Post: Well new WUs would be nice for starters but "don't expect AstroPulse tasks will be available every day (they are 30x less 'in stock' than "SETI@home Enhanced" tasks)" Oh, BTW ...WHY? Anyway, I just want a few WUs to test that this release works better than the Lunat... app (read virtually nil GPU processing & virtually 100% flat-out CPU processing irrespective of standard BOINC non-geek CPU usage settings, abandoned some time past). Now waiting for flak from Raist... |

HELP upgrade in old PC.

Post: a core 2 duo on a board with AGP. The ASROCK 775i65G (don't ever use the ...GV 'board as it won't run Conroe) is a gem. There are probably others. The 775i65G runs quad-core CPU's too. I have one fitted with a Q6600. It requires CL2 memory which will enable 1066mhz:- the board automatically overclocks the RAM so it takes about 10 seconds longer during POST. |

Optimised app for ATI/AMD 3850 GPU processing.

Posted 23 Nov 2011 by Ray_GTI-R
Post: Thanks for the reply(s). I can now process Seti AstroPulse 505 v5.05 on the HD3850 thanks to persistence / Lunatics - however after some time, checking efficacy, I chose not to continue on this PC since duration vs CPU-cram+heatup+unavailability vs credit-awarded-that-is-obtuse - read ... "proven & unacceptable" compared with other, more modern GPU-happy, non SETI projects. The HD3850 is now happily processing results from those other projects giving well proven, realistic-duration (vs CPU-cram+heatup+unavailability vs realistic credit), cool-running* GPU tasks. In fact I have two very cool-runing* AGP cards. One HD3850 is quite old but very clean (hint ... dust filters! On ALL PC's). The other HD3850 is brand new. Both HD3850's are processing with no CPU/GPU dramas. I also have a recently-acquired newish used, tested good spare HD3850 which I may fit into the wife's P4i65GV / Northwood 2.8 HT etc shopping trolly:- good for 10K-a-day guaranteed work result ... running non-SETI tasks - sadly :-) Ray * via standard clock speeds/GPU/CPU/case cooling/PSU requirements etc. PS:- Let's face it who needs opinion ... other comments are extraneous & duly ignored. PS2:- another example. Seti AstroPulse 505 v5.05, 1 task running 24/7 on a headless server, an Atom 330 ... 2-core (HT 4-core) ... & HD2400 PCI (RV610 - FP32 ... not PCI-e / not PCIanything else) worked thanks to persistence / Lunatics. But it took about 5 DAYS to complete a Seti AstroPulse 505 v5.05 task because of the inexplicable reliance on ugg Atom CPU _instead_of_the_very-capable_GPU |

Post: I bought the HD3850 (512mb) because it has double precision that SETI requires for standard GPU tasks. That was my only reason for spending a LOT of money (and >4weeks' wait) on this card. Because that's the error message I got from SETI. When I fitted a DP card the error message went away - DUH See also:- http://www.unitedboinc.com/en/boinc-info/56-info/185-computation-credit Specifically ... SETI@home uses almost all single-precision floating point math. Translated ... if ONE math requires double precision then a single precision GPU won't EVER work! Running Astropulse on a 3850 [DP] card works - very badly - see elsewhere. Facts only. From my perspective. Opinion (rare for me):- Clearly, with the passage of time documentation/software becomes outdated and if so it is the responsibility of the genius developer/author to post relevant updates wherever confusion occurs to us simpletons. |

Gripes and Kudos II
(Message 1169576)
Posted 9 Nov 2011 by Ray_GTI-R
Post: Gripe:- after upgrading to a double-precision GPU (hard to find & expensive on an AGP slot) this PC recently completed one AstroPulse task running continuously that took +/- 23 hours, credit = 730. The GPU was used for only 2-3 seconds every minute, so it's vastly under-used. BUT - the GPU is blocked from running any other GPU task from any other project for the entire time the AP task runs. The same PC running CPU & GPU mixed projects continuously, produced 11,688 credits in roughly the same time, with the GPU running 96/7% all the time. That's why I took the trouble & expense of buying the graphics card. I've taken Astropulse off my list of projects until tasks utilise a workable GPU to the maximum :-( |

Post: "what you upload can be bigger and I've often done that to get a better avatar pic" Interesting. Thanks for that. I've adjusted the avatar to a better (!you decide!) image, sucessfully, by again following the link that arkayn provided. Still would like to know how to use the same (ugly) avatar on all BOINC message boards/forums. Anyone? Thanks, Ray |

Post: Yeah. I know. I have tried really hard (again) with no joy. I notice that your avatar properies are "http://setiathome.berkeley.edu/user_profile/images/8179000_avatar.jpg" How do I get my avatar in my user_profile/images/ folder? I have tried http://setiathome.berkeley.edu/create_profile.php and there is a "profile picture shown to the left". But no joy, again. Honest - my avatar is a .jpg file. It's tiny. It's been around for 10+ years. WTF? |

Posted 3 Sep 2011 by Ray_GTI-R
Post: The only way to get your HD3850 crunching is to use a third-party application, and even then the only one that will work for your GPU is the "hybrid" app that uses the CPU for most calculations and the GPU for a few calculations on AstroPulse-type workunits only OK, I think I understand that hybrid means Lunatics. Which I'm running very happily. And that's why GPU temp/load/fan run very low when other GPU-intesive projects are disabled. Very incisive. And very polite, thanks. Summary. It seems that I am now happily running SETI WU's using my GPU via Lunatics (only works with AstroPulse, very little GPU load) whilst other heavily-GPU intensive BOINC projects complete really quickly. Sweet. If I've got any of this wrong, please PM me. |

Post: Thanks very much for your reply. In order for SETI to send work to a host, it must be identified and make a work request.OK, I think I understand that. If you were getting messages about "No usable GPUs found"No, I have never had these messages since the HD3850 card was fitted. and were not using the Lunatics optimized appOK, I was not using the Lunatics optimized app . Where does that leave me. please? To anyone who may be interested ... here's a good read ...http://www.career.virginia.edu/media/attachment/Business-Etiquette-Essentials.pdf |

Post: The HD3850 can process SETI AstroPulse tasksummm does this mean that the original "ghost" aborted original non-Lunatics app SETI GPU tasks mentioned earlier WERE genuine, I wonder. Please, don't make misleading statements.Of course not. What good would that do anyone ... I'm here because something I tried didn't work as expected and need advice. FWIW Personal insults are unwelcome on ANY forum irrespective of eminence.* But you didn't quote one.? Every time SETI starts and a non-usable GPU is encountered SETI says so. This is what the whole thing looks like:Sorry, I get nothing like that. Looks like you just like to make wrong assertions*Please understand that when anyone makes an un-called-for judgement about my decision making ability etc then decides to makes it public without the courtesy to contact me, privately, beforehand I take deep offence. |

Post: I'm pretty sure the "No usable GPU found" message is a generic BOINC messageI was very careful to say ... BOINC log SETI messages you need to refer to that developer's release notes Versus project messages hmm ... Anyway, I'm over all this. I don't want to waste anyone's time any further. The HD3850 cannot process SETI GPU tasks. Period. End of story ~~~ unless SETI sends GPU tasks for the HD3850 on the "sensitive" PC to process, which it might do, automatically, with no input from me. Thanks, again, everyone for your valued feedback, time and effort replying to my original post here. Ray I am now unsubscribing from this thread. |

Post: Thanks for the tip - I already run MW@H. Finding the info you indicate is easy. SETI automatically checks the GPU and if it's unusable for processing SETI GPU tasks (precision/driver etc) it says so in the BOINC log SETI messages ... something like "No usable GPU found". FWIW the HD3850 passes the automatic SETI GPU check and all other projects recognise it, since no such messages appear in the log for other BOINC projects. Maybe I have (again) got the wrong interpretation but that's what I've seen & understood prior to fitting the HD3850, specifically 3 other, very old cards AND a brand new HD4670 were all rejected because they were single-precision. Aside:- this PC runs an AGP interface, althought I believe that the type of interface is irrelevant for GPU-intensive tasks. HTH, Ray |

Post: I bought the HD3850 (512mb) because it has double precision that SETI requires for standard GPU tasks. That was my only reason for spending a LOT of money (and >4weeks' wait) on this card. Also, I read somewhere on Tomshardware that it outperforms the previous card I had - a 1GB HD4670, single-precision - by about 5% in a summary of real-world situations. If there is no pre-existing way to run SETI work on this card then I have misunderstood, and will contine non-SETI GPU work, probably using a card that costs 1/3rd of the price of the HD3850. I doubt that HD3xxx, even with DP, was good investement ... especially for SETI.It appears I have wasted everyone's time, here. |

Post: As before, I thank everyone for their close attention to detail and precision when replying. I'm now running Lunatics Unified Win32 v0.38 AstroPulse v5.05 (ATI) Option ... ap_5.06_x86_win_SSE_BROOK_NO_DOUBLE_r453 All SETI tasks are now showing "Local: setiathome enhanced 6.03" WU progress is better than normal, I think. CPU usage is incredibly low, which is what I want - two processes are concurrently running, named AK_v8b_win_SSE_p3.exe @ 5%~20% of a Gallatin set to 10% CPU * both HT cores running. Normally SETI CPU tasks overload the 10% per-HT core limit … a LOT. GPU AVERAGE values, nothing else running, via GPU-Z 0.5.4 are:- GPU/Fan/Load 38.6C/33%/28% (I run VDDC at 0.974 and a modified fan speed profile, set using ATI Tray Tools v1.7.9.1557.) Is this all magic? I've let things run for 23 hours unattended. FWIW When I started other BOINC GPU projects ... ~ Lunatic kept going even through 90%+ GPU load required by the other projects ~ As usual with tasks from other BOINC GPU projects all hell broke loose with fans & temperatures. dnolan said:- c:\temp\clinfo\clinfo.exe ... Run ... "cmd" .. enter, [to] open a command prompt. Yep. You'll get a lot of info displayed to screen etc. Nope, I get an error message as follows:- Microsoft Visual C++ Debug Library [window name] Debug Error! Program: ... clinfo.exe This application has requested the Runtime to terminate in an unusual way. Please contact the application's support team for more information. (Press retry to debug the application) When I press retry I'm dumped back into the CMD window with no other info. Perryjay said:- a) ... you just got them mixed up? Yes - highly likely, on reflection as I've seen no further ATI GPU-only tasks from SETI for days now. b) ... With that and a modification from Raistmer could run APs on your GPU ... OK, I'm game - what now? Ray PS ... Granular description of my original issue:- In Lunatics Unified Win32 v0.38 Setup AstroPulse v5.05 (ATI) Option ... ap_5.06_x86_win_SSE_BROOK_NO_DOUBLE_r453 & will use extra CPU as well. I interpreted the NO_DOUBLE as not using double precision during GPU tasks (the HD3850 is a double precision GPU) and that where double precision is required it will use the CPU instead. Which is not why I have just paid for a HD3850 (AGP) card to process SETI GPU tasks on this ancient PC. |

Post: WOW! Thanks so much. I understood all that :-) and am truly impressed with the level of detail in the reply and the care in explaining the issue in the clear. I will try out a non-sensitive PC as advised. FWIW I'm confused about two things:- first, the (4, thanks) SETI tasks I thought were GPU tasks since I'm pretty sure they showed as ...ati14... and second that SETI recognises a usable GPU on that PC. Maybe I misunderstood both indicators? FWIW2 I haven't received any similar "GPU" tasks automatically from SETI since my last post so I guess I must have misunderstood. Thanks very much, again. |
