Number crunching :
Machine generating bad results.
(消息 1534714)
发表于：2 Jul 2014 作者： tbret Post: ps the machine I am now using is only 7 days old and only run seti for 2.5 days AMD FX 8350 chip GTX 650 nvida 16gig ram Glen, if you built that computer there are lots and lots of stories about motherboard manufacturers saying their boards will run "FX Series" CPUs that don't go-on to say that does not include the FX-8350. If you built it, you might want to consult the approved CPU list for that motherboard. Apparently manufacturers are "retracting" some of their claims. The FX-8350 seems to be giving some people fits with how much power it wants to draw, so the obvious other question is; Even if the motherboard manual says the FX-8350 is compatible, do you have enough power supply? And then the other obvious question is, "Do you have enough fans to thoroughly cool your case's air?" Blowing hot air over a hot heat-sink doesn't do much good. Although I run three FX-8350 machines, I am not crunching CPU work units on any of them, so any comparison with my computers would probably not serve you well. I will tell you that none of mine are using the stock heat-sink and fan. I learned that lesson a long, long time ago - I mostly couldn't stand the noise of those little fans blowing at take-off speed. |

I'm sorry, but the fact of the matter is that unless I have some idea of what hardware you are running on what OS, I'm lost. That doesn't mean that others are lost and you might get some help. It's just that I can't even begin to guess what the problem might be with only the information you've given. You've described the problem, but with your computer hidden we can't see any symptoms. |

Considering new Graphics card
(消息 1534699)
发表于：2 Jul 2014 作者： tbret Post:
I have a question, then maybe a suggestion. Why are you going to replace the 460? Is there something wrong with it, or are you tired of looking at it, or do you want something that's better for games, or... what? Recently I let one of my two 460s go with a machine I built for a friend, but the other one is chugging-along just fine, crunching like it always has. Based on crunching one AP at a time, the 460 is taking about 2,200 seconds to crunch-through an AP task. A brand new (I just installed it) AMD R9 270x seems to be doing a single AP task in 2,000 seconds. Both of those measures are "more-or-less" but close enough. What I'm about to tell you is patently unfair, but you might find it useful. My 660Tis seem to be running *two at a time* in about 4,500 seconds using the Lunatics' optimized applications or about 2,250/work unit. I honestly think it would be unfair to say they wouldn't run faster than that if they were doing one work unit at a time. On the other hand, the 660Ti never impressed me. It must not have impressed anyone else, either. They have gone away. One of my 750Ti's is doing a single AP in about 5,000 seconds. The other one in a really old P4, but running XP instead of Windows 7, is doing a single AP work unit in about 4,500 seconds. Okay, conclusion: If I were shopping for a card in that price range I would be looking at either a AMD R9 280 (to get the 384-bit memory) or a factory superclocked version of the GTX 760. Now the question is; Do I have a heat problem? If yes, then I'd probably go with this one or the equivalent because it blows hot air out of its... exhaust: Overclock 760 If no, then I'd give some serious thought to the R9 280. (notice there is no "X") HOWEVER --- You know what AMD drivers are like. The AMD would probably be really good at some of the Einstein work. I don't have any idea what's best at the other projects you run. Congratulations on spectacular finish. |

Okay, two quick comments: A common misconception is to leave a hardware core free to feed a hardware GPU. The actual balance is between the *number* of GPU-tasks running and the "free core" count. It's entirely possible to run 4 GPU-tasks and cause a traffic-jam at the CPU/memory/bus, but running three might not, or two might not, or you might be able to get away with running four if you allowed four cores (I realize you only have two) to work on a single GPU. And, unfortunately, this changes with the type of work you are running. Clarification: I wasn't talking about one AP and 2 MBs. I was saying you can set things to run 1 AP; or 2 APs, or 1 AP and 1MB; or 2MBs; (depending on the work you have) without your having to do anything but set it up that way to begin-with. Yes, SETI work is a little hotter to run than Einstein work. Currently. Of what's available. You can set things up to run one Einstein work unit and one SETI work unit, too, just by taking the way Einstein works into account, but like here with the MB and AP difference, the different tasks at Einstein run differently so you can't just say "1 Einstein and 2 SETIs, please" unless you specify which Einstein and which SETI. And you can probably reduce the CPU-stress a little by using a few command line switches in a TXT file in your project data folder - AND - there's another version of an application that you would have to manually install to get full benefit of that. It's not hard once you understand a very little (that's all I know) about what you are doing. I'm not trying to convince you of anything. I'm trying to let you know that these things are possible. What is best for you and your system is something about-which I have no opinion. How could I possibly know what's best for you? I can't. Heck, I haven't even settled-on what's best for me, yet. And I'm about to embark on a new adventure with some of these machines and add yet another one or two (just for that adventure - I would already be divesting myself of machines if it weren't for this "new thing" I'm going to try for a little while). Enjoy the double-crunching! I suspect you are going to find that either two or three GPU work units are optimal and you could let both cores of your CPU feed that without bogging-down your machine for other things, but that's a guess based on what I see on a P4 with Hyperthreading. I find that I can generally do two APs or 1AP and 1MB or three MBs to give me the optimal throughput, but I don't own a 760 on XP, so that may also be your experience, or maybe not. If you haven't downloaded and installed SIV (System Information Viewer) yet, I'd encourage you to do that. It's a great way to see everything you need to know (temps, usage %, fan speeds, etc) in one quick place. |

AP elapsed resetting?
(消息 1532909)
发表于：27 Jun 2014 作者： tbret Post:
If I knew for certain what that meant, I might be able to comment. Do you mean that AP "time elapsed" is resetting as a work unit runs? Are you confusing time "elapsed" with "time to completion" which is a different, known, thing. Are you new to AP so that your estimated crunching times are way, way off the mark and are adjusting? If you were being specific, I think I'd reboot the machine from a cold start. But "why" it's doing that I can't guess without being able to see the machine or without your telling us all about it including hardware, driver, BOINC version, stock-or-lunatics, etc. |

GPU Wars 2014: Postponed to 2015?
(消息 1532904)
发表于：27 Jun 2014 作者： tbret Post: . I look forward to the next round of cards, although I probably won't be an early adopter. (because of the prices) I'm not finished making comparisons yet, so please don't quote me, but it looks as-though the 750Ti cards I have perform about the same as a factory overclocked 550Ti. If, and I want to emphasize IF, that's true, then there seems to be a significant power and heat savings per unit crunched in that "range" of cards. If that holds true of the more powerful cards, this might be a real motivator to replace some older cards, even if the old ones are still working well. |

(消息 1532890)
发表于：27 Jun 2014 作者： tbret Post: It runs, it LIVES!!!!! :-) Even-so, you might be able to run harder and live better if you want to get into it a little. You are crunching on a good GPU supported by a fairly low-power CPU. If you look at my machines you'll see that I've got some situations that are even more lop-sided because old P4s and Athlon 64s are what I had laying around. There may be some things we can do to increase your effectiveness AND (importantly in your case) reduce the stress on the CPU. IF you want to pursue them. If you don't, I can definitely respect that. In any case, I'm glad that you got it running the way you want it to. EDIT: You can probably crunch two APs at a time without bogging the machine down (although you won't gain much) by adding a line in another file we haven't even talked about, yet. But the biggest over-all gain you may experience is by setting things up to run one AP or one AP + one MB, or two MBs. I was going to ask if you wanted to try that and eventually get things to that point. Since I don't have a machine just like yours, it might take some experimenting to let you decide how you felt you wanted to run. |

发表于：27 Jun 2014 作者： tbret Post: Tbret. I don't think you got anything wrong. I don't know where that comment came from. I think you've done a GREAT job and the stand-alone downloads are a terrific service. Thank you. I wasn't bashing anyone or anything. I just need to know exactly where TimeLord04 stands, obviously. BTW - I was talking about another place you can download an older version. I won't mention it here so that nobody goes there. |

发表于：27 Jun 2014 作者： tbret Post: Somebody remind that on the next installer I double the size of the line that says where you can download it... What? So we can read where to download it after we've installed it? Huh? But did YOU do the last installer? Very nice. I've used it many times and always admired it. Problem is, I think there are old versions still downloadable out there and the easiest way to tell which new version he has is to look at what it installs. You know, so I know for a metaphysical certainty what I'm dealing-with before I start trying to be "helpful." There's nothing worse than being told to go to line 16 and remove the asterisk only to find that there is no line 16; but having someone yelling at you, "Of course there's a line 16!" like you're an idiot.
You'll be the first person any of us thinks-of if we need debugged. Promise. |

发表于：27 Jun 2014 作者： tbret Post: I'm guessing you gave-up and went to bed. I've got to do likewise. We'll get this straightened-out and once we do you'll understand what you are doing and won't have any more problems getting your new machine to act like you want it to. Optimizing it exactly for the mix of projects and work you want may take a while, but it's doable. Chin up. Say "hi" to K-9. |

We're going to solve this, pretty-much now. It's just not that hard. The problem at this point is that we've gone so far that I'm not sure where we're starting-from. So, we start at first principles and move-on. The problem, now, is that there are at least three different versions of AstroPulse included in different installers, so the only way I know how to find-out where we are, for sure, is to start-over. |

发表于：27 Jun 2014 作者： tbret Post: Oh, it's getting frustrating, isn't it? What do you *want* to run on what processors? For right now, do this, please: Stop BOINC and all its running processes. Go back to your Lunatics installer. Install it. Right after that, without changing anything else, copy the following, paste it into a notepad document, save it as app_config.xml into your project data folder. Don't edit it or try to optimize it. Yes, there are lines and entries you don't need and there may even be something you do need that's missing; just copy it and put it in your project data directory. If it doesn't work the way you want it to, we'll cope. <app_config> <app> <name>setiathome_v7</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>0.48</gpu_usage> <cpu_usage>0.04</cpu_usage> </gpu_versions> </app> <app> <name>astropulse_v6</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>.50</gpu_usage> <cpu_usage>.5</cpu_usage> </gpu_versions> </app> </app_config> AFTER you do that, please copy and post your app_info.xml here and stand-by. If you can do it soon enough, we'll get this straightened-out pronto. |

发表于：26 Jun 2014 作者： tbret Post: I changed "Max Additional Work Buffer" to 7 Days from 3 Days. Updated all projects; and SETI downloaded a BUNCH of work!!! :-) Beta downloaded nothing; probably it will now wait for both SETI and Einstein to get lower before downloading... Einstein also did not download anything new, yet... Well, just so you know - nothing works the way you think it does with work-fetch. I can't call it an error, because I don't understand it, but Einstein "tends" to be "greedy." BTW - Einstein isn't greedy. BOINC is responsible, not Einstein. It just "looks" like Einstein is greedy. The way I've had this explained to me in the past was: "Leave it alone and eventually BOINC will figure-it-out and you will get about the mix of work that you have set over the long term." That's a satisfying answer, but not an acceptable proposition (for me). The whole scheme was set-up to work with "Set And Forget" screensaver / background / I'm-not-all-that-involved users who don't want to goof-around with their settings once set. You know...sane people... people with a life... So, while I'm sure it is true that if I set a 10:1 preference for SETI work and just kept the computer housed and fed, eventually it would all work-out; I'm not likely to keep my fingers off of it long enough to see that happen. It's people like us that cause unrest in the ivy-covered-hallowed-halls and ivory towered castles in the sky. Those poor folks have to figure-out how to make sure that all the stuff we do that they never intended to be done doesn't bring the whole thing crashing-down on the heads of less "fiddly" users. But don't be surprised if you had a 50/50 mix SETI/Einstein and you set ten days as your work cache (I don't recommend that) if Einstein initially downloads almost ten days' work and then shifts into "high priority" leaving whatever SETI you may have-had sitting there for a long while. I've never had the patience to let it average-out over time. Anyway, as you've discovered you can run out of disk, run out of cache, run out of time-to-completion, etc, etc, and work fetch will stop. (if everything's working as it should) No need to panic. Eventually the TARDIS will find its way home. |

发表于：25 Jun 2014 作者： tbret Post: Is there anywhere to see how many, if at all, suspicious signals are detected? This particular choir has been singing in full-voice FFF for some time, now. Keep in mind that these academic endeavors are usually commented-upon only in peer-reviewed papers meant for publication. While I am almost desperate for them to break their silence and say something, anything, about anything, or write something about nothing, I understand that they have a duty to their institution to be very professional about whatever they say. "At some point in the future there will be a paper written about anything we find of interest in the present," may not be satisfying, but it may be what we should expect. http://setiathome.berkeley.edu/sah_plans.php An update there would be nice since much has changed. Maybe there aren't updates because they are all busy writing papers for peer review! |

发表于：25 Jun 2014 作者： tbret Post: I'm using 7.2.42 with Wiv7/64. Something Hal9000 said hit a chord. I recently installed a wireless dongle for some tests, and the issue started after that. So I disabled the dongle aqnd the problem hasn't reared its ugly head since ;-) I don't know that this has anything to-do with anything, but a recent Windows update seemed to kill the onbaord LAN on two of my computers (different motherboards, but maybe the same LAN IC ) and only a restart would fix it. Other identical motherboards were not affected. I'm guessing something "grabbed" an IRQ the LAN wanted, but it's only a guess. |

发表于：24 Jun 2014 作者： tbret Post:
It is as you say, but it is worse than that. I log in and BOINC starts. I switch users and BOINC stops. I switch back to my account and BOINC reports missing GPUs. I have to stop BOINC and restart it and the GPUs come back. The act of switching kills the recognition of the GPUs by the driver... or something. There really must be a combination of scheduled task (start BOINC in the background) plus a registry hack ("There is another instance of BOINC running on this computer....select and log in") that would work. I can (and have) installed BOINC on the primary user's account, so there should be a minimum of switching back and forth. When I say "a minimum" I mean once in a blue moon. The staff all pretty-much hang-out at their own desks. It's really a non-tragedy, but you would think that since the OS is designed to allow for multiple users, and with an option to "allow all users to control" that this losing of the GPUs behavior would not be an issue with BOINC. It is what it is and I'll cope, but it seems odd to a guy who doesn't understand how the applications interact with the driver. If I understood a little more the issue might seem obvious. Thanks for thinking about it, but don't blow a fuse or anything. It's not a big deal. |

发表于：21 Jun 2014 作者： tbret Post: Ok... I'm on a real keyboard so I thought I'd see if someone can tell me how. There are four computers at my wife's office that now have some of my GPUs in them on a fresh install of Windows 7 Pro 64. Those computers are connected via LogMeIn Pro so that I can run Malwarebytes, CCleaner, etc, and try to keep them in reasonable shape for the office applications that run on them. That also allows me to get to an account I have for my access to them in the event a user gets locked-out, etc. Now, the users won't mess with the BOINC setup I have on those accounts so I could simply put BOINC in their accounts. I will probably select the most likely long-term user and install it there. They WILL most likely change the screen saver and other personal things, so making BOINC re-start as the screen saver is probably not a good idea. I'm not in a position to tell them not to change it. But it would be handy if I could somehow install or run or whatever BOINC from MY account and not have to install it in every account that may be on every computer, then potentially have a different user log-on for just a minute or two, then have "GPU missing" come-up and have me not notice until enough time has passed to notice the machine has stopped checking-in. Now, I realize that all of this is a tempest in a teacup. It isn't a tragedy if some completed work units aren't returned for a few days. It would just be nice not to have-to worry about it. Edit: By the way, I'm not trying to "get away with" anything. My wife knows about this and while she rolls her eyes a lot she does not really care one way or the other so long as she gets "computer support" from me when she needs it. Obviously, the support she gets from me is basic user-level stuff, but that's far beyond the staff. Sometimes I wonder how they manage to feed themselves. I guess they buy a lot of new computers for themselves. |
