Have now taken to manually aborting: When I checked, you were aborting v7 cuda23 tasks on your GTX 295 host, not your GTX580 hosts, and if you were then there would be a scheduler Bug because the Cuda23 Can't be run on Fermi's and Keplers. Claggy |

Before we switched to v7 we had a shorties storm, is that one still raging in v7? Looks like they went ahead and updated the Server Status Page so the Splitter Status Table reflects V7 production. That will make a few people less unhappy. Donald Infernal Optimist / Submariner, retired |

Looks like a BoincTasks History tab. The "missed" doesn't refer to deadline, just that BoincTasks missed picking up the information when BOINC reported the task completion. You'll probably find those tasks in your pendings or validated - you don't show any expired for deadlines. Don't know why BT is missing so many. it always misses a few a day but this is unusual. I haven't had that problem with my first 100 V7 tasks and BT 1.46, so if it continues, take it up with Fred in his forum.

Well I wasn't going to do anything until next week, but I got bored. The GTX 550Ti's on my 2500K are now running V7 and so far so good. If it stays that way then tomorrow or the day after I'll do the same with the GTX 660's on my Q6600. Cheers. |

Have now taken to manually aborting: Richard, Claggy AP: I only run AP on the i7 with the CPU. I don't run AP on the GPUs in this box and I don't run AP on any of the other boxes (CPU or GPU). MB: v7 cuda50 was taking circa 80 minutes to run on the 295s. Far to long, so any cuda50 WUs landing here get aborted. v7 cuda50 wus landing on any of the 580s also get aborted. The ones that have landed here and I have seen seem to have an exponential processing time albiet not as bad as the 295s. I must say that since implementing this practice the number of cuda50 WUs landing on these GPUs is declining to almost being non existent. v7 cuda23 wus landed on the Q6600 with dual GTX580s. These appeared to be going down the same path as the cuda50 so they were aborted. The 295s are now running cuda32 and cuda42 WUs for the GPU. One of the 580s is running only cuda42 WUs at present, the other is running cuda32 and cuda42 WUs at present (just burnt another cuda50 WU there). |

Have now taken to manually aborting: Let the different Cuda version tasks complete, the progress indication on v7 isn't Linear, there is speedup over the second half, let the different Cuda versions tasks complete, then the scheduler will pick the fastest version, at the moment you're prolonging it, Claggy |

Isn't is possible to download stock v7 CPU app and put it in app_info.xml ? Could you, or someone other post the app_info.xml file entries part for stock SAHv7 CPU app?

I was a bit late in noticing that the new v7 has been released. Is the file compatible with AMD CPU's, as it explicitly mentions intelx86 in the name? I guess the following changes would be sufficient for the app_info file <app> <name>setiathome_v7</name> </app> <file_info> <name>setiathome_7.00_windows_intelx86.exe</name> <executable/> </file_info> <file_info> <name>libfftw3f-3-3_upx.dll</name> <executable/> </file_info> <app_version> <app_name>setiathome_v7</app_name> <version_num>700</version_num> <platform>windows_intelx86</platform> <file_ref> <file_name>setiathome_7.00_windows_intelx86.exe</file_name> <main_program/> </file_ref> </app_version> ______________ ![]() ![]() |

Yes, the above mentioned CPU app is for AMD and Intel CPUs. * Best regards! :-) * Philip J. Fry, team seti.international founder. * Optimize your PC for higher RAC. * SETI@home needs your help. * ![]() |

This extra search processing (Autocorrelations) will tend to limit the optimal number of tasks run simultaneously per GPU, to a lower figure, and run somewhat cooler. and of course more work takes longer ;) At least untill the nest round of optimisations & new hardware. :-) Grant Darwin NT |

Claggy Don't think so mate. At the moment things seem to be running wellish. Over the last 2.5 hours I have only received 3 x cuda50 GPU WUs, and 2 x AP WUs on boxes that I don't want AP on. All were aborted. I will say something though that I think you should look at. The limiting of the GPU allocation to 0.02 CPUs or 0.03 CPUs has the effect of nobbling the GPU. The limit should be upwards of 0.10 CPU (I ran my boxes at 0.20 CPU per GPU prior to v7 migration). What this does is to ensure that the GPU gets the resources it needs when it needs them. In observing my systems, I have seen utilisation regularly jump to 0.07 - 0.14. In using 0.20 CPUs, it doesn't mean that it has 0.20 CPUs allocated permanently to the GPU. If the GPU isn't using it, then the processor will. It's just an allocation of resource issue that keeps the GPUs munching as fast as they can. And I have tried this in the past on the Q6600 with 2 x GTX580s and there is a performance improvement. cheers mate |

I did notice that no new tasks are being download for the GPU. Can the v7 application be run on the GPU as well? Or is there another file out there somewhere? ______________ ![]() ![]() |

Was able to contact Eric. I hope the app download crisis has now passed for most of us. I think the kitties have all they need, and are crunching in v7 style on all rigs now. But, I did get a more detailed response from Eric this morning. Unfortunately, I had to rush off to work before I could repost it to you. But, it might still be some interesting information for some. With Eric's permission....... "To be more explicit about what was happening.... We were redirecting accesses to *.exe and *.dll in our download directory from boinc2.ssl.berkeley.edu to boinc2.ssl.berkeley.edu.nyud.net which should provide a cached copy. There are two potential problems with this, some firewalls consider redirecting to be a security risk so they refuse to allow the connection, and some DNS services don't properly resolve nyud.net addresses. Unfortunately when we release a new version, the advantage of still having functional download servers outweighs the disadvantage. I've removed the redirects from georgem, but still have them on on vader." So, there's the nuts and bolts of why Coral Cache was giving some of us fits trying to get our new apps downloaded. Meow, and away! "Time is simply the mechanism that keeps everything from happening all at once." ![]() |

There seems to be a bit of a problem with cuda22 and cuda23 work finishing in errors on other rigs, an example http://setiathome.berkeley.edu/workunit.php?wuid=1256169015, and those pesky GTX 560Ti's are still doing their thing. Also my 1st inconclusive, http://setiathome.berkeley.edu/workunit.php?wuid=1256474447. :-( Cheers. |

Were those rigs producing errors previously? Also my 1st inconclusive, http://setiathome.berkeley.edu/workunit.php?wuid=1256474447. :-( Interesting that one- only difference between the SETI@home v7 v7.00 (cuda42) & SETI@home v7 Anonymous platform (NVIDIA GPU) results is that one was done using an anonymous plaform setup, and the systems had different video cards & different drivers. But both were running the same application, and it configured itself the same way on both systems for processing. EDT- just had a look at my inconclusives- and they're mostly Cuda50s not validating against opencl_ati_sah with a few Cuda42/32 etc types in the mix- but 90%+ are opencl_ati_sah results.

Thanks, The Cuda22/23 examples show as very early 'Too Many Exit(0)s', which tends to indicate Boinc temporary exits for any number of reasons, before the app even starts up. They'll be skunted off to 1 task per day (per app) land :D, looks like the driver is so old that they won't even get Cuda32. As for the problem 560ti, looks like the validator doing its job there. The Ati host there I believe (with limited knowledge on the issue) is running insufficient SDK, might be a more serious situation, though I don't know the details.
