Re: [Dorset] Next Meeting - COVID-19 Situation
Are people interested in getting this going? I could make us a poll to sort out how we're doing it. I like the idea of subgroups - I think it'd be difficult otherwise cos we often have subgroups having mini-conversations. That way we could also switch between conversations at will. I was also wondering if people might like to do these more often, seeing as we're all pretty much stuck at home for the foreseeable future?

Ralph, Whenever I can't find the answer in Google, you pop up and show the answer in Google... :-) From the link: In BOINC, recent average credit (RAC) is computed as an exponentially weighted average with a half-life of one week. In other words, if an entity is not granted any credit for one week, its RAC will decline by 50%. An entity's RAC is updated whenever credit is granted. To avoid expensive database queries, the update is not able to scan the history of previous credit grants. The only information available is the previous RAC, and the time it was computed. BOINC uses the following approximation (all times are in days). -- Terry Coles -- Next meeting: BEC, Bournemouth, Tuesday, post-lurgi 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

As best I can tell by looking at my own figures, the "Work done for this project" figure shown in your screenshot corresponds to the total amount of credit awarded to your user account. The terms "work done" and "credit" seem to be interchangeable. There are two sources of delay in this figure: 1. Credit is only awarded after an individual work unit/task has been completed, not during the processing. 2. The actual statistics display is infrequently updated. The client is not in constant contact with the server. It seems the statistics are only updated when the client completes work and requests more work to download, but it seems it requests the latest statistics *before* telling the server about the work it has just completed, so that that work doesn't get reflected in the statistics until the *next* update, many hours later! Under "Project Commands", there is an "Update" command, which, among other things, brings in the latest statistics if you really must have them, but I get the impression it might be best not to bother the server too much by pressing it a lot. You can also see the most up-to-date figures (but not a graph) on your online account in a Web browser.

Re: [Dorset] BOINC Statistics
I can't remember, but I ran it for years on a raspberry pi. There is a delay, so it might be you were awarded 2 days of work at once or something?

Re: [Dorset] BOINC Statistics
Terry, Work done is more of a measure of the computational difficulty of the tasks you completed, not the number of tasks - some tasks are shorter/simpler than others :) Hamish On 29/03/2020 10:26, Terry Coles wrote: > Hi, > > Is anyone else out there using the BOINC client?

[Dorset] BOINC Statistics
Hi, Is anyone else out there using the BOINC client? As related a few days ago I had problems with F@H (which Tim is using) so I installed BOINC from the repository and have been running it ever since. As also related, I found it initially overworked my CPUs and caused serious overheating so I throttled back. For several days the 'Work done for this project' read 0 because the first Task was yet to complete. Yesterday morning I was informed that the work done was 1, as expected, but I definitely didn't expect to log in this morning and be told that the work done was now 762! I've opened the Help, but the Views shown see https://boinc.berkeley.edu/wiki/ Simple_view[1] do not match what I get and the Help is not particularly helpful. In particular I can't find anything that explains what the Work done number actually means. Here (http://hadrian-way.co.uk/Misc/[2]) are screenshots of what my Views look like, including the remarkable change in Statistics since Friday. Can anyone shed any light on this? -- Terry Coles [1] https://boinc.berkeley.edu/wiki/Simple_view [2] http://hadrian-way.co.uk/Misc/ -- Next meeting: BEC, Bournemouth, Tuesday, post-lurgi 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
