Posted 14 Dec 2013 by ausymark Post: hi Mikey Thanks for that info which i did before making my initial post, however since the issue is with beta software i wouldnt mind testing it out so that we can help improve it so future versions dont have this issue. |

Posted 14 Dec 2013 by ausymark Post: Hi Jake I just came across this thread. Please see my thread here about an issue I am having with the current 1.28 OpenCL-nVidia app: http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3421&postid=60577#60577 Cheers Mark |

Posted 14 Dec 2013 by ausymark Post: Hi Len The frequency setting does nothing with my set-up, I've had it up to 10,000 instead of 60 (updated the project etc) but it had little to no noticeable affect. I will look into the command line options once I find where they are listed. The silly thing is i can run the non-modified fit application without lag, so the real question is whats the main difference, processing wise, between the standard and the modified app? That may help work out what may need altering, otherwise im going to playing hit and miss with the options. Addition: Just noticed that the modified fit program is an OpenCL - nVidia application that is currently in beta, that maybe the issue there. Cheers Mark |

Posted 14 Dec 2013 by ausymark Post: Hi Link Im not talking about out of the box BOINC (mines been set to crunch while using the PC for years now), I am talking about what is essentially meant to be a low priority background task that causes lag. Ive narrowed it down to I think just one Milkyway program, the trick now will be to find why its causing lag when its "sister program" is not (see my other post) Cheers Mark |

Posted 14 Dec 2013 by ausymark Post: Further Update It seems to be (so far that I have noticed anyway) only on "Separation (Modified Fit) programs/work units. The standard Separation program/work units go through fine without causing any lag. So I guess the questions should be asked - what is the Modified Fit version doing that the standard Separation isnt doing that could cause a nVidia GTX580 to lag? BTW I am running Ubuntu linux - so any Windows related issues wont be applicable. Cheers Mark |

Posted 13 Dec 2013 by ausymark Post: yea, ive tried that, even with figures all the way up to 2000 instead of 60 with no real difference. I may have to try the config file option and play with the settings. Its just annoying that both Seti and Einstein work out of the box without the need to go to the config file route unless one wants to further tinker - not to fix up an issue for something that should be a non-obtrusive background task. Anyway, its tinkering time :) |

Posted 11 Dec 2013 by ausymark Post: Hi Donald For a start I would not use the version of BOINC that comes in your repository as they can be significantly out of date. (I am using Ubuntu Linux 13.10 here.). The current versions of BOINC are 7.xx series. The best way to do it is to create a boinc directroy in your HOME directory. Download/install boinc using the latest boinc and install instructions from the boinc site. Then add your project(s) as per normal. You will then get the latest apps to get around the issue you are having, potentually incluting optimised apps to further improve your results. Hope this helps |

Posted 10 Dec 2013 by ausymark Post: Hi Team, I am running SETI and Einstein @ home on the GPU with no log issues, I am hitting lag (slow desktop interface response) with the following: Intel i7 2600K CPU Overclocked to 4.5Ghz, nVidia 580 GTX GPU, 16GB RAM Boinc version 7.2.33 OS: Ubuntu 12.10 Linux 64bit With project specs as: Resource share Determines the proportion of your computer's resources allocated to this project. Example: if you participate in two BOINC projects with resource shares of 100 and 200, the first will get 1/3 of your resources and the second will get 2/3. 50 Use CPU Enforced by version 6.10+ no Use ATI GPU Enforced by version 6.10+ no Use NVIDIA GPU Enforced by version 6.10+ yes Is it OK for MilkyWay@Home and your team (if any) to email you?

Higher numbers may run slower but will provide a more responsive system. Lower may be faster but more laggy. default 60 (corresponds to 60 fps) 10000 Period (in milliseconds) to check for scene updates 30 Change how fast the view randomly moves around 5 Make particles bigger or smaller 250 Make particles bigger or smaller when using uglier particles 40 Lag occurs when running Separiation (Modified Fit) 1.28 (opencl_nvidia). (It may be lagging for other milkyway apps as well, this is just the one running atm causing lag). I have also tried it with running CPU apps with no apparent difference. Any ideas would be appreciated. |
