1 PC will not request work ,even if other waiting units and 1 executing suspended. BOINC 7.16.6 on Ubuntu 20.04 newly built. WCG CPU units working OK. Can anyone help interpret and debug.

1 PC will not request work ,even if other waiting units and 1 executing suspended. A couple of things first your cache size on the pc come into play which that list says nothing about ie the 'store at least___days of work' and the 'store up to an additional ___days of work' if you already have enough work from your other projects then Rosetta can't send you any more work or your cache would overfill. The other thing is you seem to be using a zero resource share for alot of projects and a ONE for Rosetta, there's not a whole of wiggle room there so I would bump up Rosetta to 100 and then you should get Rosetta work almost everytime they have work for your pc again depending on your cache sizes. |

Thanks Mikey. Work share is 900 WCG and 100 Rosetta with 1.2 plus .1 days work. Currently about .5 day loaded as WCG units limited by number to 8. Also I tried suspending waiting WCG units and 1 running unit and still not requesting. Paul. |

1 PC will not request work ,even if other waiting units and 1 executing suspended.BOINC will not request work for a project when a Task is suspended because it has no way of knowing when it will be unsuspended, and no way of knowing if that Task can be returned in time, let alone any new work. With the number of projects you are running, the large size of your cache, and the limited number of cores/threads your systems have, and the Resource share settings you are using, it's very unlikely that Rosetta will be running on your systems at all times. With the number of projects you are attached to you would be better off with no cache at all. I'd suggest 0.01 days and 0.0 additional days. If you wish to do more Rosetta work, you need to increase it's Resource Share (from memory the largest possible value is 1000), or reduce the Resource Share of the others (WCG doesn't follow the usual BOINC method for adjusting this, so i've no idea how you would accomplish that). Keep in mind Resource share is a ratio- not a percentage. The other problem is a Rosetta one- for some time now new Tasks have been misconfigured to require way more RAM than they actually need to run, resulting in many system with smaller amounts of system RAM no longer being able to get work, or only being able to get a limited number of Tasks, even if they have plenty of available cores/threads. Several of your systems fall in to this category. Increasing the amount of RAM available to BOINC may help. In your account, Computing preferences, Memory When computer is in use, use at most 95 %
When computer is not in use, use at most 95 %
Leave non-GPU tasks in memory while suspended Leave unselected.
Page/swap file: use at most 75 %But until the researchers sending out these mis-configured Tasks fix it at their end, it's going to remain a problem.Also your most recently added system needs to have the BOINC Benchmarks run in order for it to receive a reasonable amount of Credit for work done; it's still using the default values.

Thanks Grant. Only tasks I have are 8 WCG, 4 running so I tried suspending those to force Rosetta to fetch. System has been running for several days, just forced a benchmark to be sure, still won't request. Other systems request and get some units but often see memory or disk message as modest PCs. Paul. |

Only tasks I have are 8 WCG, 4 running so I tried suspending those to force Rosetta to fetch.The default Runtime for Rosetta work is 8 hours, the deadlines are 3 days. With that many WCG tasks loaded up, with only 4 cores/threads, it's not going to request more work until it can be sure it will be able to return it in time, and it won't request more Seti work if has to complete more work for other projects in order to meet you Resource Share settings. All it is doing is trying to meet the the settings you have made. The smaller your cache, and the less projects you run, the sooner your Resource Share settings will be met (as in weeks). The larger the cache & the more projects, the longer it will take (as in months). Micromanaging this actually makes them worse. Set your cache to zero, change you Resource Share settings to favour Rosetta, then once it has cleared the present backlog of WCG work it will (when it can) start doing more Rosetta work. Just let it do it's thing once you have set your preferences. The fact that there are issues with the configured requirements for Rosetta Tasks at present is just gong to result in less Rosetta work being done at times, then times when it's mostly Rosetta work. But over time, your Resource Share settings will be met. But whether that time frame is weeks or many months, depends on the settings you choose & whether or you you micromanage things.

Sorted. I had edited app_config to limit Rosetta to 1 task running with BoincTasks. This was OK on earlier versions of BOINC but this version silently failed. Paul. |

Sorted.Yeah, i guess that would do it. Although i can't see any sign in the work request logs where it mentions such a limit. The only thing is this line 13465 Rosetta@home 16/04/2021 17:42:27 [work_fetch] using MC shortfall 0.000000 instead of shortfall 272837.976021Where it replaces the 272837.976021 shortfall with a value of 0, ie no shortfall. So no need for new work. Grant Darwin NT |

It was not clear to me in the logs but checking showed app_config entries with GPU sections added and mangled. That was OK in previous BOINC versions for CPU projects but bad format caused 7.16.6 to not request work. |
