. . . Hello Richard, . . It is doing so as we speak. But I was just wondering. :) |

Hey Rasputin42, . . SoG is running nicely on this machine but blc5 certainly take longer than blc6, they fooled me into thinking something was wrong at one point. I am wondering how blc7 will behave as I have a lot of them coming up. |

With any "new" GPU installation it is worth running with only one task for a few days just to see what the thing will do in the base situation, then step it up to two for a few more days, finally if that is OK, push up to three. As Mike says I very much doubt that a GTX720M is up to running more than one task at a time. . . My GT730 is only barely capable of running doubles, and comes to grief when a Guppie swims by. |

How many times must this be said - the critical thing with GPUs is not MEMORY, but the number of GPU "cores" and their management. . . FWIW, I received the suggestion to run -sbs 512 on my GTX950 to persuade Guppies to play nice. But it wanted more than the 2048MB on the card and it was doing that, dropping out of WUs and leaving them in "waiting to run" state. . . The max it will support is -sbs 384 so it may be a lack of sufficient memory, worth checking it out. |

Wait for something that works better, I get the same thing, only time to completion becomes days, instead of minutes, I tried 3, then 6, then 33, same result, I can't figure this out, I just went back to cuda42, I give up. Zoom, I would suggest posting your entire commandline rather than just snips of it. It's hard to tell what the computer see when you only post a portion of it. |

My main problem, even though I have the sleep command running, is that I have a gpu wu 'running HP' and a gpu wu in 'waiting to run', it's probably nothing, but I thought I'd mention it. I have 1.5GB on hand in the gtx580, of that 935MB is being used(while crunching), I also have 512 cuda cores(in case anyone needs to know). I'll try 2, instead of 3. Savoir-Faire is everywhere!

564MB of memory used while under 0.45, vs 935MB. I'm running 2 wu's on the PNY LC 580 card now, though I'd rather run 3... Savoir-Faire is everywhere! The T1 Trust, T1 Class 4-4-4-4 #5550, America's First HST |

-use_sleep -instances_per_device N: 2 I think, that should be: -use_sleep -instances_per_device 2 |

-use_sleep -instances_per_device N: 2 Rasputin is correct. Zoom try this -use_sleep -sbs 512 -total_GPU_instances_num 2 -instance_per_device 2 Edit.. Only 1 GPU in your machine correct? |

You can always decrease the -sbs to 256 if you want and see if that works better |

I have noticed, that when running 2 instances of sog, it runs both tasks for a while and then one makes no progress any more.It finishes the other and starts a new one which it continues to process. The first one is still making no progress, but the elapsed time keeps going.If i suspend all other tasks, it finally makes progress again and eventually finishes. Link to such task result? |

-use_sleep -instances_per_device N: 2 So far, but yes. I'll try the one you provided Zalster. Savoir-Faire is everywhere! The T1 Trust, T1 Class 4-4-4-4 #5550, America's First HST |

I will have to set it up again.Currently doing cuda50. |

Stephen's message 1794739 earlier, about VRAM overcommit, may be relevant. Link to result would be helpful - we can check if it's a BOINC client which supports temporary exit. |

A habit to post at least link to result under question should be developed. App prints how much memory it uses for particular task in its stderr. Regarding SoG task progress: if task is VHAR and processing enters in SoG-only phase when it will enqueue all work to be done for particular task to GPU and then await task completion. What BOINC shows - unrelevant (as we know it shows its own guesses). Cause there is no lack of work for GPU to do even from single task there is nothing bad if runtime decides to finish kernel sequence from one task before switching to another (even if it's real effect that I strongly doubt to be so). There is no such thing as pre-emptive context switching in GPU so far AFAIK after all. |

http://setiathome.berkeley.edu/result.php?resultid=4973141178 This might be one of them, but no guarantee.I had to use the version you issued to not get stuck.https://setiathome.berkeley.edu/forum_thread.php?id=79629&postid=1793393 I will do a fresh one. |

-use_sleep -instances_per_device N: 2 I modified the sbs setting first to 256(from 512), then to 192, 2 wu's at 192 are using 864MB of the gtx580 ram, 256 used about 996MB, 512 used 1249MB. After I had installed the line with sbs in it and shut down and restarted Boinc, two cuda42 gpu wu's went into 'waiting to run' mode, and a pair of Guppi's took over. Savoir-Faire is everywhere!

http://setiathome.berkeley.edu/result.php?resultid=4973141178 No errors or restarts for posted result. It just OK with ~52min of elapsed time and ~3min CPU time (not bad too). EDIT and with -sbs 256 it uses: Currently allocated 357 MB for GPU buffers |

No matter what I do, it's waiting to run, then one runs really slow, no cpu% and becomes waiting, Zalster tried, but nothing works here, I'm going back to cuda 42, that works... Let Me know when this works and doesn't require a degree in computer programming to crunch with... Bye. Savoir-Faire is everywhere! The T1 Trust, T1 Class 4-4-4-4 #5550, America's First HST |
