For some strange reason libfftw3f-3-3_upx.dll keeps getting deleted in all my rigs. Three of them are running AVG while my main rig has Bitdefender. I have put up an exclusion for this as well as the v7 main executable files, although neither gave any warnings. I thought the warnings were only for the exe file. All the completed v7 WUs are now piling under validation pending. ______________ ![]() ![]() |

Now that my GTX460 cruncher is on stock app for the first time, it downloaded its first Nvidea AP to crunch using opencl. However, GPU utilization is very low. For MB WUs, GPU utilization is typically 80-90% (for 1 v7 WU), but the AP was only showing ca 4% GPU utilization. I freed up one CPU core and this increased to 18% with occaisional bursts up to 100%. Freeing up a second CPU core made no difference. Is this normal? Yes, you need to free a CPU core for astropulses. You can speed things up. Add the following params to your ap_cmdline.txt -unroll 10 -ffa_block 6144 -ffa_block_fetch 1536. With each crime and every kindness we birth our future. |

There doesn't seem to any stock linux app for nvidia, will there be an opti app on Monday? Will Lunatics_x41g_linux64_cuda32 work with v7? |

Is there a clever way of freeing up one CPU core when the GPU is running an AP but when it is running MBs which do not need it? I do not want to loose 25% of my CPU RAC and cannot lways be present to baby sit the machine.With your version of BOINC, you can do this with an app_config.xml file in your SETI data directory. Here's mine - set the gpu usage value to the values you need for your card. You don't need the max concurrent line - I use it to limit the number of AP's running at one time. Setting a value of one for the cpu usage will reserve one core but only while the AP task is running. <app_config> <app> <name>astropulse_v6</name> <max_concurrent>2</max_concurrent> <gpu_versions> <gpu_usage>.33</gpu_usage> <cpu_usage>1.0</cpu_usage> </gpu_versions> </app> <app> <name>setiathome_v7</name> <gpu_versions> <gpu_usage>.33</gpu_usage> <cpu_usage>.06</cpu_usage> </gpu_versions> </app> </app_config> Add the following params to your ap_cmdline.txt Mike, will r1316 accept those command line switches?

There doesn't seem to any stock linux app for nvidia, will there be an opti app on Monday? Frankly we haven't the faintest idea. It has AC code but it's not been alphaed on Linux. update your app_info with the tags that have been published and give it a try? Pay close attention to any problems. x41g is going to have a higher rate of inconclusives, but it may just work. A person who won't read has no advantage over one who can't read. (Mark Twain) |

Well, things seem to have settled a bit here. My RAC drop is not so declined as before. I have all the kibble I could wish for under the still enforced 100 task bit. I suppose the drop in RAC is due to the fact that pendings are up a bit, and I am waiting for the new opti installer to do more than one task per GPU. I have checked a couple of rigs, and it looks like I am at 90+ on all, so the few percent I am not using on a few rigs might account for something.

One WU finished waiting for validation. Much appreciated here :) Dr Ivan mentioned, buried amidst the chaos, that he's going to have a look for x41zc update needs, and Urs provided some helpful starting suggextions.

More than half the time was spent in class T_remove_radar_randomize which has to be run on CPU. Joe |

The developers might want to look at the V7 rollout again with regard to the inability of the servers to supply the necessary files to run the tasks. I'm still pissed that upon updating to V7, the project promptly assigned me 100 CUDA50 tasks while the client was still unsuccessfully trying to download the .DLL for them. And all 100 tasks got errored out immediately because the DLL was still missing. It took over 2 hours to persuade BOINC to download the DLL file. I would have thought the system should not have downloaded any tasks until the necessary files were on board.

I would have thought the system should not have downloaded any tasks until the necessary files were on board. It downloads them, but then holds them untill the necessary files have downloaded. They wouldn't have errored out unless something else happened or was done (such as aborting the download of one or more of the application files). That's the way it was for me. Grant Darwin NT |

Maybe this is the correct thread to ask this question. The auto correlation increases the sensitivity for weak signals by how many db? |

I didn't abort the download. I kept hitting try again and watched the backoff times increase, so I shut client down and rebooted. Again watched the client unsuccessfully try to download the .DLL (either unable to access the server or server timeout). Got disgusted and left the room. Came back a couple of hours later and saw the client finally got the .DLL. Only, now the server is only offering up mainly CUDA32 tasks and a couple of CUDA42 tasks. My quota for CUDA50 is now 1 a day until the errors clear. Cheers, Keith Seti@Home classic workunits:20,676 CPU time:74,226 hours ![]() ![]() A proud member of the OFA (Old Farts Association) |

Came back a couple of hours later and saw the client finally got the .DLL. Only thing that comes to mind is in it's many attempts to download, one of the files was corrupted or only partial. When it tried to run, it errored out the WUs & re-downloaded the file. I had something similar happen on one of my systems; on the other system i just left it alone & the files eventually download OK & things started running without aborts or other issues.

Maybe this is the correct thread to ask this question. The auto correlation increases the sensitivity for weak signals by how many db? None. Autocorrelation is a search for a different type of signal, where the transmission is the combination of an original signal combined with a delayed copy of the same signal. Such a combination would be a good indication of intelligent intent given a significant delay. Joe |

After 2 days of work, still having some trouble with the scheduler dsending the wrong WU to some hosts, for example cuda50 to a 590/580 host, cuda32 to a 2x690 host, etc. Any clues how to fix that? ![]() |

I'm stuck in the same boat. My two computers, both with 670's, started on 100+ tasks using 32 on one and 42 on the other. Neither computer has any 50's validated so the server cannot make a decision yet on which is the best app. Although one has got 32 and 42 tasks validated and it should see that the 42 app is much better than 32. When I get 50's tasks I force the computer to do these asap, in the hope that the more done the greater the chance one, at least, will be verified. |

The wierd thing is i allready have a lot of cuda42 work done in the 590/580 host and the scheduler continues to send only cuda50 to that host, the same happens on the 2x690, it allready have a lot of cuda50 done and the server still sending cuda32 to it. Something similar happening of some of my others hosts. I just don´t understand why not put a instruction to allow us to choose the best app to our host manualy, that could save a lot of time and resources. ![]() |
