Yup - both struggle with the vast size of the database they have to plough through.

Another thing, and you consistently refuse to accept this - SETI@Home has NEVER promised us a continuous flow of work, so do not expect to see you cache's filled on ever call.
It's no good just splitting work if it's going to be withheld from those that want to process it.
Good morning everyone. I think Grant has a fair point there, and it would be better if barriers to receiving work only existed where they are strictly necessary. Having said that, the problem really only affects the rate work is completed for computers which can't cache enough work to last out the standard outage - and SETI didn't ask you to build those, either. Ever since SETI transferred to BOINC, the suggestion has been to transfer your resources to an alternative backup project when trouble strikes or available work is low. It will be interesting to see, starting tomorrow, how long the 'standard outage' lasts after the reorganisation last week.

Back to the problem at hand. As you might imagine, Eric and I have discussed scheduler issues sporadically over the years. I've looked back through the trail, and the most recent occasion was 26 October 2016, when

Eric Korpela wrote:
Yes, the patch did get applied to SETI beta yesterday. Things seem to be running well, so will probably be promoted to SETI main in the next day or two.
That was to do with fixing a totally different problem - the XML transmission of preferences between computers and projects, #1676 and #1470 - which had been troubling Einstein, but it needed changes here too. My guess is that we picked up the latest central scheduler code at that point. The problems over the botched application deployment a month or two later might have drawn attention to scheduler issues, and caused people to assume that the new Scheduler had arrived in December, too. I don't suppose anybody remembers stress-testing the Beta scheduler in October/November 2016, do they? Me neither.

I'll carry on plodding through code and tests as opportunities and inclination allow, but the belated arrival of Spring is tempting me to spend more time outside.

Possible solution?

Database 1-9903
Database 2-0408
Database 3-0913
Database 4-1418
Database 5-1923

Nice manageable chunks which would also alleviate the current database issues as database 5 will come into effect on this years anniversary & would make things fly :-)

Date splitting is the simplest, but it does not make it any easier because the objective is to compare spacial locations over time, so a spacial split, possibly with some degree of overlap, would be more sensible - a sort of "super pixel" in Nebual terms?

Understood but like everything else one has to make the best of what is available. As it stands, carrying on as is, the time will come when the database will be too large to handle.

Sometimes compromise is more than acceptable & don't forget ALL the data is still available (for when better solutions become available).

At least with it split, it will only be a matter of creating the right tables :-)

Edit 2: Also after an xx amount of time, the only database that will require maintenance/backup will be the current one which would also simplify the weekly outage :-)

You're mixing databases again, as many have done before you. It's the science database (Informix) which holds the 20-year archive: it's the BOINC database (MySQL) which holds only a couple of weeks of data which is time-critical and really has to fly - especially on Tuesday night / Wednesday morning when queues for kibble are forming outside the server closet.

If you really want to compartmentalise the science DB, can I suggest instead workunits

            1 -   500,000,000
  500,000,001 - 1,000,000,000
1,000,000,001 - 1,500,000,000
1,500,000,001 - 2,000,000,000
2,000,000,001 - 2,500,000,000
2,500,000,001 -
We're still coming up to a nice transition point at 3 billion (work that out in binary if you prefer), but we didn't do the early sets at even speed.

If there are over 500,000 WUs ready to send, and there are no Arecibo VLARs anywhere in sight, it's not an unreasonable expectation to get work to replace work that is returned. It's happened ever since Seti moved to BOINC, until Dec 2016 when things changed.
Given that prior to this issue occurring, even if there were a flood of Arecibo VLARs, there was never an issue getting CPU work, and it only took a few requests before a batch of GPU work would download.

If there is no data- then there's no data. And that is what we were never promised- never ending data.
But if there is data available, ready to be downloaded & processed, then it's implicit that we are able to download it to process. Being able to get it is important; particularly so if they want even more crunchers than they already have.
It's no good just splitting work if it's going to be withheld from those that want to process it.

OK, back to work fetch. My test machine has been running steadily overnight, so the values should have settled a bit. I'm seeing estimates for guppies at 1:38:00 on CPU, 09:49 on GPU - i7 and GTX 670 respectively. That's a nice factor of 10 - 98 minutes to 9.8 minutes - in the speed. I'm running 6 cores, so the CPU queue should last 1.6 times longer than the GPU queue. There are some Arecibo tasks coming through now, so figures will shift about a bit, but I'm saying roughly 0.7 days GPU, 1.2 days CPU.

For the first test, I set the cache to 0.8 days and no additional. The first fetch took me immediately to 100 GPU tasks and 83 CPU tasks, which by my current theory should allow both resources to fetch work as needed.

This was the next scheduler contact:

09/04/2018 13:54:47 | SETI@home | Sending scheduler request: To fetch work.
09/04/2018 13:54:47 | SETI@home | Reporting 1 completed tasks

09/04/2018 13:54:47 | SETI@home | [sched_op] NVIDIA GPU work request: 14460.88 seconds; 0.00 devices
09/04/2018 13:54:49 | SETI@home | Scheduler request completed: got 2 new tasks
09/04/2018 13:54:49 | SETI@home | Project requested delay of 303 seconds
09/04/2018 13:54:49 | SETI@home | [sched_op] estimated total CPU task duration: 5866 seconds
09/04/2018 13:54:49 | SETI@home | [sched_op] estimated total NVIDIA GPU task duration: 590 seconds
- one for each, which is a promising start.

The sequence seems to be continuing, with

09/04/2018 14:10:09 | SETI@home | Sending scheduler request: To fetch work.
09/04/2018 14:10:09 | SETI@home | Reporting 2 completed tasks
09/04/2018 14:10:09 | SETI@home | [sched_op] CPU work request: 2671.12 seconds; 0.00 devices
09/04/2018 14:10:09 | SETI@home | [sched_op] NVIDIA GPU work request: 14471.22 seconds; 0.00 devices
09/04/2018 14:10:11 | SETI@home | Scheduler request completed: got 2 new tasks
09/04/2018 14:10:11 | SETI@home | [sched_op] estimated total CPU task duration: 5850 seconds
09/04/2018 14:10:11 | SETI@home | [sched_op] estimated total NVIDIA GPU task duration: 590 seconds
(there were a couple in between too, but I won't bore you with every detail). The important point is that NVidia work continues to be allocated, and the NV cache is steady at 100 (CPU now 84).

I'll let that run for a while (maybe go out for a walk again), and check the logs to make sure the cache has been kept topped up. Then, the acid test - bump the CPU cache up to 100, and see if it becomes harder to get GPU work.

. . I would not anticipate any problems for this test as work seems to be flowing perfectly normally for everyone at the moment, but at least it can establish a baseline for behaviour when things are AOK. The interesting thing would be to re-run the test if/when the problem resurfaces and see if such a configuration tends to provoke or exacerbate the problem when it is happening.

Fair comment. Prod me if I don't notice problems starting up again - they never seem to trouble my GPU-only SETI crunchers (they do have CPUs too, but I do other things with them).

Edit - the Arecibo tasks I'me getting on that machine seem to be a mix of all types - VHAR, middling, and VLAR. That probably makes it a better time for testing.

A few hours after the end of the outrage should be a good time to see what's going on as that appears to be when the issue gets reported most often.
Thinking back - We all know that in the first couple of hours after the outrage there is a big splurge, however I noticed the other week that one of my crunchers was in a 24 hour(ish) back-off, the other three were of the order of 1 hour. On the basis of my admittedly very small sample of four crunchers that would suggest that 25% of crunchers would be suffering a similar delay, and so it might be that there is a substantial second splurge of demand about a day later than the main one and that may well cause some (not all) of the delays and slow work supply.

It's still working normally at the moment, reported tasks are being replaced. I'll let you know the minute reported tasks are not replaced. I'm currently running a One day cache, the CPU tasks are running about 40 tasks to the GPUs 300. My 10 year old CPU will finish the current BLCs in about 70 minutes using the Mac CPU App r3711, the GTX 1060 takes about 3 minutes, and the 1050 Ti just under 5 minutes. That equates to a completed task about every minute, meaning 5 tasks last 5 minutes, or 60 tasks an hour.

Yes, working 'by the book' here too. It worked for ~3 hours with the cache bouncing off the GPU top limit - getting replacements when there was work to report, limit report when there weren't.

So I upped the cache to 1.25 days, and immediately reached both limits at once, 200 in total. The next four RPCs were

Starting to get a bit wonky.

My machines seem to have recovered, for now.
I don't know how others are doing.

So it begins;

My machines seem to have recovered, for now.
I don't know how others are doing.


. . It started here @ about 8:55 am AEST. But after a couple of those "no tasks sent" there was a correction, then one good RPC then back to the "No tasks sent".

. . I stopped and restarted BOINC and it was fine after that and still is on Bertie, but while Donkey was OK too it only lasted until a very different episode which I posted seperately.
