Ah - I was afraid of that - I can't register. They don't sent a validation email and I sent them an email to that effect but have yet to recieve a response. | |

This post has the updated exe CUDA app with the rest of the files needed in a zip file. I had the same problem with lunatics and had to go thru my spam filter to find their message to me. | |

Ok i went to geocites and got the file - I detached seti and then reattached halting all downloads. I stopped BOINC. I placed the downloaded files in the Seti directory and restarted BOINC and the files all ran for 28 sec CPU time and finished. | |

just check your drivers. | |

All drivers are right on the money | |

All drivers are right on the money Sorry, I couldn't find it if you already stated it, but what drivers are you using now and what have you tried? There is available now for your card the new Beta 181.20 just recently released. As well as the older Beta 180.48 And of course the standard 178.24 for your card. I'd think the newer Beta drviers are the ones that might have the best results, but it seems to be differenet for each OS and pc. You might have to try a few to find the one that works the best. Looking at the results you're getting now, seems like a driver change is in order. I had the same problem using 180.48 but went to 180.60 on my card and made all the difference, so far haven't had a reason to go up to 181.20 ____________ | |

Hi Byron, | |
| ID: 851658 · | |
Hi Byron, I'm sure they were and are. The problem can be though not that the driver isn't installed correctly, but rather the CUDA app we have just doesn't like some of the drivers over others. You have a common problem on WU true angle range is : 2.716657 and similar AR which probably are false positive -9 overflows. You could use the method in this message to keep them off the server, and keep them from polluting the database with false results. You can also use a batch file to spot Very Low Angle Range, or VLAR tasks (0.1 and lower anggle ranges ) that you can find examples of in this thread. Most likely VLAR tasks will be a problem to run and can also have side effects, like snow on the monitor and reboots, etc. Also if you go back to the link you got the modified app file that I posted it's been updated to a newer version that may help with the overflows You'll need to monitor your pc for a while till you're more aware what kind of angle ranges it can and can't run ( CUDA still a bit buggy even with the right drivers) once you determined you have a driver that is somewhat stable with the CUDA app, and take the precautions needed to avoid any problem ARs, it should be fairly smooth. Out of the three drivers you've tried does this version seem the most stable to you? One other thing, since we are now dealing with the modified CUDA app, it's been requested that we use the forum Modified SETI MB CUDA + opt AP package for full GPU utilization when giving help for that app so that the stock app can be discussed in the CUDA section. Noticed one other thing on your card in the stderr. Not sure what it means but it seems to be different with most other people's cards I've looked at. major = 1 minor = 0 seems like in the other cards I've looked at the minor=1 too. That may have a bearing on some of the problems you're having and you can raise that question in the other forum. ____________ | |

Thanks Byron but I am getting lost and confused. Is it possible for you to give me a step by step procedure for proper installation of BOINC? | |

Thanks Byron but I am getting lost and confused. Is it possible for you to give me a step by step procedure for proper installation of BOINC? Why do you want to reinstall Boinc? The line in red shows you have CUDA. Just go back to the opti app and download the mod updated CUDA app and give it another try or continue to use the stock. In my opinion the mod app is easier on your system. If you need we can go over the steps in my last message and there are also others at the forum link I gave that may be able to explain it better than me. I'm proabably not the best communicator here. It is important to realize though that CUDA still is a Beta app, even the stock, so even under the best circumstances it still has problems and is difficult to run. ____________ | |

I did not reinstall BOINC - I just detached from seti and reattached. | |

seti is not taking any new tasks so I will abort the three seti tasks no in line on my computer and update seti to clear them.If you still have Seti tasks waiting to run you don't need to abort them. You can just install the app and process them. The Duration Correction Factor was reset when you detached and will take a while to increase, but will in time. You won't run out of work, but it may wait till you've completed all the tasks you have before assigning new work for a while. Then I will stop BOINC, extract all files from opti.zip and place them in the /projects/seti... folder - replacing the existing files. Yes Another thing, I have a 280 card on another machine running Vista. It is fine. The 8800 series has been know to have problems with Seti Cuda and compute campability. some have 1.1 others only 1.0. This could be part of the problem but the mod app has been known to help with this. Question is should I place the opti files in the vista machine too? It's more optimized than the stock app so it should be somewhat faster for that card too. It should also make it easeir for it to do the tasks too since that's what the code in it is designed to do. It's the same basic code as the stock with some tweaking. ____________ | |

Done and it added cuda the the application name. | |

Ok, So you're getting an overflow in angle range 0.378811. That seems to be a problem for the driver you have for the card. 0.4xxxx also seems to be a no go either as well as 2.7 when it comes to overflows. | |

It has always been the same... they either complete in a few minutes asking for .01 to .08 credits or run forever. The driver did not seem to make any difference. Should I have downloaded the v.20 cuda dribers from nvidia? | |

It has always been the same... they either complete in a few minutes asking for .01 to .08 credits or run forever. The driver did not seem to make any difference. Should I have downloaded the v.20 cuda dribers from nvidia? To be honest with you, you need to download any drivers from 178.24 to 181.xx and try them all. And then try them again. In most cases there's only one that works the best. There will still be overflows in AR 2.7 and some others, but down to like one or two every 10 successfull ones or so. You should reboot the pc once you have one of the 27 sec tasks (overflows), that has been known to clear it up at least for a while. Of course if you keep rebooting and it just keeps happening, then it's time to try another driver if there are any left. And most likely the VLAR tasks will either compute error, or stall and have to be aborted, or could even freeze or BSOD your pc (that's why we abort them) so you'll want to run the batch file I mentioned earlier to keep those out. Edit: I checked again on the nvidia site and the 181.20 are the drivers they recommend as the current CUDA driver for your 8800GTX I also just got some feed back on what I mentioned I had seen in the stderr of the tasks you were doing and it looks like you do have the 1.0 compute capability with that card. Seti works on 1.1 so there's a chance the card just isn't going to work with the app in it's current state. Question, what does Think revision version of CUDA (so called computational ability or smth like this - check correct spelling on nVidia site). In general 1.0 - 8800 cards. Lack of some very useful abilities. All with 1.1 and up have mostly stuff that needed fore real work. ____________ | |

Damn - what am I to do? | |

Damn - what am I to do? Pretty much what you're doing. Trying different drivers to see if one is more consistant than the other, and hopefully one that can run the tasks without resulting in just overflows I just installed 178_20 drivers - seti downloaded many wu's and completed 3 in 28 seconds - I then suspended seti but I sure could use some simple instructions. It is getting back into the confused state. It's really just a matter of wether you can find a driver that will run at this point. There have been others I've seen here with 1.0 that have gotten it to work, though I can't say they didn't end up having the same problem in the end. You will want to keep an eye on the different angle ranges that you will see in the stderr file, so you can see if there are any angle ranges that you are able to complete. It's not uncommon for there to be angle ranges that will create overflows and errors. It's only a problem when you can't do any AR's. I have no idea what the stdrr stands for. It has been a standard installation with the exception of the opti package I'm sorry, this is the stderr file. Each task has one and you can access them through the Tasks for host page by clicking on the Task ID. Before the task is completed there isn't much info, but after it's completed and back on the server you can access the task details from it. ____________ | |

cuda-z says my compute capability is 1.0 - does that mean I have to stop using cuda for seti? | |
