GPU app - beta version for linux nvidia

Posted 1 Apr 2019 by mmonnin Post: I see credit was recently doubled to 8,000 (and the average runtime also seems to have increased with it, though not quite doubled) and now decreased to 800. I'm not complaining, just curious about the reasoning. One of the lowest credit projects now for GPUs. 261k for a 1080Ti yesterday but not sure if that was all at 800 or some older 4k/8k tasks. SETI uses CreditNew and will be better than 1 credit/sec so like 100k or something. Asteroids is probably lower but A@H is more of a CPU project IMO. Collatz, MW, E@H, GPUGrid, Enigma, Amicable, PrimeGrid, and Moo produce more. If the GPU app can do 20x more work then per second it should receive 20x the credit compared to your own CPU app. |

Posted 29 Mar 2019 by mmonnin Post: I got a little sneaky solution for me. That's the BOINC client saying job cache is full so it won't contact any project server for more work. |

Posted 26 Mar 2019 by mmonnin Post: It was paying around 20 per run sec on my GTX 1080 which is better than many GPU apps but not crazy. Now it's only paying 0.08 per run sec, 1/250 of what it was which is crazy low. It's worse paying than Asteroids on a GPU. Einstein pays 5-7 per run sec. Tasks vary in length so fixed credit is unfair as well. The only other way is if the FLOPs calculated during the task was known for each task. The prior method was open to abuse since it was a function of the GPUs FLOPs and time. |

Posted 26 Mar 2019 by mmonnin Post: lol, at least you guys are getting tasks. I just keep getting "got 0 new tasks". It seems like the 760 should be able to receive tasks. The app is Linux only so the 210 won't work. And it's to old. |

Posted 25 Mar 2019 by mmonnin Post: Only errors here. 2nd person for a 6xx card to not work with 418. The card might just be too old. |

Posted 25 Mar 2019 by mmonnin Post: Yesterday was triple the output of the Formula BOINC Sprint's best day. I can only see credit, not # of results, so that's what I mean by output. CreditNew provides lower credit for CPUs than the current system here so those CPU credits will be lowered too. But something will have to be done. |

Posted 25 Mar 2019 by mmonnin Post: ok, see no quick way to install cuda 10.1 , version 9.1 is latest on Ubuntu 18.10. Driver 418 is available if you add the nvidia repository. |

Posted 24 Mar 2019 by mmonnin Post: There is only once per day external update to FreeDC/BOINCSats but FB can read the team points every hour which worked for the Sprint. Marathon may just look once per day. |

Posted 24 Mar 2019 by mmonnin Post: Just low to mid 70% GPU util so I'm running 2x. Now mid 90%. Hotter is to be expected. My Ti is in a dedicated system so slow browsing won't bother me. I'd consider it low, so I added another task even at the expense of another lost CPU thread feeding the GPU exe. Some other projects have options the user can configure, I'm guessing something like the blocks and threads per block that you mentioned. Collatz, Amicable and even SETI's user apps can have custom settings that can push GPUs harder. Amicable has a kernel size setting on BOINC's user preferences. Collatz and SETI can look at text files in the project folder. Memory usage in Nvidia X server is showing about 1.5GB with 2 tasks so plenty of resources left. 567mb per task. 0-1% PCI-E usage. Just 115-118 watts via nvidia-smi on a 1080Ti. Same OC uses 185-195 watts with E@H. |

Posted 23 Mar 2019 by mmonnin Post: First, YEAH!!!!! A new GPU project! Cool and thanks!!!! I recall hearing that somewhere as well and a reason I installed just 396 on my 1080Ti. Pls report back if it's still the case. Attempting to install 418 broke my Ubuntu install and I don't recall the exact OC clocks on the Ti but it's performing just as well on E@H with 418 vs 396 after the Ubuntu reinstall. The E@H frequency is constantly changing which changes the compute time slightly so if there is a driver difference it seems small with OpenCL. Comparing the 11 tasks I received here at NF and with a random Ti at Collatz, the RAC is about 1/3 at Collatz which is known to be a very high RAC project. Once people realize the RAC possibilities here, expect more members to flock here. Especially with the limited # of GPU projects. |

Posted 23 Mar 2019 by mmonnin Post: GTX 1060, only a couple of months old, running proprietary driver 390.116, the latest in the repositories. Thanks for your "insight". You need at least 418, which are in the nvidia PPA. sudo add-apt-repository ppa:graphics-drivers/ppa update and it will be available in drivers. |

Posted 18 Mar 2019 by mmonnin Post: I have some information regarding server load. I think a good measure of that is how many WUs are processed per hour. Here is an average, broken down by day: https://stats3.free-dc.org/stats.php?page=proj&proj=num This shows over 20x normal load by credit at the peak and 9-10x the last two days. If your GPU version is 20x as fast on just a 1050 I would expect there to be much more 20x once a GPU version is released. More people will come to the project with GPUs to cash in on the higher credit. Assuming the same task is worth equal if ran on a GPU vs CPU. |

Posted 14 Mar 2019 by mmonnin Post: I saw ~380k tasks available a little after the event start and now its over 400k. I don't think FB has as high of participation than the Pentathlon even if there are more teams. Some projects were in their 1st year of being a BOINC project last calendar year and did not know about being listed for FB Sprint. Some tripled their normal daily output and their servers suffered. |
