What is stopping Nutritious Rice for the World form doing CUDA/GPU enabled builds ?
I would like my Nvidia GPU on my new Mac Book Pro working for the Nutritious Rice for the World effort. I've compiled the CUDA 2.0 packages available from Nvidia on Mac OS X, and the they compiled without any problems what so ever. I've read over in http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=26175 that the WCG is currently stalling the process. - Are you pushing them on it, so that it's not just users directly Just think about all the computer users/owners out there with GPUs in either there PS3 or Nvidia who are turning instead to SETI or GPUGRID instead...and all that processing power that could be put to used to improve rice for the world...BTW... thanks for letting my iBook help out too with this effort, it's great to be able to put it to use! |

There's a thousand reasons why it is not (see the thousand threads at WCG for discussion). First reason is, the science application might be wholly unsuitable for porting, needing allot more precision than GPU's can offer. Then there is the time and resource factor. Another major reason is that WCG as of yet thinks that BOINC is not mainstream ready for GPU crunching... you'll for sure know when GPU crunching is running. It impairs substantially and if it does, not exactly out of the box and WCG does not want anyone to unwittingly walk into this and be disappointed, to walk away from crunching completely.
----------------------------------------sorry PS: Would you please delete your other double posted message in this forum. Added: As for your Suggestions and Feedback thread, same answer. WCG targets the Help Cure Cancer project as the first to get ported, as and when the science software conversion is done and based on a client that does provide unobtrusive crunching.

Those are some reasonable "might be" and "could be" reasons. Thank you for thoughts on the topic. I would still like to read a final answer on this from WCG/NRftW still.
- Are you speaking officially on behalf of WCG/NRftW, just for good orders sake? P.s. I removed my first post, my mistake in trying to go back up a page... |

CA's don't speak 'officially' since we're not employees, but still we've been appointed to CA for a reason, and no those are not might be / could be reasons... those ARE some of the real why's, already shared by WCG techs directly with the volunteers.

I can't speak for what's happening on the wcg side of things, only from the point of view of the protein folding algorithm.
I have looked into gpu acceleration of the process. It is not quite a simple as you might think. The calculations can indeed be sped up many orders of magnitude. However, with the current algorithm, the limiting factor appears to be the rate of communication between the cpu and gpu, which is not uncommon or unexpected. The process has already been optimized for cpus to minimize expensive calculations while not worrying so much about memory bandwidth. While it certainly is possible to get very significant speed increases with the current algorithm, the gpu firepower is better exploited by allowing the removal of the compromises in the methodology that needed to be made so that it runs as fast as it does on cpus. I can only imagine the headaches on the wcg side of it in making sure that any gpu-enabled project runs properly on any combination of gpus and cpus... Hong |

thank you lhhung for the information
----------------------------------------it is always nice to see someone behind the projects answering questions that come up. and i would also like to thank Sekerob its nice to see the comunity advisers out there since they normaly can answer many of the questions on there own time alowing the people on WCG and on the projects to work on them instead of answering alot of questions that myself and others seme to come up with. when i see Sekerob's answers i normaly know its likely the correct one  |

since my last reply i found an answer of sorts in sugestions feedback
----------------------------------------http://www.worldcommunitygrid.org/forums/wcg/...276&offset=0#lastpost We're still working on it although it's not super high-priority for us. We were close to having a plan in place for going only with nVidia but now we are also looking at OpenCL. The only project that is feasible to run CUDA/GPU is Help Conquer Cancer. |

I'm a big supporter of GPU crunching (GPUGrid), but I always have my suspicions when someone comes into a project complaining about no CUDA support when they have never crunched a single workunit for the project.

out of curiosity ... what is your suspicion? That they think that CUDA is more important than the science we are working on |
