Re: Utilize GPU for processing power (a thread this forum):
-------------------------------------------------------------------------------- If interested in the difficulty to convert these science applications, .... The idea has been planted and as posted elsewhere on this forum, WCG is looking at the feasibility of doing something with the PS3. cheers Go to the search box and search for GPU for more. Here is one of the latest only one month old on one net site: Cross references to WCG forums pages for your pleasure: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=10006#78011 http://www.tomshardware.com/2006/11/08/geforce_8800/page11.html Go to the above URL for missing images and other text. Darren E. Polkowski November 8, 2006 13:50 (missing paragraphs) Last but not least on our tour of G80 enabled treats is what Nvidia calls Compute Unified Device Architecture (CUDA). This was one of the things that blew me out of the water. For years there have been enthusiasts and academicians looking for ways to do more on powerful parallel processors. When a Beowulf cluster was out of reach for the budget conscience, people started looking to graphics cards for more horsepower. Now programmers have the ability to create programs that scale on both the CPU and the graphics processor. Protein folding at home and other applications requiring massive amounts of computational power and precision will fall in love with (sic)CUDA. Not only can CUDA help invent programs to solve the world's ills but it can be used to blow things up better or simulate other things like volumetric fluids, cloth and hair. Effects physics and even other game play features could be potentially ported back to the graphics processor via CUDA. "An entire SDK will be made available to those whom it should go to. If you are looking for a cure for cancer or ways to help mankind, Nvidia said they are willing to help you out." Author's Opinion: .... C+ compiled programs running on the CPU in conjunction with the parallel computing power of a versatile shader core with Stream Out is beyond comprehension as the possibilities are endless. I can't wait to see the community's implementation of such a wonderful tool. |

Hey PaulT,
----------------------------------------You can signify quotes by selecting the snippet(s) and hit the Quote button up top. If interested in the difficulty to convert these science applications,...... The idea has been planted and as posted elsewhere on this forum, WCG is looking at the feasibility of doing something with the PS3. It is customary to provide a link to the other thread in the forum, which helps to keep it together: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=10006#78072 similar to CPU special feature recognition (SSE, SSE2, MMX etc) to ensure that in a quorum all 3 work units are calculated absolutely identical, the same will go for GPU's..... so many video cards, that will be combined with so many different CPU's (BOiNCstats lists over 800 different once used of latter), that the matching / distribution process will be a serious headache in it self.... that's why F@H only uses 1 specific card to test it all..... and still using 50% of the CPU time. I think the waiting will be still long ways, except maybe for specialty projects.... i wont be waiting though :D Cheers

..... so many video cards, that will be combined with so many different CPU's (BOiNCstats lists over 800 different once used of latter), that ,,,, Cheers I understand your point and the gross problem. What I don't know is if the increase in efficiency of using a single vendor's card to output. Some analysis have mentioned that there is going to be a melding of CPU and GPU into a single unit. Sort of like a dual core (X2) package. One core with a CPU and the other core a GPU. Or, a single die combining the CPU with GPU. I would think a really smokeing package for computations. Hpw about a 4 core chip that is broken down to 2 CPU;s with 2 GPU's or a 3 and 1, or a combo chip with a core CPU, etc. Note the purchase of ATI by AMD. Someone must be thinking in this direction. Whoever gets one of those fantacy baby's out to the retailers and mother-board guys, they could swoop a good piece of the market. Just think of the PR one would get even if limited quantities. You may not have to wait. Could be one in a lab right now waiting for engineering to design the fab processes. Anyway . . . . . hope is eternal. :>) [Edit 2 times, last edit by Former Member at Dec 1, 2006 11:26:10 AM] |

Hello PTabolinsky,
Unifying the CPU and GPU is probably going to happen. It is suspected that the real reason that AMD and ATI merged is preparation for this future. Once you have 16 cores on a chip, it makes a lot of sense to have them running the graphics. If Intel came out with an x86 upgrade like this, AMD would be killed unless it had some in-house graphics expertise. But there is a lot of development needed. Note that Folding@Home can only run a subset of their computer problems on the GPU. Lawrence |

... Folding@Home can only run a subset of their computer problems on the GPU. Lawrence Well it seems that I can go o further without looking at the problems and what tools are being used. So. . . ... I'm off to exploration of same. Hope I can get a handle on the stuff. Hello SSearch, Plunk, and other engines. I hope to be back. :>) |
