However, my other host (the 630) has now finished two tasks with the new settings and it's a major improvement in the run time. I hope the 440 ends up showing the same improvement. Well, looking at it while more awake, it's a major improvement in CPU time, but not total run time. Still, minimal CPU use is important to me on that box.

My first task reported since I added the switches came back with an error. It happened again, without the other app tying up the GPU. I have killed the .txt file and restarted Boinc Manager. If it happens a third time, I'll try restarting the computer. David Sitting on my butt while others boldly go, Waiting for a message from a small furry creature from Alpha Centauri. |

My first task reported since I added the switches came back with an error. I'm not sure how, but the dozen other GPU AP7s I had all timed out early, only four or five days old. I don't know if this was done by Boinc Manager, the server, or maybe it's a result of me disabling the txt file with the switches in it. Anyway, right now I only have AP7s assigned to my CPU.

... or maybe it's a result of me disabling the txt file with the switches in it. How do you "disable the txt file"? Do you delete the file (WRONG) or do you delete the contents (OK) so the file is empty? Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

... or maybe it's a result of me disabling the txt file with the switches in it. You can't change the file name or delete the file. BOINC treats the .txt files much the same as the .exe or .dll files. If one is missing it dumps all of the work assigned to that app. Also I have found it removes the other files associated with in the <app> section of the app_info.xml as well.

... or maybe it's a result of me disabling the txt file with the switches in it. I just had that happen to me earlier this evening. I wanted to test Raistmer's r2742 beta AP app containing the "zombie" tasks fix, so I copied the files and updated the app_info.xml. Since I was also planning to try out the new per-GPU config file, I thought I was being smart to add "AstroPulse_NV_config.xml" entries to app_info (which Raistmer had pointed out in another thread was a requirement). Unfortunately, I hadn't actually created that file yet before I restarted BOINC. Yep, the only 2 APs that I had in the queue got immediately dumped because that file was missing. When I checked the S@H folder, I discovered the r2742 .exe had vanished, too! Fortunately, both AP tasks were returned as "lost" ones once I fixed the problem and I was able to go ahead with my original plan. |

... or maybe it's a result of me disabling the txt file with the switches in it. Sigh. Okay. While I'm at it, should I upgrade to .43a, or doesn't it offer any benefit for my hardware?

... or maybe it's a result of me disabling the txt file with the switches in it. v0.43a contains the latest AP v7 released GPU apps. So it couldn't hurt to use them. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Argh. I may have another problem, but I'm not sure. I downloaded .43a and installed it. Going from memory and what files were in the project folder, I chose the SSE2 apps on the first page of the installer. Then I edited app_info.xml to change all the counts to .5. Then I started Boinc again. Here's the event log: 11/6/2014 5:44:38 PM | | Starting BOINC client version 7.2.42 for windows_x86_64 The lines I made red appear red in the log. That's what's worrying me. It's currently running three MBs on the CPU, and they were all running before the reinstall. (It's also running four Einsteins on the CPU and two on the GPU.)

Seems to be: Argh. Yup, looks like a problem - in which case, it'll be in the original 0.43 release too, I didn't change the CPU apps for the 'a' revision. Too late to work on it tonight - I'll look again first thing in the morning. |

11/6/2014 5:44:38 PM | | Processor: 8 GenuineIntel Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz [Family 6 Model 42 Stepping 7] But why do you choose SSE2 for this CPU - it have SSE3 (= pni) (else how do you think it may have the next SSSE3 ?)

11/6/2014 5:44:38 PM | | Processor: 8 GenuineIntel Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz [Family 6 Model 42 Stepping 7] I need to check who chose SSE2 - was that David, or the installer's CPU detection? (which shouldn't be confused by the PNI report - it doesn't use BOINC's detection string). My i5 (gen 2) pre-selects SSE4.2 - I'd expect the same for an i7 (unless it has AVX). Another one for the morning. |

From his post: "I chose the SSE2 apps on the first page of the installer" My i5 (gen 2) pre-selects SSE4.2 - I'd expect the same for an i7 (unless it has AVX) He talks about AstroPulse (for which I think only SSE2 and SSE3 variants are in the installer) (but he maybe also "chose the SSE2 apps" for MultiBeam?)

I need to check who chose SSE2 - was that David, or the installer's CPU detection? I chose SSE2 for both because, as far as I could tell, that was what I chose before. If it's wrong, I'll go back and do SSE3. How do I know what I should use? David Sitting on my butt while others boldly go, Waiting for a message from a small furry creature from Alpha Centauri. |

I need to check who chose SSE2 - was that David, or the installer's CPU detection? The installer would've had the correct version already selected for that app before you changed it. ;-) Cheers. |
