Since the AMD Threadripper2 has 16 cores (32 threads) that are not directly connected to ram I wonder if it would be possible to compile a "small memory foot print" version of the cpu app that could fit all the data and the executable into the cpu cache? I will freely admit, even if it is possible then we would have to come up with a way to run those only in those cpus unless they run virtually as fast as the regular version.

Thank you for the reminder! For my dedicated Seti machines I wish I could download enough tasks to get past a day long outage. Then I wouldn't be bothered by wanting to "keep them busy". Tom A proud member of the OFA (Old Farts Association). |

I know that World Community Grid doesn't like to share with other Boinc projects. But it has lots of cancer and disease research projects. Is there another project with similar research that is "better behaved"? Thank you. Tom A proud member of the OFA (Old Farts Association). |

BOINC will do exactly what you ask it to do, so if you ask it for a two day cache and your main is out, it will make a two day cache of your backup. As those deadlines will be different, it will likely go into EDF mode and crunch the backup until done! Unfortunately we can't set different caches for different projects. I do not think that is quite correct, in the case when you set share 0 for your backup project. In that case, it will d/l only 1 WU at a time for the backup (at least, that's the way it used to be, back when I was doing backup projects). |

Even when I set it to "0" Eienstein@home will regularly download as much as I asked for (0.5 days for instance). However, World Community Gird sends a message that says "your settings don't allow us to send you anything" if I set it's priority to 0. :( Tom A proud member of the OFA (Old Farts Association). |

Even when I set it to "0" Eienstein@home will regularly download as much as I asked for (0.5 days for instance). Sorry, No you are wrong, If you set E@H to 0 (zero) it DL only 1 WU per GPU and only when the S@H cache is totally empty. That's the way most of us work with a backup project. World Community Grid does not allow you to seet it to 0 (zero) instead. So you can't use it as a backup project. |

Even when I set it to "0" Eienstein@home will regularly download as much as I asked for (0.5 days for instance). That doesn't match what I experience from Einstein. If set to "0", it will still download my global cache setting of 1 day. Einstein does not obey the BOINC rules on many things. I have to set NNT at all times and then Allow tasks when my cache gets low. It still sends too many for that single download and I have to abort 80-100 tasks immediately after resetting NNT. If I don't reduce my Einstein task cache below 200 or so, it will reduce my cache requests for Seti and not allow my standard Seti cache limit.

If I remember correctly that downloading more than 1 work unit per GPU was an error issue with BOINC. Can't remember where I saw it, Juan is correct that if BOINC is working correctly, then it only downloads 1 work unit per GPU. That said....I have had the issue that Keith mentions but haven't had it in a while. So, was it an issue with BOINC before 7.4.44?? |

You do something wrong, look my host and see, it only DL 1 WU per GPU when no Seti work is available. Where you set the E@H preferences? Could be because the local preferences override the global ones. |

That is up till just last night in my attempt to circumvent the BOINC bug that prevents any cpu task from running with my excluded gpus on the new TR host.

No, can't be local preferences - Resource Share isn't included in those settings. RS can only be set via the project web site - though you do have four venues to get confused between. |

Greetings, I'm in a bit of a quandary about BOINCStats. According to BOINCStats I have a total credits over all projects at 10Mil+. I looked at the values on my account page for all projects and it barely adds up to maybe 9Mil+. BOINCStats states I am second in my team. My roommate has the #1 spot and I am just as confused about her totals too. The projects list on her account page barely adds up to 5Mil+ yet BOINCStats says she is at 24Mil+. What gives? Am I reading all this wrong? What? I'm so confused.... Have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

What gives? Am I reading all this wrong? What? I'm so confused.... Make sure you're looking at the right stats. Seti main only, Seti main & Seti Beta, or all projects, with or without ASICs, etc. Grant Darwin NT |

I have always seen Einstein send only 1 task when set to a RS of 0. If it isn't 0 is when it gets aggressive. |

I looked and several of us are running different version numbers of the Boinc Manager under Linux. It maybe our experiences are different because out version numbers are different? Tom A proud member of the OFA (Old Farts Association). |

I looked and several of us are running different version numbers of the Boinc Manager under Linux. Absolutely. The differences in the BOINC source code branches can be extreme. So no way to compare different versions of BOINC behaving exactly the same under the same circumstances.

I use BOINC 7.4.44 under Linux and 2x BOINC 7.14.2 under Win10 and a setting of 0 with Einstein, Milkyway and WCG works as it should, I only get work when there´s no SETI jobs and only 1 at a time. |

Do you also run other projects concurrently on each host with Seti? I do and likely why I see the difference in behavior. I've learned long ago what works and what doesn't work with Einstein on my hosts. I might be a corner case. Seems likely since I am always finding ways to break BOINC as my recent problems with project_max_concurrent and exclude_gpus.

What gives? Am I reading all this wrong? What? I'm so confused.... Hi Grant, All the numbers are for all projects worked or working to date. The numbers are not specific to one project or another. I'm trying to dig a little deeper to find a reason why the numbers are so out of whack. Thanks Grant and have a great day! :) Siran [edit] Ok, got it figured out. BOINCStats is adding in totals from retired projects and SETI account pages do not. So the numbers are correct. [/edit] CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS?
