If the V7 GPU app's are doing more Intensive work on the Wu's , is it maybe more needed to free up 1 core on cpu , to be more effective for GPU work ? Cuda apps under V7 'shouldn't' be using more CPU. Juan tested this earlier & reported no difference with or without freeing CPU cores, with multiple tasks per GPU. The extra intensive work is taxing on the GPU memory system. 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 ;) No idea where Credits will settle.

Isn't is possible to download stock v7 CPU app and put it in app_info.xml ? Thanks works fine it seems. DL with Chrome with no probs. |

Just a remainder i only have INTEL CPUs and Fermis/Kepplers GPUs. And in all the test i mantain only 2 WU crunching (1 or 2 Vlars at the same time on each GPU)at a time to avoid video lag. |

Isn't is possible to download stock v7 CPU app and put it in app_info.xml ? In response to an enquiry by PM: the stock CPU app, as usual, can display eye candy or a screensaver. For that, you need http://boinc2.ssl.berkeley.edu/sah/download_fanout/setigraphics_7.00_windows_intelx86.exe |

As most of my machines have 7 or 8 day caches with 100 tasks, & are downloading resends, I don't expect to run out of work before the next lunatics release. Perhaps some of my faster machines will run out & flip over to PrimeGrid for a bit, but that is OK with me. Keeps the details page on my machines from getting junked up with stock app info.

Well, my first v7 has started. Estimated 15h 15m. We'll see. I went and edited my app_info.xml, included the new app by hand. 30-May-2013 22:12:30 [SETI@home] Starting task 27no10ad.29489.21917.6.12.77_1 using setiathome_v7 version 700 in slot 0 |

I just noticed something that I don't remember seeing on the V6 WU's for GPU. On PC ( #1 ) 5953062 the GPU wu is showing " Running ( 0.0236 CPU's + 1 NVidia GPU )" CUDA 32 WU On PC ( #2 ) 6994641 the GPU wu is showing " Running ( 0.00579 CPU's + 1 NVidia GPU )" CUDA 42 WU The difference in CPU usage... Can this be because of the different Video cards ? #1 has the GTX 460SE and #2 has the GT 430 . OR because of the different Cuda apps being used at this time ? |

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 |
