Sure, a GPU doing a VLAR might be better than an idle GPU (depending from your point of view), You do realize you just contradicted yourself? Reread your last line. I don't care how others run their pc, so long as they are not aborting work that does not does not cause errors. Just because it takes longer is not an excuse to off load work units onto other people. That's cherry picking. |

Every time VLARs are discussed I remember The Attack of the Killer 58.7s. In that late 2006 time frame with only CPU crunching and coarser chirp resolution, that was the granted credit rate for VLARs. Conceptually, assigning work in a manner such that each host is most productive is obviously desirable. The .vlar exclusion for CUDA does align with that and is definitely needed as long as the 6.08 and 6.09 stock applications are in use on older CUDA cards. My impression is that when SETI@home v7 is released here, both CUDA and NV OpenCL implementations should be capable of doing VLARS without excessive screen lags, etc., and with less time penalty. An adjustment of the basic splitter estimate could be used to better balance credit grants. The fact remains that VLAR tasks are harder to divide into small enough parts to take full advantage of the parallel nature of GPU crunching. Newer GPUs do have the capability to be subdivided so that only part of the GPU would be working on the least divisible parts of the task, but that's another layer of software complexity and there would be issues with validation on result_overflow tasks. That brings this discussion back toward the "Server problems" subject area. Joe |

Please don´t missunderstud what I and Richard says, SETI is a project that is spected to runs DECADES before any spected success could be achived (unless of course our little green mens give us a hand), so "fast or slow" is relative to that, the difference from a 12 min WU (GPU) to a 1 1/2 hour (CPU) makes little difference to the 50 Years or maybe more project. And when we (or our children, or our chilren's children) DO find the elusive little fraks, I'm sure the project will have all the funding and support it needs to last another 500 years. You know, so we can find the next race, and then the next one, and then the next one... :) |

Blocking it for hours or even days with a bunch of VLARs might indeed lead to less job done at the end of the day/month/year/whatever. Don't know how long your GPU needs for a 0.44 WU, but idle GPU for 5 minutes (until the next request, which might give you something else than VLARs) might be indeed better solution than crunching VLARs, just do the math, you have the numbers. So yes, an idle GPU for a while might be better unless the servers would send just 1 VLAR in case they have nothing else and the GPU is idle. What's wrong with that line? If the servers were able to react like that, we could consider doing that in case of "VLAR storm" which could keep the GPU idle for several hours. I was not talking about filling up the GPU cache with VLARs. I don't care how others run their pc, so long as they are not aborting work Other people might be very happy to get those WUs, my AMD CPUs love VLARs for example. But since the project won't be sending any VLARs to GPUs anymore, at least not on purpose, we don't need to worry about much cherry picking. . ![]() |

Last night (22Aug2012) I reported an AP and got 10 MB shorties. Shortly after midnight PDT (0730 UTC) today I got 30 more of them. Just reported 6 MB shorties and got 2 mid-range MBs back. No time-outs or failed scheduler requests in my event log. Things might be settling down. Donald Infernal Optimist / Submariner, retired |

Seems like our wingmens take few days off, normaly Pendings/Validated = 2x, to much pendings = to low RAC!. Now = 12282WU wonder to see when the number stop growing. Yeah, I'm actually starting to realize what you meant about pendings piling up. I've never had so many, but then again, judging by the ones that have validated it looks like they're mostly going to be shorties. But still, a ton of pending WU's....holy moly! ![]() |

Huge Panic. The panic thread is now way above the 200 posts, where arkayn usually would start a new Panic Mode thread. This thread is getting too big for my 300 Baud modem..... What to do, what to do? :-) Too much hormone treated meat. Too much Monsanto veggies. Too old and outdated constitution. A crazy problem, as you Yanks use to say...... There is no God, and God never existed. |

I don't think we need the 200 posts limit since the forum software finally arrived in 21st century and is splitting the thread to pages. Don't see any issues so far and I'm also only on UMTS, usually down to 64kbit/s. . ![]() |

What to do, what to do? :-) go to your "community preferences" and set the maximum number of posts per page to something manageable on your machine. ![]() |

Ok, I think I will have to stop using my Swedish, and/or English type of humour. Seems as if only people from England (Great Britain), and Nordic people get it. Be serious Sten-Arne, be very very serious. Too much hormone treated meat. Too much Monsanto veggies. Too old and outdated constitution. A crazy problem, as you Yanks use to say...... There is no God, and God never existed. |

Now you see what i say, is not just about RAC is about the big pendings number (still have more than 11K). All the new work done have the target of Oct so may of the wingmens must still off dutty. ![]() |

Sorry if post is semi OT. If anyone doesn't get enough tasks due server problems/slow downloads, LHC@home has over 400k units waiting. |
