Script recognizes only older version of CUDA. zi missed there. I'll add new CUDA build recognition in next version. SETI apps news We're not gonna fight them. We're gonna transcend them. |

What would the perfect report look like for you? Actually this script for your convenience cause you asked for tool to look into AR field en masse. Testing type I currently need I usually post here or in beta news thread. There will be new build soon that requires testing. SETI apps news We're not gonna fight them. We're gonna transcend them. |

send them to me. P.S. Ah, and before doing that make sure missed tasks not overflowed ones. Script recognize and excludes overflows automatically. Cause they have distorted timings. SETI apps news We're not gonna fight them. We're gonna transcend them. |

I never run script in BOINC's own dir. Copy xml file into another dir and run there.I shut down the client and made a copy of client_status.xml, 5 tasks were in status "uploading" and only 3 showed up in Times.txt For both of the missing, they are in client_state.xml and can see the AR value (ie: ar=0.427524) in the stderr. P.S. Ah, and before doing that make sure missed tasks not overflowed ones. Script recognize and excludes overflows automatically. Cause they have distorted timings.If by overflows, you mean: SETI@Home Informational message -9 result_overflowboth of the missing in Times.txt have it in their stderr. So it seems (to me) that it works as intended...except for cuda50 tasks are missing (on my 2nd rig that I am using to compare results to your latest NV_SoG revision). |

Please test this build: https://cloud.mail.ru/public/9ifo/XQTdqmfJJWow, that's a big improvement in completion time for non-VLARs as compared to r3484 on GTX 750 Ti! NV_SoG_r3484: 15-16 mins NV_SoG_r3486: 12.5mins with no commandline for either It's even the 1st time that it's better than cuda50 (3tasks=~39mins) Keep up the great work! |

Please test this build: https://cloud.mail.ru/public/9ifo/XQTdqmfJJ http://setiathome.berkeley.edu/result.php?resultid=5042270028 Here's one that was crunched with this version. Stderr misses the normal output of used parameters but includes a lot of other other information. The CPU use don't seem to be any different to the previous r3486 version. The parameters used were: -sbs 384 -use_sleep -hp -instances_per_device 1 -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 32 -oclfft_tune_cw 32 It was run on my GTX970. In general all these SoG applications are very sensitive to the CPU load. If it reaches 100% the driver reset is bound to happen although I have now the TdrDelay set at 8 seconds. So I have reserved 1.6 CPU cores per MB task because this is also my daily driver so extra head room is required. I will set up now the non-Boinc use limit to 18% to ease the effect of other running applications. |

send them to me.Here are the files for a situation where I have 8GPU and 2 CPU tasks being blocked from Uploading. Only 1 CPU file is in Times.txt and there is no Overflow in client_state.xml https://www.dropbox.com/sh/5jbnvivo9mtcq5g/AADIpSRrHx_rnPzaDyecZEqsa?dl=0 I'm tired but I double-checked so I don't know if I forgot something. Cheers, Rob zzzz soon |

Commandlines are the same, no -tt 90 nor -use_sleep r.3486 Final WU true angle range is : 0.008880 http://setiathome.berkeley.edu/result.php?resultid=5046873396 Run time 18 min 25 sec CPU time 16 min 46 sec WU true angle range is : 0.009471 http://setiathome.berkeley.edu/result.php?resultid=5046872611 Run time 21 min 1 sec CPU time 20 min 48 sec r3430 WU true angle range is : 0.008136 http://setiathome.berkeley.edu/result.php?resultid=5044042638 Run time 20 min 29 sec CPU time 18 min 29 sec WU true angle range is : 0.008136 http://setiathome.berkeley.edu/result.php?resultid=5044042824 Run time 20 min 58 sec CPU time 17 min 56 sec There is some variance as they speed up when teamed up with non guppi. From what I can see they are comparable. Non-guppi times are exactly the same in both versions. None of the r3486final non guppi have yet validated. If you want those, we will need to wait for my wingmen. |

Another test to do by volunteers: On beta (or in anonymous platform mode on main) take 8.16 OpenCL app or later and add -tt F parameter to command line. increase F value (default is 15 that means 15 ms target time for partial PulseFind kernel) and watch for host usability (that is, GUI lags, missing letters at typing and so on). At what F value lags appear? From performance point of view it's better to have longer kernels but this can result in GUI lags. This testing needed to establish best possible default value for unattended run. EDIT: describe your host config (preferably with link to host on beta) along with report, please.

Thanks for such good structured and detailed report. Nothing else with this build. I'll post another one soon - would be very good if you could do just similar run with it too. SETI apps news We're not gonna fight them. We're gonna transcend them. |
