. . I am now very new to Einstein but it must need some tweaking because my runtimes are far longer than Blc tasks and the credits don't look that good, in fact they seem about comparable to Seti. Overnight I accrued about 10,000 on a machine that does 31,000 a day on Seti. Looking at the monitors (afterburner) the CPU is overcommitted and the GPU usage is eratic and low. . . Thank you for that information. Though I don't see that running doubles on this machine would be feasible as the CPU is 100% committed just running singles. A pity about that. But I might try the Einstein beta testing option. Though right now I am going to try Seti again to see if I can get some work now that Eric has affected some sort of work around for the problem.

i just noticed that my main cruncher with 2x1070 is not getting Nvidia WU's anymore, no available tasks and it is processing Einstein meanwhile... No tweaking required or even possible. Just run the stock 1.17 app for Nvidia or better still, select to run Beta apps and get the 1.18 app which is about twice as fast as the 1.17 app. They are OpenCL apps so require at least one full CPU core to support a GPU task. Just like here on SETI. I find that two tasks per card is the optimum on Pascal. You can run an app_config.xml file just like SETI but I have identical parameters for both projects. 0.5 GPU and 1.0 CPU per task.

It turned out they had left the the power connector off the Optical drive which nearly blew the thing up, everything was running red hot (the IDE bus was still connected).( If the data cable was connected, but not the power cable the result would be- the Optical drive wouldn't work. That's all. Grant Darwin NT |

My main cruncher has been able to get some GPU work, but still hasn't been able to time a CPU request to match up with available work. It's a shame the PFB splitters can't keep up with demand (let alone get ahead of it), but a bit of work every now & then is still better than nothing at all. Grant Darwin NT |

If someone can stop those splitters congregating together on 1 file we'll all be a lot happier. That seems to be it. Used to be 4 Arecibo splitters could pump out as much as 45 new WU/sec, but ever since they started ganging up on files even with 7 splitters running they only occasionally peak at 40/s, generally they're around 35/s. And it would help splitting multiple different files by having plenty of different work available, not just all (or mostly) shorties, or VLARs. Grant Darwin NT |

If someone can stop those splitters congregating together on 1 file we'll all be a lot happier. One would think that having a splitter process "lock" a source file would be a no-brainer to put together. I used to do that sort of thing in networked MS-DOS 30 years ago by just using token files. |

Though I don't see that running doubles on this machine would be feasible as the CPU is 100% committed just running singles. . . With SoG the -use_sleep command solves that problem, but it can slow down processing a little bit. Worthwhile though if CPU cores are limited. Stephen :) |

. . Hmm, if the OpenCL app in Einstein supports app_config.xml I wonder if it also supports an app commandline file, and in particular the -use_sleep command ??? :) Otherwise the beta-test option sounds feasible. Stephen ?? |

That app_config.xml is a Boinc feature not seti, whilst -use_sleep and other comand lines are app specific. With each crime and every kindness we birth our future. |

It turned out they had left the the power connector off the Optical drive which nearly blew the thing up, everything was running red hot (the IDE bus was still connected).( . . Well it certainly didn't work but it certainly wasn't all. The Optical drive was hot, the IDE cable was hot, the PSU was hot. Clearly it was trying to draw much the power it needed from the IDE bus and wasn't at all happy. After restoring the power connection everything was much cooler. That is a pretty good indication. Stephen :( |

I've pulled the power connector from dozens of HDDs & optical drives over the years when troubleshooting while leaving the data cable connected and never had the issue you described. And given how a HDD or Optical drive is connected, I can't see how it could occur other than Pin20 shorting to Pin 19 or Pin22 on the motherboard (If Pin20 is even present there). On a standard IDE cable there was no power supplied to the drive- the hole for that pin was usually not even in the connector. On a standard IDE drive the pin wasn't even present. Grant Darwin NT |

Well you make a good argument but to me the high temps spoke louder :) . . considering what you say there was probably no chance of damage if I had not corrected the issue but I still felt much better that I had.

Good. PSU is in, installed it. 1. Forgot the CPU cable, I can tell you the system won't boot then. 2. One of the SATA power cables wasn't plugged in right, so only the DVD was found. But on the third try, everything started up... then windows told me that it had lost the hibernation file and that it had to boot normally and that everything that wasn't saved would go lost, would I like to continue? Like there's a choice... ;-) Anyway, will now go back to testing. |

Centurion is still under the weather so work is struggling out through the crack under the door. Strangely I'm getting work for my CPUs but very little for the GPUs, which are hammering through Beta work with great joy.

Looks like the current work mix is shorties & VLARs (although there are a couple of mid range units in my last download). If you do get any GPU work, it won't last long. And the odds of getting any GPU work are minimal. My main system has only been able to get work on 4 occasions since the outage. Grant Darwin NT |
