low end amd gpus, and poem is currently the only option. It would be nice to have a 2nd boinc project on low-end amd gpus :) |

It would be nice to have a 2nd boinc project on low-end amd gpus I don't have very much experience with GPUs, I purchased two 80 stream ATI video cards with passive cooling about a year ago, but when I read the comment above I went a Google'n. This site seems informative. By "Benchmark" sort there are 5 nVidia and 5 ATI in the top 10. By "Power" sort" there are 7 nVidia and 3 ATI in the top 10. So to me it looks like nVidia use more power to get better benchmark results. For a device that's crunching 24/7/365, I'd rather have an energy efficient one than a power drain.  Oh, back to "low-end amd gpus" ... By "Benchmark" sort the bottom 10 there are 7 ATI and 3 nVidia. Edit: spelling, darn auto-correct.  [Edit 1 times, last edit by BSD at Dec 31, 2011 4:22:13 PM] |

Collatz is fine for both NVIDIA and ATI....it is where I am comparing the 2 waiting until I can compare them at WCG before deciding which way to upgrade.....

----------------------------------------A few years back I was an Intel & Nvidia fanboy. More recently I tend to buy amd for their graphics which have a higher theoretical performance, but a lower gpu % utilization. @mikey159b I was referring only to medical projects :) |

If and when POEM supports NVidia cards there will be a project that supports low end NVidia GPU's, as almost all NVidia cards are OpenCL capable, including G80's.
This is not true for AMD. Only 5000 series and above are fully OpenCL capable. The 4000 series only has Beta level support for OpenCL, so some GPU's might not actually work (the two 80 stream processor cards for example). None of the 3000 cards are OpenCL capable. So even when WCG has GPU projects, there still won't be a Bio/Med project for all small/old AMD GPU's. Unless there is an ATI stream based Bio/Med project, and soon, there never will be support for these cards; time moves on fast and in a year or so few people will have 3000 series cards. |
