Post: Hosting I can do, tweaking, not a chance. Not a "tweaking", just a small correction will be needed from time to time (at a time of SETI@home "tasks" webpage changes - for example, recent SETI staff's change was the addition of "Run time" column between the "Status" and "CPU time" columns and I changed the script accordingly)... If You will have no time to: 1) examine the "Tasks" SETI webpage changes and 2) change the main script file "pc_functions_inc.php" accordingly to reflect such changes, then I can look at webpages and suggest a small changes to the script (or even I can suggest new version of the whole file - probably it will be easier to upload the new whole file than to edit the hosted script file and upload?). I did it before and I'm hoping to find differences easily again. It's harder to say than to do it ;) Of course, my such finding and interpreting work doesn't matter without Your help to hosting providing and uploading new files to Your site. I (and I hopes, not only I'm) would appreciate Your hosting/uploading efforts. P.S. I don't like to insert huge changes into working program created by another person, so I can guarantee what my changes will be minimal, such as an additional one or two lines of code or even change of several characters into one line. P.P.S. And, of course, excuse me for my bad English please - I had no live experience on it, just Windows messages, games and several movies... _____________ WBW, Leopoldo |

(another) dumb CUDA question
(Message 933794)
Posted 16 Sep 2009 by Leopoldo
Post: I have Hyperthreading enabled and "use 4 cpu's" set on the pref's page ... will I have 2 or 3 SETI's running?? Version 6.6.36 will use website setting 6.1+ "On multiprocessors, use at most" - "100 % of the processors", not the "5.10 and earlier" setting, so you will have on your P4 with hyperthreading and 8400GS 3 tasks running - 2 CPU (multibeam workunits marked as version 6.03 or astropulse workunits) + 1 GPU (multibeam version 6.08). You can check this in the windows task manager: 2 tasks "AK_v8b_win_SSSE3x.exe", each using about of 47% processor and one task "MB_6.08_CUDA_V12_noKill_FPLim2048.exe" nearly of 5%. Edit: the next CUDA problem requires your attention - the VLAR-processing, when the whole windows system becomes too inresponsive - even simple windows redraws very slowly... Now you are using MB_6.08_CUDA_V12_VLARKill_FPLim2048.exe which will kill every VLAR workunit assigned to it (look at executable name ;) ) - this behavior is good for system of fire-and-forget type (no babysitting required). If you wish to lost no any received workunit (and thus your system will no receive WU limit penalty) - then check threads about resheduling/rebranding at this Number crunching forum or at Lunatics corresponding thread. ___________ WBW, Leonid |

Post: 9/16/2009 9:37:18 AM SETI@home Message from server: No work available for the applications you have selected. Please check your settings on the web site. Hello, Edward! SET@home project have its own preferences at address http://setiathome.berkeley.edu/prefs.php?subset=project Did you set "Use Graphics Processing Unit (GPU) if available" to "yes" before the Unified Installer? After Unified Installer completed its work you launched BOINC. BOINC asked for work from server and received no CUDA-marked workunits (version 6.08) You saw this situation and relaunched BOINC - and, BOINC itself (as having no CUDA-workunits) silently deleted mentioned in app_info files MB_6.08_CUDA_V12_VLARKill_FPLim2048.exe, cudart.dll, cufft.dll and libfftw3f-3-1-1a_upx.dll from project folder. It's old BOINC behaviour, I saw it before... And, because of this files doesn't exists at BOINC servers (Unified Installer is from Lunatics site, you remember?), the attempts of downloading them fails. Moreover, missing files leads to errors like your: <core_client_version>6.6.36</core_client_version> What can you do?

Post: I've been getting s display driver has stopped responding and recovered message. Is their any way to fix this problem? User solutions: www.nvlddmkm.com Detailed description from MS: http://support.microsoft.com/kb/940105/en-us I'm using the 32-bit patch from above MS-link (my 32-bit Vista have no SP1) and the setting "Performance" user mode in 3D section (with preview) of the nVidia Control Panel. Never saw "stopped responding and recovered" since that time. |

Post: After app init: total GPU memory 536543232 free GPU memory 205757696 It seems like your videocard has too little free videomemory for CUDA-processing... Did you try a reboot and saw the next completed result after the reboot? You should find what is eating your videomemory... For example, my Vista eats much less videomemory: Total GPU memory 805306368 free GPU memory 691068928 |

Post: Any news yet on a new multiplier for MB6.08 with CUDA 2.3. I believe there was a remark in a thread a few days ago about this (Richard?). I did miss this thread but after looking into completion time I'm using multiplier factor of 14/9 now to increase my old value (nearly 9 minutes with version 2.3 versus 14 min at 2.2 - 8800 Ultra) DCF now is 1.10 I'll look further... |

Post: ... For me much simplier is to see into workunit header for the <chirp_resolution> (new has 0.1665, old had 0.333) but I think the original question was answered and we understood each other clearly ;) Good luck! P.S. And excuse me please for my bad English - I'm only a computer technician and I studied English only from the point of view of computer phrases :( I have no live experience in this area... ___________ WBW, Leonid |

Post: How fast is everyone completing these tasks in? With CUDA 2.3 new MB workunits (chirp 0.17) are calculated at 19 minutes, while old (chirp 0.33) did at 9.5 min. (with CUDA 2.2 old MB workunits did at 14 min) NVIDIA GPU 0: GeForce 8800 Ultra (driver version 19038, compute capability 1.0, 768MB, est. 69GFLOPS) No overclocking. |

Post: Is the cudart.dll in the program files\boinc folder not used ? Excuse me, but I don't know this exactly (I have an my own opinion - cudart.dll from Program Files folder is used for GPU speed calculation, because text line like "NVIDIA GPU 0: GeForce 8800 Ultra (driver version 19038, compute capability 1.0, 768MB, est. 69GFLOPS)" posts before the start of any project) I had never change anything in Program Files\BOINC, only in project folder (because only specified at app_info.xml files from project folder copied into corresponding slot and executes by the BOINC Manager)... |

Post: Everybody seems to be happy here but I still cannot upload my results from PCs at work. I took the results on my USB key home and it uploded immediately. Simple check... What can You see if You do typing http://setiboincdata.ssl.berkeley.edu/sah_cgi/file_upload_handler as URL address into your browser? I see: <data_server_reply>

Post: First of all I would like to say - these libraries are useful for Raistmer's optimized CUDA-application (For example, I'm using MB_6.08_mod_CUDA_V11_VLARKill_refined.exe) Unoptimized (stock) CUDA-application uses an old versions of this nVidia libraries... @Fred J. Verster: IMHO, these libraries can't work with unoptimized application - so app hangs How do I get the ' old' cudart & cufft.dll's back? Libraries for unoptimized (stock) CUDA-application can be downloaded from http://boinc2.ssl.berkeley.edu/sah/download_fanout/cudart.dll and http://boinc2.ssl.berkeley.edu/sah/download_fanout/cufft.dll Old libraries for optimized application must be extracted from the old archive with this opti app. What do I do with them? @SmartWombat: If you are using optimized CUDA-application then just unarchive libraries and copy into SETI@home project folder (For example, in Vista default path is C:\ProgramData\BOINC\projects\setiathome.berkeley.edu) |

Post: For all CUDA crunchers. Many thanks, Raistmer! 8800 Ultra - common workunit falls from 14 min to 9 min ;) To keep DCF at 1.0, "flops" had been changed accordingly :) ___________ WBW, Leonid |

Post: These were not the normal "Cannot connect to server, check your internet connection" messages. Boinc Manager was losing contact with boinc.exe. The message was "Cannot connect to CLIENT". Yes, I had the same connection error. Earlier I published my lines of stdoutdae.txt (about upload problem) and the lines of stderrdae.txt (the error description). You can check Your files after killing the boinc.exe... "nbytes" algorith has been changed in 6.6.38, here is the quote from change log: - client: changed file upload logic At present time I'm using the .37 (with old upload logic) version again... |

(Message 919843)
Posted 20 Jul 2009 by Leopoldo
Post: Hi! I thought that it might be their side... No, BOINC uses reply from website "www.google.com" as indicator of internet availability (AFAIK), but I mentioned inavailability of this address several times (at that times country-specific address "www.google.ru" works pretty well as usual - so I think problem exists at DNS of google, not BOINC). BTW, according to http://boinc.berkeley.edu/wiki/Client_configuration You can set BOINC to check internet access with another address (for example, Your ISP website) - with tag "<network_test_url>URL</network_test_url>" in "options" section of cc_config.xml |
