Windows :
Bionic Not Running Error after "upgrade"
(Message 1369397)
Posted 1 day ago by  Ageless
a) The software is called BOINC. b) The message you get is informative, not an error. c) Please post your start-up messages. You can get those from the Event Log, press CTRL+SHIFT+E simultaneously, post the first 20 to 30 lines. d) Please post the contents of the global_prefs.xml file and if it exists the global_prefs_override.xml file. You can find these files in the BOINC Data directory, by default under Windows 8 at C:\Programdata\BOINC\ It will be a hidden directory, so either enter the path directly into Windows Explorer and hit Enter, or tell Windows to show hidden files and folders. The XML files can be opened with Notepad, no need to use an XML editor (although it's possible if you have one installed). |

What are high priority tasks
(Message 1369127)
Posted 2 days ago by Ageless
BOINC will try to get all work in before the deadline. High priority tasks are just normal tasks, but with BOINC in a sort of panic mode, in which it will try to get those tasks as well as all the others in cache in, before their various deadlines. |

How to show graphics on GPU work
(Message 1369125)
Posted 2 days ago by Ageless
I believe the screensaver is an openGL program, and the CUDA (GPU) programs don't leave enough overhead. No, that's not true. It was always believed that using the GPU and making it show intricate 3D OpenGL graphics at the same time would increase the error rate, but it shouldn't. CUDA has had the capability to show graphics while doing calculations from day one, but the project just didn't choose to use the option. Einstein does have a graphics app for the CUDA and OpenCL applications, showing it's well possible. |

Go to your account, computing preferences and set Suspend work when non-BOINC CPU usage is above x% to zero or 100. When you use local advanced preferences, set it through there. |

An Idea on how to get more people involved with SETI@Home
(Message 1367508)
Posted 6 days ago by Ageless
I think you should attach some computers to this project and run some numbers first, rack up some credit etc. before putting on ideas like that. The credits we have here are of a non-value, and are explicitly of a non-value, so that you can earn as many as you want, without giving you any idea that you with 12 trillion are any better than the next person with only a hundred thousand. That'll change as soon as there's some currency involved, even if this a virtual world currency, it is a currency and it does have dollars worth in the real world. At the time of me typing this, $113 worth. Something like that goes against the principles of this project. And besides, all that the project is asking for is your spare CPU cycles, those that you have left over when you leave the keyboard and the computer idles away. If you were that into saving money for electricity, you'd set up your computer to go to sleep when you were away from the keyboard for x-amount of time. Added to all of that, at the present, the project still has database trouble with the amount of computers it can serve, I don't think it's in their best interest to ask for that many more people with their computers as that'll only add to the overhead. And lastly, a conversation from one of the email lists, with David Anderson, BOINC's main developer. Nicolas wrote: Considering David Anderson is against Bitcoin mining and even more about using BOINC for it, that will never happen. (see boinc_stats mailing list archives) David Anderson wrote: Yes and no. I personally think that using lots of electricity to generate virtual currency is environmentally irresponsible. However, BOINC aspires to support as many types of applications as possible, regardless of my opinions of them. Nicolas wrote: I don't think it's in scope for the BOINC core client to have explicit code detecting eg. BitForce hardware, which is an ASIC only useful for David Anderson wrote: Yeah, I'd agree with that. |

Performance and credits issues with BOINC 7.0.64 (x64)
(Message 1367103)
Posted 7 days ago by Ageless
Can I ask why you are running a 64bit system your gpu only has 256meg of ram and it is not the latest type of GPU do you have 4gig of ram or greater ? You do know you're looking at the memory on his graphics processor? Not the memory that the computer itself is using? That if you go a bit further and check his system, that just the line Memory 4083.89 MB will answer all your questions? You don't run the OS on the GPU. The memory amount on the GPU has only got to do with how big the texture maps are that you can load into memory, or in the case of GPGPU, how many tasks you can run simultaneously. The amount of memory that Windows will use for showing the GUI and such is perhaps 10-25MB, nothing more. |

Questions and Answers :
GPU applications :
Astropulse ATI not stopping on PC use
(Message 1366161)
Posted 10 days ago by Ageless
The Astropulse GPU applications continue to run when BOINC is suspended. That doesn't show up in the stderr.txt file. Only if there's an actual error happening, can we see something in stderr.txt Or if the app would actually write its checkpoints in stderr.tx, perhaps we would be able to check it against the Event Log at the time to see if it wrote checkpoints at the time of suspension. But alas, the AP GPU app either does not checkpoint (anymore), or it does not write its checkpoints to stderr.txt I forwarded the information to Eric and David, especially on the note that the Seti_Enhanced application does stop when BOINC suspends, but only the Astropulse application for AMD and Nvidia GPUs does not. And also stressed it happens sporadically, meaning it's difficult to track. I also think you missed out on Eric's answer in this thread that he did find a bug and is working on a fix. Of course, you're missing out on the email discussion happening between the two devs. David Anderson wrote: BOINC suspends/resumes apps by sending them messages via shared mem; the BOINC library handles this within the app. Eric Korpela wrote: Yes, it turns out there was an unmatched begin_critical_section. I'm working on a fix. Now, if you think you can handle it better, be my guest, go ask questions. I think you're secretly miffed at having your name in the application's output and that you think I am accusing you of misdoings. That you therefore feel it is justified to tell me how I should help people around here. I must say I really do not like your style of posting. Most of your posts and emails come out in an accusatory style, I am not sure if that's what you mean to do, or that it's your lack of understanding of English, or lack of knowledge of netiquette. Perhaps it's time you worked on that. I'd appreciate it if you stop and cease your hostilities immediately. |

New OpenCL. Need some clarification.
(Message 1366149)
Posted 10 days ago by Ageless
OpenCL is intended for GPU not CPU use. Not sure if you mean this in general, or for BOINC or any project. If in general, then do know that OpenCL can run on CPUs as well. Any Intel CPU from a Core Duo to present and any AMD X86 CPU with SSE 2.x or later will do. The next BOINC will add OpenCL support for CPUs. Perhaps that projects will want to use OpenCL for multithreaded applications, over the present MT technology. |

Or set a different IRQ for that slot, in the BIOS. |

Astropulse ATI not stopping on PC use
(Message 1365841)
Posted 11 days ago by Ageless
No, you're not the only one with this problem. I've just posted the following in this thread (you being person 2). Taking into account that two others (person 1; person 2) have reported that Astropulse (on their ATI GPUs) continues when they suspend BOINC, be it through the Activity menu, be it through 'do not use when computer is in use' policies, I suspect that this user has a similar problem. Only with AP on his Nvidia GPU. :-) |

Both have been warned and are on the case. Eric had seen similar problems already, but only with random tasks from other projects. |

BOINC is an environment to manage the SETI@Home applications, suspending BOINC will not necessarily stop the applications running. Then I wonder what will... ;-) But it should. It just doesn't do so on Astropulse applications. Last night I reported two cases of this --though both with the AP ATI OpenCL app-- to the Seti developers, and they're looking into it, to see if it's something with BOINC or something else. |

As said, you don't need to do anything. Your computer's CPU will work on tasks, there's nothing that you as a user needs to do, just keep the PC/Mac on. |

(seti stops correctly its just astropulse ATI that doesn't) Well, that shows it's not a BOINC problem, but an application problem. |

(Message 1364955)
Posted 14 days ago by Ageless
Just an example as to why 7zip is great: its compression over zip. I have a (transitioner-log) text file that's 18,991KB big. Using the 7zip archiver, I compressed it twice. Using ZIP format, compression Ultra, compression method deflate, dictionary size 32KB, wordsize 256, this file compresses to 354KB. Using 7zip format, compression Ultra, compression method LZMA, dictionary size 32KB, wordsize 256, this file compresses to 193KB. We know why we use compression archivers, it's to make these files smaller on disk, but also smaller to download. I'm sure some of us don't mind if a file is 19 Megabytes or 193KB, since we have unlimited download capacity over a big download pipe. But not everyone has that, so when every byte counts towards your cut-off at the end of the month, the better compression is what counts. |
