One completed so far. Very nice GPU utilization on GTX 780Ti w/ Win7 at ~85% with CPU crunching at 75%. | |

I just recently created an application for my Dell XPS 730x computer, which is capable of controlling the XPS System Fan, ramping fan up and throttling fan down, all based on the GPU Temp of my GTX 660 Ti. | |

Currently chewing one too, very nice utilization: | |

My 780Ti does very good with these as well, 88-90% GPU load and using 1150MB of memory. Temperature is a bit higher, now 76-77°, is with other WU's 72-74°. But ambient temperature is 29°C. | |

Stefan, excellent research choice! | |

Very good job and idea. | |

From the previous simulations we found out that we need to produce longer simulations to analyze their interactions well, so I am submitting some more of these workunits. Should fill up the queue for a while :) | |

Thank you for the follow up - we appreciate seeing the continuing progress and evolution of this experiment. | |

These longer BARNA's run smooth on my GTX780Ti. Steady 88% GPU load, using ~1100MB RAM and boost the card at steady 73°C (thanks to Jeremy Z). Completed in around 5 and a half hours in Win7 with "old" 331.82 driver. | |

Thanks :) Sorry I didn't make it clear, but the single WUs steps that you calculate are actually the same length as the older ones. They are just configured to run more steps, meaning that they will be longer in the end. So in theory from your point of view they should take roughly the same time as before (plus minus half an hour?). | |

Completed in around 5 and a half hours in Win7 with "old" 331.82 driver. That's quick. It's looking like about 8h 45min on my GTX770 (W7x64 1163MHz Boost) 337.50. Probably down to not using SWAN_SYNC, running 7 CPU tasks, using slow DDR and being on a PCIE2 bus (older controller). GPU usage is a bit spiky. When the WU completes I'll enable SWAN_SYNC, reduce the CPU usage and reboot, to see how the next one fares. Stefan, I take it that you reduced the detail/accuracy making each step quicker? ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help | |

No, simulations should be same accuracy. What I call "steps" or sometime "chain-steps" are consecutive pieces of a WU. This means that you get sent a WU, finish it, and it is sent to another user to continue from your endpoint. If you stick all these steps together you have one very long simulation. So I just told GPUGRID to continue sending out the ends of your simulations to other users for quite some while so that I get very long simulations. | |

My 770 is running at 1149.7MHz (GPU-Z), 93% load. But as I still us the older 331.82 driver, I can not use SWAN_SYNC. The CPU is a Haswell from last year, the i7-4770K but I am still using old RAM 799.6MHz, 8GB in total. The CPU is only doing four Rosetta WU's, and two for GPUGRID, as I have also a 780Ti in this PC. Both using 0.749CPU's. So indeed skgiven that helps a bit in speeding things up (less CPU use, we have both experimented with that). But I guess its the driver. With the latest drivers, the 780Ti is hampered, reported by several other crunchers, and I saw that too when installed 337.50 beta and reverted back two days later. | |

Aha, now I understand, thanks for the explanation Stefan. Although 5.5 hours does indeed sound too short... I will take a look. Or perhaps you did find a way to get more out of the 780Ti, the "wonder card" that runs not optimal under Windows later then XP... ____________ Greetings from TJ | |

As expected I saw an improvement on runtime from using the better settings: | |

The BARNA projects running on Dec. 2014 were at like 60/100 steps. | |

They are finished. We simulated more than enough and now it's time to analyse them with some collaborators. Thank you very much for crunching them :) | |

That would be explained in the BNBS thread. I guess you talks about this posting: I can't get new tasks on my Linux host (with a GTX 1080), while there's a plenty of workunits in the queue. The big difference to my current observation though is that all my hosts do in fact still download BNBS tasks. So, this time, they are not just shown on the project status page, they really exist and are available for download. | |

That would be explained in the BNBS thread. No, I was talking about the precise message 45808 that my link pointed to: In case anyone is wondering what these WUs are, we are running some extra simulations on the Barnase Barstar system (previously called BARNA: http://gpugrid.net/forum_thread.php?id=3709#36142 ) to answer some questions of the reviewers. If the results get us through the review process this will be a major publication :) | |

At first view it seems that Pascal cards may benefit from this kind of job. My GTX 1080 is now utilized to 90-95% (even with WDDM) which is an amazing plus of 10% compared to other long runs. | |

How can this be? Because Erich has re-activated a two year old thread relating to the original research run. The parameters for the new 'pre-publication review questions' run - more properly discussed in the new thread - are likely to have been set differently, to take advantage of the increased computing power available in 2016 compared with what we were running in 2014. | |

I see... looked at that way the 8 hours of the 1080 seem to be a good value. I wonder what time the "older" hi-end GPUs like a 780ti, 980 and 980ti need to finish this job. Just from the specs, the Pascal should have a major advantage over these cards, but in practice a 1080 was hardly faster. At least as far as regular long runs concerned. | |

I just started up my GTX 970 running SDOERR_BNBS-2-4-RND5876_0 under Ubuntu 16.10. At 1.5 hours, it shows 8.8% complete, or 17 hours total. I am not sure how the Nvidia X Server Settings compare to GPU-Z, but it shows a Graphics Clock of 1366 MHz and a GPU Utilization of about 95-96%. So I think that is the card to use for me; even the 960s are a bit slow for this series. | |

The GTX 970 in one my PCs needs between 17 and 18 hours for these jobs; | |

I run 2 at a time per card on my 980Tis and these are running 17-21 hours each so far. But the credit reward is amazing! ____________ 1 Corinthians 9:16 "For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel!"

1060-3GB 18h 20min on Linux, with mostly 1 CPU task running. GPU ran just shy of stock with fan speed increased. Utilization was up to 98%. Would likely perform a bit better on a higher end system. Seemed a bit less susceptible to CPU usage. Did take 30% longer with 3/3 CPU tasks running, but with other WU's GPU utilization would have dropped to 60% with just 2 CPU tasks running and with 3 running it was a wast of time (10-20% GPU usage). Good credit as well. Overall these are very friendly tasks. | |
