There seems to be a bit of a problem with cuda22 and cuda23 work finishing in errors on other rigs, an example http://setiathome.berkeley.edu/workunit.php?wuid=1256169015, and those pesky GTX 560Ti's are still doing their thing. They don't look to have been. Also my 1st inconclusive, http://setiathome.berkeley.edu/workunit.php?wuid=1256474447. :-( The 560Ti in that inconclusive has been a very long term horrid rig but the other was fine until V7. ;-( Cheers. |

Now you can ponder whether it's good that the infinite loop on temporary exits that I bugrepped got fixed, or whether it would be preferable the machine choked and got the next full chache after timeout... As for the problem 560ti, looks like the validator doing its job there. The Ati host there I believe (with limited knowledge on the issue) is running insufficient SDK, might be a more serious situation, though I don't know the details. Responsability of the other part of the team. I think I saw a bugrep (to Eric) somewhere in the Chaos and Mayhem, so it's being looked into.

EDT- just had a look at my inconclusives- and they're mostly Cuda50s not validating against opencl_ati_sah with a few Cuda42/32 etc types in the mix- but 90%+ are opencl_ati_sah results.hmmm, looks like the same ati sitation. Just had a further look at my inconclusives. One V7 Cuda42 v a V7 v7.00 inconclusive. The others were a v7.00 & a Cuda42 coming up inconclusive against opencl_ati5_sah results. EDIT- for those that are interested. Of 20 v7 inconclusives, 18 of them are against a v7 opencl_ati_ of one type or another. Grant Darwin NT |

Claggy See my advice to use 'venues' in response to another post of yours. I will say something though that I think you should look at. You misunderstand what the 0.02, or 0.10, or whatever means or does. It does not limit CPU usage. It controls BOINC's scheduling. If you run 50 GPU tasks at once (first figure), or 10 GPU tasks at once (second figure), the CPU bits will add up to a whole 1.00 CPU, and BOINC will stop running one CPU task (will run one fewer CPU task than normal). That's all. The 0.02 figure is one we've been putting in published and distributed app_info files (e.g. via the installer) for years. Basically, it stops the CPU application count jumping all over the place. NVidia applications are normally happy to run even when every CPU core has a BOINC task running on it (ATI experience may be different). If your experience is different - say for a host with more than one high-power GPU, but a weak CPU, which I would call an unbalanced build - reduce the active CPU count yourself by adjusting the On multiprocessors, use at most Enforced by version 6.1+ 100% of the processors for the venue that host is assigned to. |

I think the kitties have gone all stock until the new installer rolls out. Many others might be induced to do as well. It won't do any good to continue to wank those that need to spend their time writing installer code rather than to ask repetitive questions here. Meow, and goodnight.

I think the kitties have gone all stock until the new installer rolls out. Yes I better stop reading NC and trying to answer the same silly question for the 15th time, or we won't be able to hold the Monday deadline. It's been said that out of the three things money, time and quality only two can be achieved. Since we don;t get any money two remain, out of which one can be achibved. Guess. Over and out.

I'd suggest the Monday after next would be a better target. With a week of people running stock (or not at all) the auto application optimisation selection should have had a chance to do it's thing & things should be settled down, somewhat. Grant Darwin NT |

EDIT- for those that are interested. Just got some more inconlusives, however these are Cuda50 v other Cuda applications. One of which involves 2 GTX 560Ti's. setiathome enhanced x41zc, Cuda 3.20 (314.22 driver) Spike count: 0 Autocorr count: 2 Pulse count: 0 Triplet count: 1 Gaussian count: 0 setiathome enhanced x41zc, Cuda 5.00 (320.18 driver) Spike count: 1 Autocorr count: 2 Pulse count: 0 Triplet count: 1 Gaussian count: 0 Grant Darwin NT |

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? The AP WU is currently 24% complete and has been running for 1.5 hours, so it is heading for about 6 hours to complete. Does this sound right for a GTX460 running at 857MHz? ![]() |

Can't comment on timings, I'll leave that for the OpenCL specialists. |

Have now taken to manually aborting: William, Doesn't appear to be the case. Aborting them is working quite well. The appearances of cuda50 and cuda23 WU is now almost non existent. Haven't had a cuda23 WU in ages ... and cuda50 is now only popping up once in a blue moon ... seems to work better than processing the WUs ... would recommend this approach to anyone to try :) |

Claggy Yep, I'm aware of that ... The 0.02 figure is one we've been putting in published and distributed app_info files (e.g. via the installer) for years. Yep, I'm aware of that too...
Yep, tried reducing active CPUs as well ... Best results obtained by changing 0.02 CPU to 0.20 CPU. In doing this, RAC increased to highest levels of all configurations that I tried. QED in my case. Have a look at Smallpox, it's an i7 3930K with 2 x GTX580s (ranked around #13). You would have to say that it's a bloody good performer wouldn't you given the GPU tech. cheers mate ... ps. that is before v7 migration which throws some uncertainty into the mix. |

How exactly do you attribute effect to cause, with that one? I'm genuinely interested, but sceptical. If there's a real relationship (both demonstratable and explicable, scientifically), then we ought to change the installer we're writing. |

Have now taken to manually aborting: That is because aborts count as errors against your quota. edit: I suggest to let at least a few through, slow as they might be. A person who won't read has no advantage over one who can't read. (Mark Twain) |

Richard, I have changed things at my end over time and watched the results. In essence I do not care if you do not believe me or do not want to take what I say at face value. That is your choice and I accept it. I can only speak from my experience and my experience with these machines tells me that 0.03 CPU or something similar reduces processing capabilities for the GPUs ... after a particular value it becomes irrelevant however I chose to set it higher than needed. When the optimised installer comes out and I will once again be able to set up the system to the manner I like, I will revert to 0.20 CPU and then experiment for myself from there. cheers |

Freeing up a second CPU core made no difference. Is this normal? Thanks Richard. In the end it finished normally in 3.5 hours. 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. Not sure why the apparent GPU usage was so low, but it has returned to 70-80% now that the GPU is cruching MBs again. ![]() |
