I'm gonna let this I7 go for a day then set up the I3 I'm gonna take that 34 computer dude out with 4 computers. Or die trying. Wawasoo. |

Both my I7 & I3 are Cosair liquid cooled...and the I3 sever has a gazzion fanz...in the box. If you don't have that, don't do this...cause I'm screaming. |

First of all,make a new folder somewhere on your hard drive where you can easily find it,and call it something like lunatics 0.40 app info files Now locate your app info file in your BOINC folder. In windows 7 it will be hidden. You need to select show hidden files on your computer. Then it should be something like My computer/ drive c/ program data/ BOINC / projects/ SETI@HOME/ Scroll down past your work unit files till you come across one called app_info . Right click on this and copy it. Leave it alone for a while. Find your new folder you made earlier and paste the copy of your app_info into it. Paste it into your new folder 3 more times.They should automatically be called app_info copy 1 etc. Right click on app_info copy 1 and choose "open with notebook" or " edit" Scroll down to the bottom of the page. Slowly scroll back up until you see <COUNT> 1 <COUNT> Replace the 1 with 0.5 Slowly scroll up and repeat this procedure every time you see the <COUNT> 1 <COUNT> line. Now select FILE --- Save as,and select "all" file types. It should now be saved in your new folder as app_info copy 1 as an XML file (not a text file). Rename this file app_info X2. Now go to app_info copy2. Repeat the procedure above but use 0.3 to replace the 1. Rename this file app_info X3 Goto copy 3 and repeat the procedure with 0.25 to replace the 1. Rename this file app_info X4 You now have 4 app_info files in your new folder(out of harms way) The original file will do 1 WU per GPU. The X2 ,X3 and X4 files will do 2,3&4 WUs per GPU. Stop all WUs that you are currently running. Now copy one of these files ( I'd recommend X2 for the time being) and paste it into your BOINC folder where you found the original app_info file. It should appear next to the original file. Delete the file called app_info ( don't worry, you have a copy of it in your new folder). Rename the file "app_ info X2"by knocking the X2 bit off the end of it. Resume your WUs ,and you should be doing 2 at a time. Remember to leave your original file in your new folder alone,if things go T U you can always replace it in your original BOINC folder. john3760 edit Sorry it took me so long to write this ,that you have already done it !!!!! |

This thing is going through the roof. It's banging 3 Cudi Fermi Task a Minute. Don't get to excited. Right now you are chewing up shorties, or VHAR tasks. VHAR=Very High Angle Range. Which you can see in the task result by looking at the number WU true angle range is :. In the case of that task it is 2.733399. Where a "normal" task would be around 0.42. This thread has a good explanation of where the angle ranges fit in which group. The easy thing to remember is VLAR=slower(lower number), VHAR=faster(higher number).

Way to go Wawasoo, glad you got it going. One other thing that should be mentioned is the number of errors you are showing. Don't panic, they are VLARs that were sent to your GPU by mistake as resends. Since Nvidea GPUs don't handle VLARs very well it assigns them a very short due date so they time out quickly and sends them back in to be done over. PROUD MEMBER OF Team Starfire World BOINC |

The errors on his GT 240 aren't VLAR errors. They seem to be 295 driver errors,as the GPU cannot be detected ( asleep perhaps? ). The couple of GPU tasks that have completed have deferred to the CPU,hence the longer run times. @ wawasoo. You need to roll back the driver on this card,or disable the computer from sleeping. 285.66 drivers will work.Also when you sort out the problem,I would only run 1 WU on that card for a while till you get it running smoothly. At a later date try 2 WUs ,but 3 will probably be a bit too much for that card. I'm sure somebody else will be able to pin the problem down a bit more precisely than me and give you better advice,but I would definitely get rid of the 295 driver on that card. Good luck on the taking down of 34 computer dude ;) p.s You won't do it erroring out WUs . p.p.s The -12 errors on your 560,can't be helped,don't worry about those. john3760 Edit : It looks like he has woke his 240 up. WUs are starting to pend and validate. |

I was having problems with the newer drivers for my NVIDIA cards and had to roll them back. That worked for all but one system. I then went to the NVIDIA site and found the BETA drivers, 301 series and installed them and they are working great on my systems. I was having all the noted problems, in various forms, now all is well in GPU land. I do have to say the one system crashed during the install, but when I rebooted it the drivers had been installed.

The errors on his GT 240 aren't VLAR errors. Yea it started throwing off erros on the screen saver I woke up and saw all the cuda apps had errored out. I think I got it now. I call that Pending file under Tasks, My Bank Account for future credit. The GT 240 had been keeping about 10, it's getting closer to 20 now after running correctly for 10 hours. The I7 has increased it's account from around 300 to 460 after running 20 hours. Gonna be some big time points down the road on this machine. The little AMD too was erroring out, but I think that one is now on the straight and narrow. That one took on average 19hours to complete a task which one core in my I7 could do in an hour. Got the first task out of that one in 2.5 hours, like 17 hours in processing increase. Fingers crossed that it can handle an AstroPulse on it's slim GPU. And it's got a bank account of 1, which is a record for it. Now the I3 Server is next, it's bank of pending tasks has hovered at about 150, If I put the juice to that one I sould be well on my way north of 220 by tomorrow nite. But before I do I want to roll back that bad driver. What's the best way to roll it back? |

The I7 Bank Account it approaching 500 now. Man did I have trouble with the I3 Server. It's a 64bit machine running WHS V1 which is 32bit. Blew up everything when i put the wrong Lunatic software on it. 64bit, Don't work. But, I'm not switching to WHS 2011. I like my JOBD WHS V1 software, it's Idiot proof Server Software for the Home Computer Idoit.....and I'm living proof. It's racking up nears 200 in it's Pending Bank account, about a third in 5 hours...even with me putting on the wrong software, it'll be over 220 Pending by the time I wake up. I'm not sure I've got the right CPU version running yet....still may need to do some more research. That little AMD 1 processor has put up 2 tasks in the last few hours; 8. It use to do 2 every 3 days...so it's working. But if I can get this I7 up near 40,000 a day I'll build another one and lay that 35 computer dude in the Dust. Any thoughts or Ideas would be appreciated. I've got a few old Cabinets, a brand new gts 450 sitting on the shelf, not fast enough for games...maybe I'll SLI up a beast from Tiger Direct parts. Any thoughts on that too would be appreciated. RAC Numbers still Climbing....by the hour. This Post 17,234. Wawasoo. |

It's a 64bit machine running WHS V1 which is 32bit. Blew up everything when i put the wrong Lunatic software on it. If you're running a 32bit OS, then you can only run 32bit software. If it's a 64bit OS then you can run 64bit software. RAC Numbers still Climbing....by the hour. This Post 17,234. Generally it takes 6-8 weeks for RAC to stabilise when you make major changes- ie a new machine, or add a GPU to a machine. Going from the stock application to an optimised one it took about 4-6 weeks for the RAC to stabilise. Of course server downtime & hiccups can easily add several (or more) weeks to that.

Go to the nvidia website ,legacy drivers page. find the driver you need .do a clean install. Or just don't let your computers sleep.,and switch off all screensavers. john3760 |

Hi, This is the guy I want to hear from, one I7 doing 41,000 RAC. Whatever he's running I want 2. And I'll take that guy out with 2 machines. Please give me a step by step. http://setiathome.berkeley.edu/show_user.php?userid=185350 |

If you run more than 1 video card in your computer don't use SLI if you wan't to use them for crunching SETI. Keeping the two cards separate allows BOINC to detect 2 GPUs( the processing bits inside your graphics card). john3760 p.s @ Wawasoo. You may want to start your own thread within Number Crunching, as you are at the bottom of someone else's very long thread.I'm sure you will get more help from very knowledgable people on the SETI message boards if you do so. |
