Hi all...I didn't want to hijack Suzuki's thread with my own inquiries.... Any how, I had installed the beta6 Lunatics App on my HP the other day. The first thing I noticed was that my task load was greatly shortened.....And yesterday when I returned home from work...I was very surprised to see that my computer only had the GPU WU loaded and were near completion. I hadn't enough WUs to process during the down time at Berkely... It appears my CPUs had no work. I have uninstalled the Beta6 app for the moment. But my daily task rates are still only 5...one for each processor and the GPU??? Should I just wait for the system to get going again or can I even reinstall BONIC without losing information? Clearly It was me that did something wrong with the Beta6 installation....perhaps something I didn't tick in a box!! |

By all rights your i3 rig would be the only rig you have to really benefit by using Lunatics at this time by using the AVX based CPU app. You also have to remember that if you have a large cache and install Lunatics your estimated run times for a while will be increased decreasing your cache's usual capacity until those run times stabilise again and that looks to be what happened to you (best to do the change to Lunatics after an outage instead of before). ;-) Cheers. |

Thanks Wiggo..... So should I re install the Lunatics app @ Beta6? And if so what boxes should I tick? Really sorry about the dummy questions........My task list is still only showing 5 tasks...the ones that are currently running? Can I reinstall BONIC...or would that make things worse for me? Thanks for your help sir! |

On your i3 the installer will pick the best CPU MB app itself (the AVX app in its case), just make sure that you tick AP processing as well, and if you're going to use the Intel iGPU tick both MB and AP processing there (the AMD/ATi & Nvidia screens should be left alone). I'd just let the Dell run stock as it should wind up getting the v8.05 windows_x86_64 app in the end, just like your i3 and Turion are now doing, and that should be the best app for it. Cheers. |

Thanks Wiggie for your help.... |

Well I did al of the above but only got one task going. Does the app condense all the tasks into just one? So I have uninstalled again.....and now I am getting " No work to process" I think I have upset someone...:-) |

OK. So I am currently processing 4 X WUs and I X Graphics...a total of 5 WU been processed. Each WU is around 3 hours long. While I had the Lunatic installed I had one almost 12 hour WU been processed. Is this in fact what the Optimized app does....? |

On your i3 you need to reserve a core of 2 if you're going to use the iGPU otherwise you'll just suffer cache thrashing which will slow down all core processing, but as I said, it's pointless to run Lunatics on that Dell as it is. ;-) Cheers. |

OK. So I am currently processing 4 X WUs and I X Graphics...a total of 5 WU been processed. Each WU is around 3 hours long. I believe Wiggo mentioned this previously previously. The estimated completion times in BOINC when you change apps will be inaccurate until the server gets an accurate estimate. This requires 11 good tasks to be completed. You can check the status of this from the Application details on your host. So far your i3 has 3 results that count toward this. See Number of tasks completed. SETI@home v8 (anonymous platform, CPU) Number of tasks completed 3 Max tasks per day 36 Number of tasks today 0 Consecutive valid tasks 3 Average processing rate 17.65 GFLOPS Average turnaround time 0.37 days Sometimes you may see the value for Consecutive valid tasks higher than Number of tasks completed. because your returned a good result, but it was perhaps a VLAR or VHAR which falls outside the bounds to be included in Number of tasks completed The Optimized apps work just like the other apps, but have code optimizations which can allow them to complete the same work faster.

On your i3 it is doing, v8 8.00 windows_intelx86 Average processing rate 12.81 GFLOPS v8 8.05 windows_x86_64 Average processing rate 13.53 GFLOPS v8 (anonymous platform, CPU) Average processing rate 17.65 GFLOPS so as you can see you were doing a lot better with the Lunatics app and I still think you'd be better off not using the iGPU and just running all 4 cores instead (as many here have found out through testing). Cheers. |

i GPUs are evil IMO. |

On your i3 it is doing, Again....many thanks...I shall install again and use only 4 CRU... Thank you...:-) |

Here you must follow the old saying, "Patience Grasshopper". Major changes can take up to 4-6 weeks to show their true potential, so just remember the old adage, "Rome wasn't built in a day" (a week or 2 maybe, a month possibly,....). ;-) Cheers. |

Here you must follow the old saying, "Patience Grasshopper". Quite true...... Have re installed and with no IGPU....and will leave it alone now. Thank you again for your information patience...:-) |

Well....things seem to be settling down now...I think my numbers are improving with the Lunatics app.....but cant find the place to check...any how....will continue to leave well enough alone.... Although I have installed Ubuntu and may indeed use it as my new OS on the Dell desk top in a virtual box as it comes mainly in 64 bit...while my Dell is 32 bit...but this might just be as an experiment only trial...:-) |

I think my numbers are improving with the Lunatics app.....but cant find the place to check The quickest method is to look at the run times in the BOINC Manager. The other method is to look at the computer on your Account, click on the Tasks link, and then look at the Validated (or Pending) results & see how long they are running for. One thing I find odd with your i3 numbers is that your Run times are almost 45 min longer than the CPU time- this generally indicates something else is running that is taking time away from crunching the WUs. If you are no longer using the iGPU, once all the existing iGPU WUs have been processed, CPU & Run times should become the same (give or take a few minutes). If they don't, i'd suggest running Process Explorer to see just what is interfering with your processing. Your Core 2 Duo times are almost double, so something is going on there as well, impacting on your crunching. Grant Darwin NT |

I think my numbers are improving with the Lunatics app.....but cant find the place to check Thanks for that...I had put that down to the fact that I have recently installed the Lunatics app....and that it takes soem time for it to settle dow. For example the estimated run time have already dropped significantly to date... But again I shall consider to monitor... I appreciate your help....thanks.... |

Yeah!! Just checked now and the computers with Lunatics running are throwing up the anomalies between run time..and processing times... I shall let it settle for a while.... |

Nice thing about doing it in cc_config is that it can be done on the fly, with changes being immediate and not requiring a shutdown/restart, unlike app_config changes. With low power GPUs, the only advantage of running 2 at a time is that the 15-20sec startup time where the GPU isn't crunching yet is offset by the other WU that is being processed. Overall, the GPU output is about the same as 1 at a time, except you loose the output from that second CPU core that's required. So the end result is (slightly) less WUs per hour. The big advantage of 1 at t time is that you never get a mix of WUs on the 1 GPU- ie 1 GBT and 1 Arecibo. When that happens, the Arecibo crunching time can be as much as triple it's usual run time. Grant, thinking this might be a better place for our discussion instead of the Win 10 thread :) |
