MilkyWay_GPU - Almost There! Almost There in the BOINC Dictionary can mean anything up to & including 2 Years or more ... :) |

MilkyWay_GPU - Almost There! REmember Jerry Pournelle and his "real soon now" ... dating my self I suppose ... |

But isn't it just 'd/l html for your generic boinc website, change a couple of parameters [eg name from 'generic project name' to 'my project name'] and run installation script'? What speed 286 are they running this on? :) I must admit I had wondered about 'some academics thinking it would be cool to make a GPU project, and throwing together a bog-standard BOINC forum together and proclaiming - Almost There!' ;) Perhaps delivering a GPU-based project is a little more difficlt than envisaged, but it would be nice to know what was going on, if anything apart from the initial rush to set up accounts and teams. |

I was part of that initial rush. Managed to create an account on the 2nd or 3rd try, attached 5 PCs - 2 NV, 3 ATI, the PCs think they're attached though 'Computers on this account' shows none. Trying to find a team gives a stack of error msgs. I've d/l'd the FAH opti app to use up some GPU clock cycles while waiting for something to happen. I agree that occasional progress reports would be helpful... Cheers, PeterV . |

I agree that occasional progress reports would be helpful What, and waste 60 Seconds that could go to getting the Milkyway_GPU Project past the Almost There Stage. That could set it back another 2 Years if they did that ... :P |

I agree that occasional progress reports would be helpful Ha ha, I must admit I started this thread in the hope that 'someone in the know' might say a few words. But if you're busy then an "Amost Almost There (or not)!" would be nice ;) |

Well folks. Before you can run the script to make the project, you have to build the boinc system. Which, to say the least, is not pleasant on FreeBSD systems. Anywho, to update on the status, Travis is working on the GPU app. He has been working on it for the past 2 weeks. He has to translate the entire code from C into CUDA, which obviously isn't trivial. He told me the other day that he's got some functionality out of it but it's not yet complete. Dave Przybylo MilkyWay@home Developer Department of Computer Science Rensselaer Polytechnic Institute |

This is obviously of interest to the CPU guys as well since the migration of GPU to the new project should make things better here. |

That's cool Dave! No rush..."Did I just say that??..." We all appreciate the hard work from the team and Travis.. I feel like a kid at X-Mas time who cannot wait to open up the presents under the majestic decorated tree whilst on the outside the snow slowly set her white blanket upon the world... Martin |

Thanks Dave for this update. Waiting with interest, even if it is a few weeks yet. Go away, I was asleep |

Last word I got was that our expert programmer was waiting for the (un-translated) source code. |

Hmmm... so a couple weeks maybe. Still needs a test run when the code goes up and sort the bugs out when the server crashes ((predicting it will, ;p)). Doesn't expecting the unexpected make the unexpected the expected? If it makes sense, DON'T do it. |

Actually, having the GPU project up and running won't be an immediate help to the CPU side -- as the application will be a CUDA app and all the Milkyway GPU folks are currently running the optimized ATI application. The move for them will wait on the availability of an optimized ATI GPU application for the MilkyWay_GPU project. At a guess perhaps *sometime* in May. Until then, even with the release of the GPU Cuda - the ATI folks will be living on the 'CPU' work units.

Since Cluster has made the ATI app, that will be carried over and Travis is doing the CUDA app, so both will work. Doesn't expecting the unexpected make the unexpected the expected? If it makes sense, DON'T do it. |

He told me the other day that he's got some functionality out of it but it's not yet complete. Yep, I don't need a CUDA version. Just give me the C version of the Milkyway_GPU code as Travis promised 4 weeks ago. The CUDA code won't help me. Most probably it only makes it more difficult to figure out how to do the ATI port. I still hope the integration stuff is largely unchanged and only the parameter handling, checkpointing and so forth got a major overhaul to enable the larger WUs and different search algorithms. Then it may be possible to leave the GPU code untouched (only the C frame around it needs to be changed) which would make the port a matter of hours or a day if all goes well. To summarize it, I'm waiting for the (uncudafied) code! @ Travis/Dave: Do you see any chance to give it out before you finished the CUDA port? |

What I don't understand is that the Ati cards are running this project right now...Wouldn't it make more sense to start the new GPU project with them since they are already proven to work and add the Cuda in the near future ?? All your problems between gpu and cpu users are solved..........Doing it this way you are causing more problems because you are going to be adding more users (nvidia card) before you move the ati cards to the new project....... |

You are probably right. The only problem is that I don't have the code for the MilkyWay_gpu project to do the ATI port (a new application will be required for MW_gpu). As long as there is no application (and no WU for it and a working website), ATI cards can't start on the new GPU project ;) |
