YES that IS the advantage of having multi GB of memory on your gpu, the ability to run several workunits on one time! I have 1GB cards and still run two units at once on MilkyWay. Doing so REQUIRES some tweaking and can SERIOUSLY overheat your gpu, so you MUST make sure to keep a close eye on it! Running multiple workunits at once is NOT always a good thing though, sometimes the gpu needs to share resources and in those Projects running multiple workunits at the same time is not helpful. Most people just try it and see if it helps or not. Here at WCG though since we currently CANNOT chose between running cpu or gpu units, it may not be helpful. You can run cpu only units but currently there are no options to run gpu only units. I don't know about MilkyWay, and was just referring to POEM and WCG/HCC. HCC is taking only 27 MB of my HD 7770. Overheating is another matter and not related to memory of course. |

Sek, am crunching HFCC. I added HCC so I could get the GPU wu's and see both non GPU and GPU wu's get downloaded. After reading the posts to not select HCC but insure selecting the option to use GPU if available, which I do have ticked, I deselected it last night before hitting the hay. Woke up this morning and only have HFCC crunching. Kneed responded to me last night stating there is no separate option for HCC GPU but they are looking into this for the next project. Yes, saw that, but the impression was given that tricked worked... if it does, you proved it to be not reliable. Thx. edit: Asked for someone to draft a workaround FAQ, and here comes knreed, who did: https://secure.worldcommunitygrid.org/forums/wcg/viewthread_thread,33981 [Edit 1 times, last edit by Former Member at Oct 11, 2012 2:57:30 PM] |

All I'm going to say after seeing the effect of only 12 hours is WOW! OMG! ..

GPU crunching effect in results, last column:

Will give this a shot and see what happens. Should know in about 20 minutes.

Think WCG would be looking for more projects to run instead of projects waiting in line to use WCG. My next build will be a cheap quad core that can utilize multiple GPU's. Best bang for the buck IMHO.

It's been explained how to get there [HCC on GPU only, other WCG CPU sciences only on CPU]. Several have repeated how to do it, such a rilian, and others have responded that it works for them... Choose e.g. FAAH+SN2S and CPU-Yes+GPU-Yes [do not select HCC. The feeder priority [speculation] seems to work so that the CPU gets fed with FAAH+SN2S and the GPU has little option, it fetches HCC. Those that select only HCC and CPU-Yes+GPU-Yes are likely to get both [if their hardware meets the requirements]. Just highlighting in case the workaround was missed. This does not work for me. Maybe you also have to have selected "If there is no work available for my computer for the projects I have selected above, please send me work from another project."?? I do not use that option. |

Thats an understatement. Just imangine if all projects went GPU. Think WCG would be looking for more projects to run instead of projects waiting in line to use WCG The majority of users will have their systems bog down, start complaining about GPU, quit crunching WCG. More complaints that their GPU card is not supported. More accusations and demands by the users. Old computers no longer supported. 32 core computers will do a single WU at a time on their GPU card. Frustration will then abound. It will be great.Once we get to that stage, then the science projects that cannot be run on a GPU will be ignored, WCG will no longer service as many projects and then has no value to the scientific community and dies a horrible death. Great planning on your part. LONG LIVE THE GPU! |
