I know that we went months clamoring for work units. Now for some reason I am getting too many. For instance, I have 18 left for today. Tomorrow I have maybe 30? And I have 23 for tomorrow all due at the same time (within 1 second of each other).
What do I need to do to make sure my machine is only getting the number of units it can actually process and deliver on time? I have also noticed the estimated time for these are like 2:23:52, but the actual elapsed time is like double this. Can someone help me figure out how to limit things and possibly do a better job of estimating? |

Using Boinc Manager click Options/Computing preferences and a panel will open. Near the bottom there is a section called Other. Reduce the store at least and store up to an additional days of work fields. Experiment to find a sweet spot. I have mine at 0.2
----------------------------------------On the faster Ryzen 9 I use at least 0.2 days and 0.4 additional days of work. I'm not sure of this but then I click Read local prefs file and Read config files. It does not hurt anything. [Edit 3 times, last edit by BobbyB at Sep 7, 2022 2:56:47 PM] |

Let us know if you need to know how to do that. Cheers

Let us know if you need to know how to do that I'm interested. How? |

From the OVERVIEW PAGE:
----------------------------------------Scroll down to VIEW ALL DEVICES Click on DEVICE MANAGER Select INSTALLED/REGISTERED DEVICE ANYTIME (all devices) Click on REFRESH. You should see a listing of all the computers on your account along with their currently assigned profile. (If desired, Clicking on the computer name will allow you to change the assigned profile.) Clicking on the profile NAME (DEFAULT, SCHOOL, WORK or HOME) will allow you to modify the settings. The PROJECT LIMITS is what I believe you are looking to access/change and to get to those, you need to scroll down to near the bottom of your selected profile and make your changes accordingly. (minimum of one (1), maximum of unlimited) Selecting WHICH PROJECTS is done near the beginning of the profile. When you finish, click on SAVE. You should be able to go to the list of profiles from there. [ETA] If your computer is not listed, it has probably been assigned the DEFAULT profile. So just work with that for now. Good luck and happy crunching! [Edit 1 times, last edit by bfmorse at Sep 7, 2022 10:01:17 PM] |

Ah! OK that thing. Yes I remember doing that in the early days when I joined WCG. I've already tweaked that.
----------------------------------------I thought it was something on each machine in one of those XML files which is what Boinc Manager does with those settings I mentioned. I imagined a type of profile on each machine like the 4 profiles you describe above which would override the system profiles in WCG What is there is sufficient for me with only 4 machines, [Edit 1 times, last edit by BobbyB at Sep 8, 2022 3:36:01 PM] |

There should not be a need to make ANY changes from the default changes of the BOINC agent.
----------------------------------------All the current issues are on the server (WCG/Krembil) side, and if someone is messing with the settings in the client, they should be on their own, because according to Murphy's law, what ever changes you make, it will at some point come back to haunt you...

Running the benchmarks does no harm.
If he is getting too many WUs and can't deliver them on time then it helps no one. Others could be crunching the ones he has to give up. |

I noticed the estimated time is a little off. Benchmark doesn't fully fix wrong estimated runtime. I believe they runtime estimation may be based on previous results.
A few things can affect runtime. -- Simultaneous MultiThreading (SMT), 2 threads for each cores. -- RAM speed can affect runtime for some projects. Running 32 ARP1 task on AMD Ryzen 5950x (32 threads) takes 25 hours on dual channel DDR4 3600 MT/s speed, but running just 2 ARP1 task + 30 MCM1 task is a fast 12 hours for ARP1 tasks. World Community Grid profile can limit number of tasks, but not most other BOINC websites. BOINC Options, computing preferences, store 0.1 days, and store additional 0.1 days., maybe more or less. In app_config.xml, if max_concurrent used old BOINC version, 7.16.16 or older, then this can cause too much task problem. Update to 7.20.2 or newer BOINC version to fix most of this problem. |
