New ones currently in test on beta. Though I regularly post new packs for anonymous platform here: http://setiathome.berkeley.edu/forum_thread.php?id=79765 that allows preliminary testing on main too. SETI apps news We're not gonna fight them. We're gonna transcend them. |

Correction: as was said all GPU apps are "Lunatics" one so second option would be to actively participate in testing. That is, to try different options (not just run with defaults) and even to conduct some offline benchmarking if required. SETI apps news We're not gonna fight them. We're gonna transcend them. |

All three of my current PCs are NV based. Each of the PCs has a pair of GPU, one with GTX780, one with GTX960 and one with GTX980s For such http://setiathome.berkeley.edu/result.php?resultid=5021927438 type of errors it's coincidence.

Raistmer, . . FWIIW I am seeing similar results. I have gone back to r3430 on the rig with the 970s for that reason and have had a few of those errors too. |

Thanks you Raistmer & Zalster for your clarifications to my previous post. As for: Did you check AR values for tasks in comparison? Different AR means different set of searches used so different performance and behavior. I've never done that before...but I saw it mentionned in a few threads. I was just pointing out something visible in BoincTasks that was not visible with the Boinc Manager since it relates to SoG and I had read it uses a full core when running with commandline. In case, my copy/paste of the text above with the CPU% wasn't clear (since I forgot to include the column headings), here's an image: Is it worth looking at the AR values? If so, is there an easier way to do so other than having to multi-click your way to each individual report? |

It depends. Generally AR-dependence is known thing.

suspend network communications, accumulate results, parse client_state.xml via script: http://lunatics.kwsn.info/index.php?action=downloads;sa=view;down=497I have a few tasks with the status "Uploading (suspended - user request) ..." for both the GPU & CPU. I placed the 3 extracted files from the downloaded compressed file into the folder: C:\ProgramData\BOINC from the DOS cmd line, I tried: perl print_elapsed_times_V6.4_MB.pl client_state.xmlwith and w/o client_state.xml ...but without success; the content of elapsed_times.txt only has the headers: App Name Task name AR CPU time Elapsed pref_wg_size pref_wg_num_per_cu hp use_sleep sbsWhat am I missing? |

rename client_state.xml into 1 or change corresponding line inside script. SETI apps news We're not gonna fight them. We're gonna transcend them. |

rename client_state.xml into 1 I've tried different options and this is the only one that provides any output: in: print_elapsed_times_V6.4_MB.pl , I changed the 1st line to: $path="C:\ProgramData\BOINC\"; In DOS window (cmd.exe), I typed: C:\ProgramData\BOINC>perl print_elapsed_times_V6.4_MB.pl client_state.xml...and I got 3 screens of output (see first few lines below) and nothing new in: elapsed_times.txt C:\ProgramData\BOINC>perl print_elapsed_times_V6.4_MB.pl client_state.xml Bareword found where operator expected at print_elapsed_times_V6.4_MB.pl line 2, near "$results="elapsed_times" (Might be a runaway multi-line "" string starting on line 1) (Missing operator before elapsed_times?) String found where operator expected at print_elapsed_times_V6.4_MB.pl line 4, near "open (RES, "" (Might be a runaway multi-line "" string starting on line 2) (Missing semicolon on previous line?) Bareword found where operator expected at print_elapsed_times_V6.4_MB.pl line 13, near "$ar="N" (Might be a runaway multi-line "" string starting on line 4) (Missing operator before N?) String found where operator expected at print_elapsed_times_V6.4_MB.pl line 14, near "$elapsed_time="" (Might be a runaway multi-line "" string starting on line 13) (Missing semicolon on previous line?) Fyi, I haven't played with Perl in over 15 years and I was hoping I wouldn't have to! ;-p |

Once more: rename client_state.xml to 1 put all in same directory. Run script. $path="1"; <=== input file name SETI apps news We're not gonna fight them. We're gonna transcend them. |

Once more: rename client_state.xml to 1 "Once more:" I had tried that as is implied by: "I've tried different options... I thought maybe, it was because I hadn't deleted: elapsed_times.txt so I ran it again: C:\ProgramData\BOINC>perl print_elapsed_times_V6.4_MB.plbut there is still only a line of headings in: elapsed_times.txt Please be more detailed in what needs to be done as there is obviously something else missing (other than: rename client_state.xml to 1) that someone without working knowledge of Perl needs to make it work. Cheers, Rob :-/ |

I tried to reproduce your outcome and found that pointed to wrong tool: Description: Perl script that allows to extract timings along with app names, task names and app's launch parameters from KWSN benchmark log. It's extraction from KWSN log not from client_state.xml. Sorry, I gave misleading instructions this time. Correct script is extract_times.pl but seems it's: 1) not uploaded to download section 2) not updated to SETI8. I'll do required updates then post the right link. Sorry for inconvenience.

I'll do required updates then post the right link. Sorry for inconvenience No problem...I was more worried the little knowledge there remained from my major in Comp.Sci. (done in the 90s) had been a total waste! lol In the meantime, I'm now using your latest NV_SoG (MB8_win_x86_SSE3_OpenCL_NV_SoG_r3484.exe) on a Xeon W3550 with a GTX 750 Ti. I was OCing it a bit (~1300MHz; base is 1162MHz) and after 3 non-vlars with no issues, the GPU went down to 400 MHz and was stuck there. I ended up rebooting as I didn't know what else to do. Other than that, let me know if there's something you'd like me to concentrate on (such as: guppi) either in the regular project or S@H Beta. If there isn't anything specific for the GTX 750 Ti, I might be able to get a hold of a: Nvidia evga gtx 550 ti Otherwise, let me know what nvidia cards you'd like tested (if any) and I'll look to see if I can find a cheap one around my hood. Cheers, Rob :-) |

Are these two running VLARs with acceptable GUI lags at default config, single task per GPU? SETI apps news We're not gonna fight them. We're gonna transcend them. |

Are these two running VLARs with acceptable GUI lags at default config, single task per GPU? Currently running non-vlars on GPU as I was having fun maximizing throughput by sending tasks from CPU to GPU and vice-versa. I can send any of the 94 vlars (~40 blc, and ~55 2010s) from the CPU queue to the GPU. If you'd like them to be of a specific kind of vlars, I can do so since my little batch program transfers those that I have Suspended. Also, in the future, if you want me to run small batches with similar file names, that's easily doable. Just to give you an idea, I've got the following in the queue: Tasks File names 11 01au10af.25634.47161.11.38.###.vlar 22 02jn10ab.6266.1294.10.37.###.vlar 5 blc3_2bit_guppi_57451_70772_HIP117779_0027.22322.831.17.26.###.vlar I'm hitting the pillow soon so I'll transfer some blc...vlars to the GPU in the morning if you don't have a more specific request. Cheers, Rob :-D |

Both. Actually - all ARs range. But usually very VLARs cause troubles with usability. SETI apps news We're not gonna fight them. We're gonna transcend them. |

I added my laptop to beta for the iGPU only. I noticed it restarts a lot on guppi but not on arecibo. If the CPU is doing nothing on that laptop, it **might** be good to have it "Use at most @ 99% of CPUs" (Options | Computing Preferences... | Computing). The way I see it (and I might be wrong), the GPU-processed tasks need to be validated. If everyone on Beta only used the GPU apps then the validation process might be reporting False-Positives since: if there is a bug in the GPU apps that is not in the CPU apps, then it would not report as many "inconclusive validation". Does anyone have a different thought on this? (...as I'm always interested in learning about the process behind the scene...and I'm putting together a few pieces of info collected here-&-there that might not be what the full picture is like). Cheers, Rob :-} [edit] I noticed on a few old laptops (w/o GPU) currently on S@H Beta that the CPU apps are: v8.04 (Windows) & v8.05 (linux) but I don't know if there is any documentation about they do differently as compared to v8.00 on S@H stock, and how different they are from the GPU apps. |
