Post: Hmm USB 5.25 eh.... Would love to archive my C64 stuff onto PC somehow. Yes I've got an emulator but it's my own stuff on the disks I would like to live for eternity. I still have the first 2 years of Byte magazine sitting in storage. And they are stacked high on shelves, well above any water line... |

Post:
We are a society of people, who live on the earth together. None of us are perfect, but too often, we stop thinking beyond ourselves too much. I agree that how we treat others around us is a reflection of our society. I disagree that we should hand over the duty of taking care of "the weakest" to government. In the end, it's the responsibility of us all to take care of others. And I'm tired of blaming "the evil corporate entities" as the problem. They are part of the problem. But it's also a problem of believing that folks that take responsibility for themselves, build a business or trade, and then are taxed at a high rate BECAUSE THEY ARE SUCCESSFUL should pay for anyone who "can't afford healthcare". I'm willing to pay my share, but that share shouldn't be any more than anyone else, including the "middle class". So put a 1% (or whatever percentage fits here) tax on everyone's income (including Congress!) to pay for a better way in healthcare. Note: I'm not in the healthcare industry, but have been dealing with it for over 40 years. I don't make over $200,000 or whatever number is considered "rich" these days. I'm tired of the politicians trying to spend the $ I send to the government... |

Why only 3 CPU's with Core 2 Quad CPU?
(Message 915815)
Posted 8 Jul 2009 by computerguy09
Post: Hal had it right. When the project sent out the GPU based WU, it estimated that it would use about 10% of a CPU to help run that WU. For the "normal" CPU based workunits, probably coming from a project like SETI, they each will use 100% of a CPU or core. So when you see 5 WU's running, you should be running 4 CPU based WUs, and 1 GPU/CUDA based WU. Based on that slight overhead in the CUDA WU, I typically do run my Q6600 @ 80% multiprocessor utilization. This allows my box to run 3 CPU-based WU and 1 GPU based WU, and leaves some time for the real user of the box (me!) to do things on the screen as well. To fully cover every possibility, be aware that some BOINC projects, like AQUA@home, now have a multi-threaded application, which can use multiple CPUs for one WU. So those will show up as (3 CPU's, 0 CUDA), and so you'll see only 2 or 3 WU running on a quad processor machine. Mark |

Posted 8 Jul 2009 by computerguy09
Post: Thank you Hal. You have a video/graphic card in your PC that is capable of running CUDA tasks, which run on the GPU in your video card, not on your CPU. So it's taking up part of one CPU (.11 or about 10%) and all of the GPU to run a work unit (WU). This is normal for a CUDA WU from the GPUGRID project. As mentioned earlier, be sure your CPU and Multiprocessor preferences are set to 100%, and you should be running 4 CPU based (normal) WU and 1 CUDA WU on your C2Q. Mark |

Post: I do recall one PDP system we had that suddenly started to re-boot itself when no-one was around. After much headscratching, this was tracked down to the latest batch of fan-fold paper on the line-printer being wood-free and building up an excessive static charge; eventually it would throw a spark to the nearest earthed metal and... Sounds like an RP06. Ah, those were the days... |

I don't get any CUDA Apps :-/
(Message 856278)
Posted 22 Jan 2009 by computerguy09
Post: 01/21/09 19:33:21|SETI@home Beta Test|Message from server: Can't use CUDA app for SETI@home Enhanced: Your CUDA device has the wrong software version I believe it depends on which CUDA version you compile the app with. Current version of CUDA is 2.0 (I think). For those v2.0 apps, there's backward compatibility to CUDA 1.1, but not to 1.0. At least that's the way it's been explained in the GPUGRID forums. It also may be that the old v1.0 cards can still crunch, but since they take so long to complete, it may not be reasonable to run them. If, on the other hand, there's no technical reason not to run the old V1.0 cards, and SETI's deadlines are long enough, then more power to remove the server side restriction. |

Post: Thank you for the feedback! 8800 GTS 320/640 is the "old" G80 GPU, which typically won't run with CUDA v2 apps. It certainly isn't supported on GPUgrid, and probably isn't on SETI. While CUDA drivers will load on this card, any recently built CUDA app most likely will run very slowly or not at all... |

What will my experience be with CUDA?
(Message 855799)
Posted 20 Jan 2009 by computerguy09
Post:
Is this a Laptop/Notebook? IF so, then you risk overheating. Notebooks weren't designed to run GPU at full tilt for 100% of time. In the message log, what is the full line that shows CUDA device detection. Hopefully it doesn't say "emulation" anywhere. Just trying to verify that your graphics card is supported. If you've setup BOINC to use the AK version, then you've got an app_info.xml in your SETI directory. You'll need to change/customize it to allow CUDA apps to be downloaded/run. That's not a trivial task, and is most likely the reason you're not running any CUDA WUs. |

Posted 31 Dec 2008 by computerguy09
Post: Hi Guys Here's some free advice. If the projects set the % of CPU required for the GPU application to the right value, BOINC *should* manage the number of WU's of the correct type for you. By this, I mean that you shouldn't have to set NCPU's in the config file to anything higher than the actual number of CPUs/cores. I have seen 5 WU's running on my quad with a single GPU card. However, for some projects (GPUGRID, for example), the amount of CPU required to keep the GPU app fed takes 60% of a core, and so trying to run a CPU WU with a GPU WU isn't worth it. This only occurs on Windows - the Linux apps take only about 10-20% of a core to keep the GPUGRID app fed. So, my advice is to stay away from the config XML file, and run more than one project so that you can easily keep all GPU and CPU cores running. |

BOINC not pulling 6.05
(Message 842014)
Posted 19 Dec 2008 by computerguy09
Post: If you have an app_info.xml file, it won't pull the CUDA client. Also, I'm not sure that the "custom" BOINC client 6.5.x supports, or knows about CUDA. (At least one poster here showed 6.5.x in their logs) BOINC client 6.3.x to 6.4.5 knows about CUDA, and will use the CUDA DLL to detect if there is a supported GPU present. SO the first thing to try on a new setup is to install BOINC 6.4.5 client, then attach to SETI. That should pull the standard SET CUDA client. Now, if you want to try to switch to BOINC 6.5, OK. If it works, great, but no guarantees. That would be my approach. Also note: Not all 8600/8800 video cards are supported by the SETI CUDA client. Got to the nVidia website and see if your card and GPU support at least CUDA v1.1 (NOT 1.0). And the latest nVidia drivers with CUDA 2.0 support are required as well. |

Does anyone run CPU + GPU SETI on main?
(Message 842010)
Posted 19 Dec 2008 by computerguy09
Post: i think if you install boinc 6.2 and 6.4 in two folders then run them both ... I was going to suggest just the same thing. I'm currently running 2 VM's on my quad-core Q6600. The box runs Vista 32-bit, but the 2 VM's are running 64-bit Linux. While I'm running the same project (Primegrid challenge right now) on all 3 "boxes", I could just as easily run the GPU SETI client on the "host" box, and be running AP units in the VM's. Host client is set to only run 1 processor, and the other 3 are split between the VM's. Works fine here. Note: the ability to run 64-bit VM's with VMware under a 32-bit OS is dependent on your CPU and BIOS. VMware has a utility on their website that allows you to check this... VMware player is free. |

Post: Matt, Thanks for all your hard work. Thanks also for the acknowledgment that Beta uploads are hosed. I did some GPU work on Beta and it's been sitting on those uploads for forever (or at least since Tuesday!) I had already rebooted the box (thank you, MS, for still requiring reboots after some "updates"), and since it's running 2 VM's with lots of PrimeGrid work, has no problem uploading to other projects... |

Multiprocessor question
(Message 840306)
Posted 15 Dec 2008 by computerguy09
Post: As per the SETI preferences page, Just so it's clear, there are two different settings: A: Use % of # of processors B: Use % of CPU time For Multicore/multiprocessor machines, if you see a slowdown, it's recommended to set A to less than 100%. That frees up a core to allow other things to run. If you set B to less than 100%, you are telling BOINC to pause frequently on EVERY core to get an average CPU utilization of say, 75%. So, you'll run as many WU's as you have cores, but at less than full speed. As an example, I was seeing heat/shutdown problems with my laptop, which has a dual-core AMD processor. It works much better, and with less stress on the fan/CPU to set A to 50%, so it only runs one WU at a time, on one of the cores. I did try to just set B to 80%. It did run 2 WU's but it didn't seem to run as well. |

Qad core will not reboot
(Message 813051)
Posted 29 Sep 2008 by computerguy09
Post: Easiest method to test, grab a DMM, turn on PC and remove the mobo powersupply.. check your PSU PIN out schematic and confirm the required voltage output, since its all TTL.. set the DMM to the appropiate scale of measurement. A quick note on this technique. The PS won't put out the listed voltages unless the "PS_ON" pin connector is grounded. This is usually used by the power switch circuitry to control your power to the CPU etc... A good way to check if all the required signals are correct is to monitor the PS_OK pin connector. This signal is raised when the PS says all the voltages are correct. So you can't just disconnect the cable from the motherboard, turn on the PS, and expect to get voltage on each pin. |

WOW...GPUGRID!
(Message 811881)
Posted 25 Sep 2008 by computerguy09
Post: Hi PaulDHarris, If you get this message "Device Emulation", this usually means you don't have the right driver loaded, or that your card isn't supported by the latest CUDA driver. PS3GRID (and Nvidia) recently moved to using CUDA version 2, and some older cards (including some of the 8800 series!) only support CUDA v1 and aren't supported to run PS3/GPUGRID. I'd check the forums at PS3GRID. They have a sticky post that highlights which cards don't/might/will work. |

6.2.18 Issues.
(Message 811875)
Posted 25 Sep 2008 by computerguy09
Post: I see that BOINC 6.2.19 is out. Fred, Not sure what's wrong with your setups, but I've been running 6.2.18 on 3 or 4 rigs (WinXP and Vista) for awhile without any problems. I've slowly been converting my 5.10.45 rigs to the 6.2.18/19 version. I will leave at least one at 5.10.45 (it's an old P3) that runs LHC and a few other projects because of LHC's problems right now with 6.x. I did try to run my quad 6600 on 6.3.10 for a little while, for GPUGRID, but due to problems with BOINCview and the graphics drivers, I moved back to 6.2.18. |

Post: Only 900 pending? When I checked this morning before going to work it was up around 1100. Cosmic, That's not 900 credits pending, that's 900 work units in cache. A big difference. I try to keep about 1 day's worth of WU in cache, which isn't much, but then again...I run several different projects. |
