OK !!! Hi Tom ! Go the Nvidia configuration panel. Go to 3D parameters here Go to Configure multiple Graphical Processors, Surround and Physx (Note that this a translation from french to english: my panel is in french ;-) ) Then on the right panel, select Disable (or deactivate) multiple graphical processor mode As a result there must be , at the bottom of the panel, a sentence saying that all graphical processors are operating independently. Hope this helps... ____________ Lubuntu 16.04.1 LTS x64 | |

OK !!! Many thanks for responding. I have Nvidia Control Panel 4.4.370.0. There I clicked "Manage 3D Settings", which gave me two tabs: "Global Settings" and "Program Settings". Here ya go: I see no reference to SLI there... I'm really getting desperate over video performance while GPUGRID is running. Most of the day I have to suspend BOINC. ____________ | |

If your card is not a factory OCed one , I suggest you come back to factory settings and see what is happening... Thanks. OK. Did that. We shall see... But... is there not a setting that will let me select how much - how little - GPU power is devoted to BOINC?? ____________ | |

To my knowledge there is actually no paremeter to limit GPU usage in terms of power percentage. Only the CPU power usage may be limited. Keep us in touch ... ____________ Lubuntu 16.04.1 LTS x64 | |

I've been suffering this problem for months (ASUS GTX 460 OCed, Win 7, 8 CPUs)and it's getting so bad now that I've been reluctantly forced to stop GPUGRID processing. I do hope someone will, sometime, come up with a solution and post here. | |

I may, just..., have fixed the problem! It made no difference to the poor performance. I've been giving my spare cycles to projects since May 1999, for the last three years to GPUGRID, so it is with great reluctance that I have decided to call it a day. ____________ | |

If you select to not use the GPU when the system is in use, and the display performance is still poor, then the problem has nothing to do with running GPUGrid tasks, as these are not running when you are using the system. | |

tomba : skgiven : Hi tomba, I agree with skgiven, I did not notice trhat you are connected through HDMI, this is what is shown in your control panel), to a SAMSUNG S22B350 Full HD 22" LED Monitor with VGA and HDMI capabilities. Can you try connect it through VGA instead , using a DVI to VGA adaptor (normally delivered with the card) and see what happens ? I don't really know how it works with hdmi on the card side but who knows ? ____________ Lubuntu 16.04.1 LTS x64 | |

So you are saying the tasks keep running, when you start to use the system? Yes. Perhaps you missed my comment below the pic: "If I open BOINC in a small window and start Chrome in another (opens 15 tabs in about 15 seconds), BOINC's progress % never waivers. It just keeps on going." If so, what sort of installation did you do; a Boinc service installation, fresh installation or upgrade? Having uninstalled BOINC a month ago I downloaded a fresh copy (7.0.28). I would try setting the "While processor usage is less than" to 10% Did that. I just finished a WU - no impact on performance. The current WU, though running 100% of the time, has no impact either. ____________ | |

By the way did you read my remark above about HDMI vs VGA ? Yes , but your monitor seems to have one. You must use a DVI to VGA adaptor normally delivered with the card if you bought it new...! So you will be using the one of the DVI output of the card plugged to the VGA input of the monitor through the adaptor . You will of course need a VGA cable between the adaptor and the monitor... . ____________ Lubuntu 16.04.1 LTS x64 | |

Are you running any CPU tasks on that system? No. The recommended power setting is Prefer maximum performance. OK. Did that. If the first thing you do when you start using your system is to load 15 web pages, this probably doesn't give Boinc enough time to suspend the GPU task, which means unloading and writing it to disk (GPU tasks are not kept in memory). If the 15 web pages contain Java or flash then they are going to be resource (HDD and RAM) greedy. But if BOINC is obeying my settings, in 15 seconds it must have time to at least stop the running WU before doing its housekeeping. No sign of it doing that... I think this is a general Boinc problem (from legacy designs) which is being exasperated to some extent by task types (size), but largely other programs (browsers), hundreds of operating system updates/patches and of course drivers that are aimed at the most recent cards. Did that. No difference. Seems to me that that some WUs obey my BOINC settings, some don't. Surely that points to a GPUGRID problem?? I'm now keeping a log of which WUs affect performance and which don't. ____________ | |

I did not know that, after unchecking "Use GPU while computer is in use" in BOINC / Tools / Computing Preferences / Processor Usage, I had to activate this preference in BOINC / Activity by checking "Use GPU based on preferences". I had similar problems, with freezing screens or WU'that error out after 15-20 hours running. First thing I did was downgrading my nVidia driver for the GTX285. That helped a few weeks, then it happened again. I found out that Windows was trying to update some software for the graphics card. I have disabled that and now it runs fine. Same option as you, GPU based on preferences. But my preference is "Run always". And it does without problems so far. ____________ Greetings from TJ | |

Certainly not perfect! I ran as above for five days. Every day I had two or three PC lock-outs - it was dead - it was big-red-switch time. So I'm now running as before, and aborting NATHANs that kill my PC performance. Hello Nathan - are you listening?? ____________ | |

I have had the same problem (NATHAN units only). They can not run on GTX460 while you're using computer without making computer nearly useless. If I may add my 2 cents. I'm currently running 4 GTX460 (768MB) GPUs here. All WUs run perfectly except for NATHAN. The NATHAN WUs run at half speed on all 4 of the above cards. It should be rather easy to up a different queue for the NATHAN WUs by using a unique exe name and allowing us to choose whether to run them via a check box in our project preferences. | |

The long runs NATHAN make my PC graphics laggy. The short runs don't AT ALL (you can't even tell you are running GPUGRID with the short runs), but given the 150% bonus for sending a long run back, I'm sucking it up (I get around 1.5 credits/second with the long runs versus ~0.7 credits/second with the short runs). | |

I vote for NOT decreasing the speed of the NATHAN units. IMO they should be coded to run as fast as possible and it seems NATHAN has figured out how to do that. The display lag seems to be an issue with the OS/driver interactions. If it makes your system unusable I would suggest running the standard work units (short) or unchecking "Use GPU while computer is in use." | |

I have been crunching Nathans WUs with 2 GTX460 (1GB GDDR each if I remember well) on 2 different systems (Win and Ubuntu) and then on one system with both cards together : I never had this problem with Nathan's WUs. Things have changed. The last time you connected with your 2 GTX 460 boxes was March/2011 and Feb/2012: http://www.gpugrid.net/hosts_user.php?sort=rpc_time&rev=0&show_all=1&userid=57540 Now you're running a GTX 690 & a GTX 590. Your GTX 590 shows 28 "errors while computing", 27 of which are NATHAN WUs, and your current GPUs are among the ones that actually work better with these WUs. Upgrade our GPUs? They work very well with the other WUs. How about upgrade the programming... | |

How can you explain that, for the involved WUs, not everybody with this kind of GPU is affected. If a WU is badly programmed it will affect a lot of different kinds of GPU. No sir, I'm not a banker ,lol , but some put their money in a house, other in a car etc... It' s just a matter of choice...

I've looked at the results from dozens of them. They're one of the more common GPUs being run and the NATHAN WU performance is severely degraded on all of them. Bad for the project, bad for the users some put their money in a house, other in a car etc... It' s just a matter of choice... So we're supposed to buy video cards instead of a house or car?

Hello Nathan! Welcome to our thread (at last!!!). Sorry for the late reply. I did not know about this thread until a few days ago, and I just got around to replying now. The original subject matter wasn't directed at me, and so I wasn't following it. There is a moderator posting to this thread. I would have thought that he/she would have notified the concerned scientist (you) in less than the five months this thread has been active. As Bjarke and TheFiend have said, the likely issue is that the 460 does not have enough memory. My simulations are typically of larger biological systems than those of the other scientists, meaning more on-card memory is required for them. If the entire simulation can't fit on the card memory, a secondary algorithm must be used which is slower. There is not much we can do about this. Slower... (?) However, I don't think that it results in a 50% slowdown (1/2 speed). That is not the issue here. I absolutely don't have a problem if my modest GPU hardware causes a slowdown of your WUs. What I and many other volunteers are experiencing is a lock-out of our PCs. Normal Windows operations take 10-times longer with some of your WUs. Tomba, That's me! for your case specifically, I have pulled some stats from the database (for the period from Nov6 to Nov19, the period I could query right now): That's all very well, but did you also notice that, in that time period, I aborted no less than 30 of your WUs because they were killing my PC performance? Dear Nathan. Pretty please, have another look. Thank you, Tom ____________ | |

Hello Nathan. Thank you for your insights. (1) You have one GPU, which is naturally your display card as well. You are attempting to crunch GPU tasks and use the computer at the same time. This is generally not a good idea with an older card where your display requirements are heavy, especially when watching movies or doing 3D work I don't do movies or 3D work. (2) if there isn't enough memory on the card for the WU, then the program/OS will look to your system RAM, and then to the swap memory (Virtual memory on Windows). I have one gig on the card, and six gigs of RAM driving an i7. Right now I'm running I6R9-NATHAN_RPS1120913_respawn2-65-100-RND8231. I don't have a performance problem. Here's what my gadgets tell me: I guess I'll wait for a killer WU and report again. FYI, in the past two months I have had one non-Nathan WU that killed my PC: 2CN4_3-GIANNI_bias-11-25-RND1144 ____________ | |

This thread started off as one of several threads about the 3.1 vs 4.2 app. It then went to SLI and while not quite hi-jacked, as the initial problem was solved (and the title fits), it’s moved onto what seems to be a general complaints thread, about performance issues and limitations of the GTX460, amongst other topics. | |

Perhaps CC2.1 for short tasks only?I do NOT agree with you. I have got one of the first GTX560Ti CC2.1 1023MB and I have no problem on 64bit XP crunching any longrun task. Some teammates have GPU CC2.1 with memory over 1,2GB and they did not report any problem in our forum or here. By my point of view there is no reason to disable longrun tasks for CC2.1 due to problem of one or several specific systems. In all I agree with you, especially in point of necessity to specify system having problems exactly. Off Topic for tomba: How do you like WCG HCC GPU tasks on nVidia GPU? | |

As Bjarke and TheFiend have said, the likely issue is that the 460 does not have enough memory. My simulations are typically of larger biological systems than those of the other scientists, meaning more on-card memory is required for them. If the entire simulation can't fit on the card memory, a secondary algorithm must be used which is slower. There is not much we can do about this. In my tests it's almost exactly a 50% slowdown on the GTX 460/786MB cards. It's a memory size problem since the GTX 460/1024MB cards do not have the 50% performance hit. ON the longer NATHAN WUs there's no way to make the 24hr deadline with cards with less than 1024MB either. The TONI WUs run in 12.5-13.5 hours on my 4 GTX 460/786MB cards. As suggested, a solution would be a separate queue for WUs requiring a large memory footprint. Should be simple to implement. | |

Well I have a GTX285 with 1Gb of memory, Vista x64 ultimate and driver 285.62. | |

For Tomba: perhaps you can check with process explorer (from Microsoft, free to download) if other applications are occupying your system. I think that the four examples I've posted of my system state when GPUGRID is running amply demonstrate that nothing unknown is occupying my system; pratically no CPU activity and <50% system RAM usage looks good to me! But I will give Process Explorer a whirl... Tomba ____________ | |

Ok, I think a lot has come out of this thread, both with the original troubleshooting about display performances and the user concerns about performance and hardware capabilities. I am heading off on holidays tomorrow, so here are my final comments, at least for this thread. (skgiven) I think it’s important that the researchers specify the requirements for various task types, so people can opt in or out of the project, or for long or short tasks. Of late we have had some heavy GPU memory requirements for several lines of research, some WU’s requiring too much CPU to facilitate even a mid-range GPU and untested release failures. Not much point adding Twitter if you can’t Tweet the basics in the forum! (Beyond) As suggested, a solution would be a separate queue for WUs requiring a large memory footprint. Should be simple to implement. I think these are all valid concerns, and we'll discuss how to address them in the new year. Making modifications to how we send tasks or adding a new queue (or however we address the issue), is not a trivial task, since it requires we modify the server. Modifying the server can cause it to crash, or it can lead to loss of data. "Small" changes can turn into catastrophic failures, and we'll have to test them first. The high memory usage NATHAN work units will disappear from the queue in the next week or two, so that will no longer be a problem. I will submit some more WUs soon, but they will not have high memory or cpu usage. We'll try to figure out how to handle those types of work units better in the future. Now I'm off for the holidays. Merry Christmas, happy holidays, and happy new year to everyone! | |
