Re: Daily WorkUnit Flow Information

I can see that MCM is flowing at a great rate now. Unfortunately it isn't enough.

I'm running MCM one at a time, just to keep my machine asking for other tasks, and I can't even get my one MCM reliably .

Two reasons the flow of MCM can not keep up with demand are 1) It is currrently the only project running and 2) The average run time per unit in the last couple of days appears to be about 80% of the previous work units which means machines are requesting work units much more frequently than in the past.

Whilst some BOINC projects might have effectively limitless data streams, that's not so for WCG :-( so there's something else we might need to think about... SARC1 dataset has been in use for several years now, and the faster we consume tasks the sooner the SARC1 supply will be exhausted... Do we know whether a replacement dataset is already prepared?

Re: Daily WorkUnit Flow Information

I haven't gotten any WUs in hours.

Re: Daily WorkUnit Flow Information

I wondered about intermittent supply, so I've just had a look through the boinc.log files on the 4 systems that try to get work from WCG, looking for "Tasks are committed to other platforms" messages during 11th September (BST [UTC+1]). These are all Linux systems, by the way...

Based on what I saw, there still seems to be a [tiny?] set of retries for SCC1, but I suspect they may all be for Android :-)

More to the point re MCM1, I found quite a few occasions where the "other platforms" message was present, SCC1 reported no tasks available and MCM1 was missing -- perhaps we've reached another "here come lots of missed-deadline retries" period, in which case that might explain apparent slowing of available work.

Unfortunately, I suspect Mac users might get the worst of that :-(

I saw quite a few MCM1 "other platforms" incidents between 07:00 and 20:00 (UTC) , with a much smaller number outside that period. I have quotas set in my device profiles, and I think it will report "No tasks" when my quota is met, even if tasks are committed to other platforms, so my observations may be under-reporting...

As it happens, I currently have no problems keeping my [small] quotas topped up, although it has sometimes taken a couple of hours for a completed, reported task to be replaced. However, I note that Sgt. Joe has just posted about [most of] his Linux boxes having run dry, so I also wonder if there's an option in play giving preference to small requests...

Cheers - Al.

[Edit - revised the top-up comment (and promptedpromoted it from a P.S.) when I saw Sgt. Joe's post elsewhere...]

Re: Daily WorkUnit Flow Information

The forum is back. Thanks Tech people.

Looks like MCM and some OPG WUs are going out.

Re: Daily WorkUnit Flow Information

well, MCM is available, but not in quantities like before. My cpu's are not dry, but they seem to hover much closer to it than say 10 days ago.

48 cores, 48 tasks running, 19 tasks waiting
40 cores, 40 tasks running, 15 tasks waiting

I used to see about 950 tasks waiting, which was a comfortable buffer, given the frequency of weekend problems. It's friday again, and buffers are low. What gives?

Re: Daily WorkUnit Flow Information

Based on the Sent/Due/Returned Dates in the component WU's, sadly it appears that some individuals are still running six day queues.

To maximize my chance of successfully completing those WU's assigned to me before they get aborted, I run a queue of ZERO DAYS and am mostly successful in getting things processed in time.

Re: Daily WorkUnit Flow Information

Even if it were a conscious decision to override buffer settings on clients, it'd be nice if there was some communication about that.
