6.11.1 Released to Beta - Notes?
(Message 34036)
Posted 2 Aug 2010 by skgiven Post: I see lots of comments about "Attach to Project" vs "Add Project". If it's not broke... WRT "Consider aborting it" - Please, NO! The Lattice Project, for one, would not be too pleased. They are running with small time limits and tasks that last much longer than expected; it would be to their downfall. Perhaps something more hands on (useful) such as, Refer To Project for task duration and Run Time Advice, or a better suggestion if someone can come up with one. Thanks, |

(Message 33811)
Posted 18 Jul 2010 by skgiven Post: I would like to be able to use foldit (a most excellent program) and still use my GPUs; I have 4 GPUs in one system! Foldit uses the CPUs but not the GPU. When I am working with large office files it would be really useful to be able to free up the CPU cores for a few minutes (when a client needs something urgently) without interrupting the GPU tasks. |

Posted 17 Jul 2010 by skgiven Post: Just add a feature to suspend all non-GPU projects. You can already suspend individual projects, so all you have to do is amalgamate this into one handy feature. |

(Message 33800)
Posted 17 Jul 2010 by skgiven Post: Within Boinc's Advanced Preferences there is a processor usage Tab, under which is the solitary GPU control, "Use GPU While Computer is in Use". I would like to be able to keep a low cache for GPU projects, and a higher cache for CPU projects. At the minute this cannot be done. For GPU projects it is important that tasks are reported immediately, whereas with CPU tasks this is undesirable in some cases. Some people want to run GPU projects on one card but not another, using their slower card for display and their faster card for crunching. Such advanced configurations are difficult to arrange via the cc_config file, and requires advanced user skills. At some stage the introduction of separate CPU and GPU Tabs with several selections might facilitate such configurations. One of the better introductions was the Snooze GPU (from the taskbar). Would be nice to have a snooze CPU function as well. Sometimes we just want to use the CPU for other programs, but would prefer to allow the GPU to crunch. Presently the only way to do this is suspend individual projects and then restart them. However some projects use both CPU and GPU (well, did at one stage). |

Fermis shader count - how to

Posted 16 Jul 2010 by skgiven Post: NVIDIA GPU 0: GeForce GTX 460 (driver version 25856, CUDA version 3010, compute capability 2.1, 738MB, 363 GFLOPS peak) - The reported 363 GFLOPS peak seems a bit low for a card with 336shaders and 675MHz cores. It should be 907. http://en.wikipedia.org/wiki/GeForce_400_Series |

Fermis shader count - how to
(Message 33774)
Posted 15 Jul 2010 by skgiven Post: The number of shaders are being reported incorrectly for Fermi cards by Boinc. To get the correct shader count multiply the multiprocessors count by 32 for GF100 cards, and by 48 for GF104. GF100 cards are GTX480, GTX470 and GTX465. These have 480, 448 and 352 shaders respectively. The GTX460 has 336 shaders grouped in clusters of (3x16) 48, unlike the GF100 cards that are in groups of 32 (2x16). # Using device 0 # There is 1 device supporting CUDA # Device 0: "GeForce GTX 470" # Clock rate: 1.41 GHz # Total amount of global memory: 1341718528 bytes # Number of multiprocessors: 14 # Number of cores: 112 (this bit is wrong, still) Number should be 14 x 32 = 448. |

(Message 33722)
Posted 9 Jul 2010 by skgiven Post: The main problem remains, that even though these gadgets can play video for so many hours, running any project at full force will eat up battery... Well, perhaps not. These are Extremely energy efficient and if the CPU is used it should be able to crunch for longer than if an HD movie is played on the GPU. Also, they are comming to a TV near you, and sometime soon. In fact Audi have them in a range of their cars (I dont think power will be an issue there). Over to Oded... |

(Message 33718)
Posted 9 Jul 2010 by skgiven Post: Thanks for your reply Jord, You have identified several generic problems, some of which apply and some of which may not, in this case. Glad to hear porting is not a problem for Boinc. I know it would not be to every projects taste, but I would have thought some projects might be interested. A dual 1GHz CPU core that performs about twice as fast as the Atom (per core) may be on the low side, but there are plenty of Boinc projects that don’t need an i7 on OC. WRT heat, it uses 40nm chip technology. They will not generate high temperatures, given the small transistor count. The energy requirements are exceptionally low (compared to an Atom); even a small hand held device, with a tiny battery could play 1080p video for 16hours. Although some projects do require large amounts of RAM (the Lattice Project), most require less than 100MB, and many require about 10MB – next to nothing really. Tegra 2 can support several GB of DDR2. With 4GB Micro-SD being available for about $10, I don’t think adding RAM would be much of a problem either. It also supports USB2. I think the main problem is getting a project to take it on, but even if 0.001% of Tegra 2 users contributed to that project, there would still be about 10,000 contributors by the end of a year, and many of these people would probably contribute elsewhere and in the future (a year or two when Tegra 3 comes out, or a competitor). While many of these will turn up in mobile devices, hundreds of millions will also turn up in devices with permanent locations, such as TV's. It’s hardly fair to say an architecture with a history of over 10Billion devices is Obscure! |

(Message 33716)
Posted 9 Jul 2010 by skgiven Post: Is there a chance a Boinc program could be written for the Tegra 2 (ARM9/ARM11/NVidia computer on a board)? Although it's not x86 compliant, apparently Chrome (a Linux based OS) is set to use Tegra 2. You can see it used with Android 2.1 here. These will soon be in mobiles, ee pads, TVs, consoles, net-top computers and other devices (Prototype). Over the next 18moths it is expected that over 1 Billon will be sold. We know these are very energy efficient but they are not slow either; can outperform an Atom CPU. I guess the dual 1GHz Cortex A9 cores are it's most promising feature, but it is also OpenGL compatible, so perhaps a simplified Boinc app could be specifically written for this Tegra 2 architecture. What do you think? |

Posted 3 Jul 2010 by skgiven Post: Actually No, it was out - by about 5 months! Of course the time was almost exactly correct; just the date was out! Just bad luck there. I expect the system froze due to a power issue and the BIOS went back to its manufacturing date. Thanks, |

Posted 3 Jul 2010 by skgiven Post: Just reporting an update issue with Boinc 6.10.56. Following a rare system freeze (XP x86), I restarted the system and saw that communication to all projects had been deferred for about 3500hours. I did a manual update, of course, and things are now working normally, but I think a 5 months communication deferral is a bit long! |

Questions and problems :
Matching drivers to operating systems
(Message 32825)
Posted 15 May 2010 by skgiven Post: I was having problems at GPUGrid running one of their applications. It turned out that the problem stemmed from an NVidia driver (19745) and what was read by Boinc, and only effect Windows Vista and Windows 7 (both are 64bit versions), not Win XP x86. On Vista and Win 7, the 197.xx drivers are reporting incorrect RAM amounts to Boinc, reporting slightly less values. We think this is causing the tasks to immediately fail (thinking there is not enough RAM). I tried the 19745 drivers on several versions of Boinc from 6.10.18 to 6.10.56, but all were still reporting the incorrect RAM amounts (475MB instead of 512MB). After uninstalling the drivers and installing 196.21, I managed to start running the previously failing tasks, and Boinc reports the correct RAM amounts. Tested on Vista with four GT240's and on Win7 with a GTX260sp216. Again, the problem does not occur on XP x86 with the latest drivers. Perhaps a note on the driver download page to match known working drivers to Boinc applications and operating systems would help others? Boinc suggestions: Would still like a seperate Tab on Boinc for GPU config. Would like to be able to set cache levels for GPU and CPU seperately. Also think that you might want to use different versions of Boinc for different operating systems (given that the drivers are so different, eg between XP and Vista). Might simplify things (development and troubleshooting), and rollbacks would effect less people! |

Posted 20 Apr 2010 by skgiven Post: I didn't extend the monitors after I used the KVM! Now done. So the KVM is sort of working; Unfortunately I am only seeing 3 of the 4 cards in Boic, but that is better than 2. The monitor display is a bit pale and greenish, not good, but usable for now. I have Vista, so its, Right Click on the desktop, Personalize, Display Settings (for anyone else with this problem). Then choose the card and extend the monitor. Display Settings lists 7 cards! (Device Manager is correctly showing the 4 GT240's). So, in Display Settings there are, Four of - (Default Monitor) on NVIDIA GeForce GT 240, and three - Generic non plug and play Monitor on NVIDIA GeForce GT 240 I guess the 3 generic devices are the ones that Boinc can see. Perhaps the KVM cable to the other card is an issue, I will check it again, reboot... Thanks, |
