OK I know next to nothing about it, but shouldn't my new notebook use AVX with the new AP app? Seems it didn't or I'm not reading it correctly ;) http://setiathome.berkeley.edu/result.php?resultid=2371596165 |

OK I know next to nothing about it, but shouldn't my new notebook use AVX with the new AP app? It is the fftw libary that uses AVX, not the app itself, Edit: if you copy wisdom.dat from your project folder to the desktop, and open it with notepad, you'll see what codelets were used. Claggy |

OK I know next to nothing about it, but shouldn't my new notebook use AVX with the new AP app? You'll have to ask Jason how AVX usage is flagged in the task output. You meet all the criteria we know about - running the r557 app, second-generation i7, Windows 7 with SP1. But as we said a couple of days ago, we just run the delivery service: we're not responsible for the contents, I'm afraid. |

Yes wondered about that file, and it does contain some AVX stuff. |

OK I know next to nothing about it, but shouldn't my new notebook use AVX with the new AP app? AP 6.01 was a fairly hasty release all around to ensure the project's sudden move to introduce changes was covered. Rush releases like that aren't typically friendly to cosmetic issues ;) With hard wired feature prints derived straight from r409, it doesn't indicate AVX anywhere there. I'm in the process of further optimisation & changing those features lists to 'true' detections for future CPU based dispatch, so won't likely stay like that long. For now, if in doubt that AVX is enabled internally, just go by runtimes as compared to older r409 builds with v505 in comparison. Typical AVX enabled rutnime is about 20-25% faster than non-AVX, so it should be noticeable. Jason "Living by the wisdom of computer science doesn't sound so bad after all.

The Stock apps also generate wisdom files, and so did AP r409, but they are generated in the slot directory every time a Wu starts initially, now the wisdom.dat file is generated in the project directory once, and the app refers to that copy and updates it as needed, Claggy |

The pc is now running x41u_cuda32, 1 task at a time. When all 4 cores are used, there are dropouts where the GPU load is close to 0 for about 20-30 seconds. The progress bar in Boinc is then still moving, but only at around 0.001% per second. With 1 core free, the GPU load slightly increases, but there are no more dropouts. I checked both the Linux pc's running x41g for the difference when 1 thread or core is left free: Q9650 + GTX260 running Seti Cuda and 2xSeti AK_v8 + 1xLHC T4T on the CPU: "Top" shows a 6-8% cpu utilization from x41g With 3x Seti and 1 x LHC T4T, the cpu load drops to 3-6% and Cuda tasks run at around half the speed i7-920 + GTX570 448 running Seti Cuda (3 tasks) and 6xWCG + 1xLHC T4T on the CPU "Top" shows a 4-9% cpu load for each of the three instances of x41g There is no difference whith 7x WCG + 1xLHC T4T but the WCG application may not be as demanding as the Seti AK_v8. Tomorrow I will try the same with 7xAK_v8 [edit] the first tasks on the i7 at "full load" took about 15% longer than with one thread free. The difference is smaller then with the Q9650 but there is a difference. |

Victor is also reporting issues, & has giving up testing in a snot. Right now I have no idea what's causing either of your issues. Will look at some of your results...

Having been rude to me by PM, you'll not get any more help from me ever, and I'm putting you on ignorr. Best of luck with your problems then.

Victor is also reporting issues, & has giving up testing in a snot. Thanks a lot, I wasn't trying to be rude to You Jason. Here's x41u, It isn't any better than x41g, but like I said I wasn't, I'm sorry if I came across that way. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Figured it out I think/Hope Some time back, ~x38g, I had detected many programs including OpenCL & CPU apps throttling the Cuda programs which was killing the threads, so I raised the app prioties to normal so they'd stay alive. Unfortunately, in doing so, I was bombarded by demands to put it back to below normal, which I did for x41 series. Please try to use something like either Fred'd efMer prioroty tool, or Process Lasso to jack up the Cuda process priorities. I'll consider making the default priorities configurable in the near future. Both x41g & x41u should operate normally when not being throttled by other programs running at higher priorities. This will slightly delay next release, but hopefully not too much Thanks for the help tracking this down. I'll think harder next time before reversing design decisions based on angry dudes comments.

The pc is now running 2 cuda tasks at a time and with 1 core free. I checked a number of stderr outputs but I could not find any difference. All tasks seem to validate fine so I'm not too worried. Could be worth adding a remark to the readme file about leaving 1 core free. Here's another Afterburner screenshot (1 task on x41u_cuda32): The first circle indicates where there was 1 core free. Then I added the fourth core and the dropouts begin. The circle on the right side indicates the loading of the next task. I have not yet found any correlation between the dropouts and any other occurence on the system but since the dropouts are 10 seconds or more this should be easy to find. |

Thanks, Can you jack up the cuda process priorities (with one of the tools mentioned) & compare ? BTW: for some reason I'm having trouble getting to your images.

It is a great joy to see this Astropulse application 555 whack these out in max 1 hour 45 minutes. I am very sorry for my rude behavior when the 40 installer was released and there was no Nvidia app for astropulse. Great job on all fronts. LadyL and Claggy thank you for the 555 app I am using Nvidia 266.58 x64 drivers Can I go up to cuda 4 or do I stay at 3.2 I saw that 270+ does work Just curious Michael Miles |

Will those work to fix this on the ATI client as well? I don't understand why half of my WUs run normally and half of them crap out. |

(Just jumping in to say I can see the images fine) Probably my end then ;), My internet's doing freaky things tonight with all sorts of things... oh well, that I can look into later.
