You video card users are making me jelous. All I have is on board graphics with 512MB shared memory. A AstroPulse puts a heavy system lag time on this number cruncher machine. Just glad it only takes 30 hours (approx.) to do one. Some system tweaking or drivers newer than Cat 10.4 might help resolve some of the lag issues. Then again it could just be a limitation of the built in graphics of that system. I am using the built in Intel Graphics on this machine. Which takes about a day to do an AP, but it doesn't seem to lag it. For about $75 it is a great little machine. Also as far as crunching with old out of data bits you may like to see this machine. It runs 24/7 and is sporting a RAC of about 60. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

I have a GTX 750 Ti but I don't know ho to install it on this Linux box with SuSE Linux 13.1. I have downloaded a driver from nVidia and have all instruction to install it, but if I install the driver when do I switch the monitor cable from the main board to the GTX?. I mean, before or after shuttding down and restarting? I have no experience with graphic boards. I found a Radeon 8670D installed on a new HP PC with Windows 8.1 and I was thinking of installing the 750 on it. but it needs a 400 W power supply (which I have on this box) but the HP has only 300 W. Of course the 750 comes with a self installing CD for Windows and Mac, none for Linux, as usual. Tullio |

Intel machine. My old computer was a AMD. Before the motherboard died of old age. I had a AMD Athlon II 2200+ cpu 1790MHz, 2GB max of ram and XP Professional Service Pack 3. |

The desktop is an old XP Pro build I put together at least 8 yrs ago It was 'obsolete' way before I built it but fitted budget and was a vast improvement over the 700Mhz box I had before. The MSI mobo was a good choice though as it has been upgradeable. Running Linux distro seems to have sped things up over XP (maybe just my perception?) Ivan, thanks for the info I'll try it tomorrow, laptop set here and desktop being played with, my short term memory is too bad to try and remember even a single line (that's another story of work accidents :( ) I've already done a,b,c you suggest but step 'd' on is 'new' |

Turn everything off before doing any work You'll probably have to disable on-board graphics in BIOS and set to NVidia card I just turn everything off but leave plugged in so ground lead to computer chassis is still connected. |

 I don't know Linux but obviously you don't understand which part of the line is command and which comment He uses -- as 'part of speech', Not part of command Probably this: sudo service stop mdm; sudo pkill -9 X -- ... will work if used as: sudo service stop mdm sudo pkill -9 X This looks absolutely strange: cd Desktop NVIDIA-Linux-x86-340.32.run Do you have directory with name NVIDIA-Linux-x86-340.32.run ?? (everybody knows cd means ChangeDirectory (in DOS, in CMD on Windows, ...)) Maybe: cd Desktop sudo chmod +x NVIDIA*   - ALF - "Find out what you don't do well ..... then don't do it!" :)  |

Well, I thought it was obvious I don't understand LINUX, I didn't understand Windows either. I'm a motorcycle mechanic not a programmer or something equally esoteric. I don't use computers every day, have no idea what a macro is, I expect to press buttons and have things work. Assembling hardware is dead easy, making it work is dead easy, making software work when you have to run various scripts and commands, is worse than trying to learn hieroglyphics. I figured out I needed to cd to Desktop then the NVIDIA section separately, learning by trial and error is real slow and difficult I'm not a complete idiot, but, I'm working on it. I have an opinion and I'm not afraid to use it |

Actually, he was almost there. The problem was; pj@pj-MS-7514:~/Desktop > sudo ./NVIDIA-Linux-x86-340.32.run -- Verifying archive integrity...

I'm copy/pasting someone else's instructions, I cannot remember syntax rules although I probably will learn them eventually (short term memory problem due to work accident in 2006) I'm not a complete idiot, but, I'm working on it. I have an opinion and I'm not afraid to use it |

OK That means the installer was working, but, it stopped when no option followed the -- You're almost there. I just placed my 8800GT back in a machine to test the latest AstroPulse build, http://setiweb.ssl.berkeley.edu/beta/results.php?hostid=72229 I bought my 8800GT new back in early 2008, I think it was $240. It's still going... |

Thanks TBar, that is much more helpful than some of the comments. I'll try the desktop again tomorrow I'm not a complete idiot, but, I'm working on it. I have an opinion and I'm not afraid to use it |

BTW, Problems have been identified with the New AstroPulse_v7 and nVidia driver 340.xx on the Older cards: "The outcome of this is legacy GPUs (at a minimum) should avoid 340.52 drivers." I have no idea if the problem exists in Linux, but, why take the chance? Really, there is no reason to install the latest driver for an 8800. You might want to download 331.xx or something similar, http://www.geforce.com/drivers/results/76749 Isn't NVIDIA-Linux-x86-340.32.run a 32 bit driver? It looks like you have 64 bit Linux. So, there should be a 64 in there as in NVIDIA-Linux-x86_64-331.89.run |

It's not just AP7, it's AP6 too, and not just the latest revision, r1843 (the app that was in the 0.41 installer) is affected too. Claggy |

Wish I had the opportunity to harvest my old dead computers video card. It uses AGP tech. LOL. |

Wish I had the opportunity to harvest my old dead computers video card. It uses AGP tech. LOL. There are some AGP cards that can be used for crunching. As far as I remember only ATI HD2xxx or later generation cards. Most of those cards could only do Astropulse work with the "hybrid" app. Which I think was said is no longer being developed. So forthcoming AP v7 will not be able to run on them. There are a few HD4xxx AGP cards that I think can use OpenCL, but the CPU has to support the right level SSE IIRC.

I see... It is a ATI Radeon Saphire something, but not HD. Ah regrets that my new rig has no slots to even try the idea. |

I still have an AGP HD 4670 that I used in S@h for a while. It only has a work-group size of 128 so it couldn't run Multi-Beam tasks. It would run AstroPulse in around 7-8 hours (remember this was well before GCN), one at a time. Towards the end, it also produced quite a few invalid results (other cards on the system were fine), so I gave up on it. As I understood it, AMD OpenCL support on HD 4000 series was 'beta' only. Also, it was running on WinXP, which I feel wasn't as well supported at the driver level as Vista and Win7 (had some issues with HD 6900 series which were no longer present after moving to Win7). It was an interesting experiment while it ran, but eventually I retired the AGP system altogether. Soli Deo Gloria |

ERROR: You appear to be running an X server; please exit X before It is very probable that X means X server: sudo service stop mdm sudo pkill -9 X (I don't know what is mdm, probably: http://community.linuxmint.com/software/view/mdm) (I don't know what is -9 but pkill have to mean ProcessKill) Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |
