Uh, oh... And....my bad, folks. I just recovered my daily driver after being down for several days, and the clock somehow got off by an hour. Might be a false alarm, although for some reason, I seem to be losing cache. "Time is simply the mechanism that keeps everything from happening all at once." |

I am going to assume that boinc.berkeley.edu suddenly being offline as well is unrelated. It isn't down for me at this time, but I have seen database errors, and pages claiming the whole thing was down. Then 2 seconds later it would load normally. Something or someone is hitting the domain hard, has been doing that for a couple of days now. |

It had been down for a while & the eternal site places were indicating it was down as well.

Uh, oh... I noticed that too. Clicked the update button a couple time cycles. A nice number of wu's feel from the tree. |

How the hell can this validate? I think I see a pattern to this now, and only seems to affect MB. - new task starts - pending upload waiting - cpu hits load limit (90%) - cpu shuts tasks down until upload is done - then everything fires up again I'm seeing this over and over if 2 things are happening at once.
I have removed the 'suspend' when busy setting, and freed a core when running MB, and it's still complaining .... GRRRRR Funny thing is my SLOW AMD is just fine, it's my i5 that is doing it .. GRRRR |

I'm wondering ... I had report tasks immediately set on my i5. (I changed it) So does BOINC think the slot is empty after it is uploaded and just assume it has free access to the slot files to overwrite? Thus blanking them out? |

I'm wondering ... I had report tasks immediately set on my i5. (I changed it) No. We went into this in some detail (Ivan will confirm) while we were fixing LHC's CMS-dev application and the problems it was causing at other projects. Enable the <slot_debug> logging flag, and you will see that the slots are cleansed both when the old task finishes, and again before the new task starts. The only problem would be when stderr.txt grows to be more than 4 GB in size. If that happens, upgrade to BOINC v7.6.2, which can handle it. Edit, and before any of that happens, stderr.txt for the old task is read back from disk and copied into the statefile structure in memory. From there, it is written out peridically into client_state.xml, just in case BOINC is restarted before the report is accepted - that way, there's a persistent record so the report can be retried after maintenance is complete. |

Is there any advantage to raising the CPU% used in ati5_nocal other than doing the wu faster? |
Brent Norman Send message Joined: 1 Dec 99 Posts: 2786 Credit: 685,657,289 RAC: 835 |
That is really an open ended question ... Yes freeing up a core does help GPU performance, but does that empty core do more work than you gained? My i5 doesn't seem to boost the GPU enough to warrant a core shut down for 2 MB tasks. If I was running 3 or 4, then yes. If CPU heat is an issue, then shutdown a core. I think I do see an improvement in AP GPU tasks with 1 core shutdown, but it's hard to tell since those buggers are hard to get your hands on. One hint ... stop your network communication, run it for a few hours, make a change, run for a few hours ... it will give you a good idea of what your run times are changing. |

It always depends on the CPU/GPU combo. With a high end GPU you always benefit freeing a CPU core. With each crime and every kindness we birth our future. |

For nearly 24 hours i'm not getting *ANY* work for the CPU, only work for GPU! I didn't change anything, i don't get it... :/ Aloha, Uli |

For nearly 24 hours i'm not getting *ANY* work for the CPU, only work for GPU! The 'tasks limit in progress' reached for the GPU (or set WU cache)? |
Ulrich Metzner Send message Joined: 3 Jul 02 Posts: 1256 Credit: 13,565,513 RAC: 13 |
The 'tasks limit in progress' reached for the GPU (or set WU cache)?I have 2 CPUs and 2 GPUs and 139 tasks in progress. This is what i get: 08/07/2015 18:57:40 | SETI@home | Computation for task 19ja15ab.29055.20324.438086664197.12.134_1 finished Of course the single downloaded WU is for the GPU!? :( So my CPU crunches Milkyway, the backup project. Things get worse and worse... Aloha, Uli |

I attribute it to BOINC 7.2.33 which seems to be the best version I've come across. I gave it some more thought and realized sometime between using the Commode version and the regular version I had moved the BOINC Data folder to a 2nd hard drive. Maybe having the Data folder on a different HD than the OS makes a difference? I dunno, just trying to guess why I don't seem to be having the problem anymore... |

08/07/2015 19:14:55 | SETI@home | Finished upload of 19ja15ab.29055.20324.438086664197.12.199_1_0Look at this, i have selected to download other WUs, if AP is not available, which obviously works for the GPU but *NOT* for the CPU. This is server side related, *NOT* on my end! Aloha, Uli |

Don't look now, but we got a new dataset splitting off some AP work.......... Meow alert. "Time is simply the mechanism that keeps everything from happening all at once." |

I attribute it to BOINC 7.2.33 which seems to be the best version I've come across. Do you have a different setting for "write caching" on the 2nd drive? I remember speculating that write caching might be a factor, back when we were initially trying to diagnose the problem. Unfortunately, after trying it with the setting both enabled (my default) and disabled, I didn't find any difference in behavior so I pretty much discarded that theory. Maybe there's another drive setting that could be in play. |
