@Trotador, do you think so? Maybe the only difference is that the server was finally done validating its backlog of almost 80,000 camb_legacy WUs, and now both the processor load from the validator and the database size should have gone down.

If there was a server upgrade, it was performed without server downtime. Hence I doubt it.

Besides, looking up computer results lists, let alone user results lists, at the Cosmo web server is still an extremely slow undertaking.

As a followup:
Evidently, Marius gave the legacy validator a kick on October 5.



It worked through its backlog of WUs waiting for validation and finished it at October 10, ~22:00 UTC.

any way around?

Two even.

a) You can run boinccmd --project_attach "http://www.cosmologyathome.org/" authenticator in a terminal. authenticator is a long hexadecimal string, also known as acount key. It is the first key shown at weak_auth.php when you are logged in here. (At your user account page, go to "Acoount keys - View".)

b) You can copy the file account_www.cosmologyathome.org.xml from the BOINC data directory of a host which is already attached to Cosmo to the BOINC data directory of the host that you whish to attach. Then restart this client.

While I had difficulties to receive tasks during the last few days, I nevertheless used to get quite a few, as my RAC indicates.

But I have not received a single tasks anymore since today, 10:30:24 UTC. (Talking about camb_boinc2docker only; I have camb_legacy checked off.)

I looked at the top 100 hosts. None of them has received tasks after 10:30:24 UTC either; neither camb_boinc2docker nor camb_legacy. With the following exceptions: Hosts 356704, 330383, 349863, 348148, 338259 received 7 tasks together, all of which are resends of previously failed tasks, not newly generated WUs.

server_status.php claims that camb_boinc2docker_work_generator and camb_legacy_work_generator are both running (status from 10 Oct 2018, 17:49:32 UTC), but there are clearly no new WUs.

Since September 28, the camb_legacy validator is down again.
Meanwhile, the camb_kegacy work generator keeps generating...



(I am not affected myself, as I run camb_boinc2docker only.)

Edit,
BTW, the drop in PPD in Gridcoin's stats shows that the Gridcoin miners are on auto-pilot, and run 95 % camb_legacy : 5 % camb_boinc2docker. (Going by credit; going by CPU time it is an even lower percentage of camb_boinc2docker.)

Do you mean the program directory, or the data directory?

You don't need to CD into the program directory if you either specify the full path to the exe like in my example, or add the program directory to the PATH environment variable.

You don't need to CD into the data directory if it is the default BOINC data directory path (C:\ProgramData\BOINC\) or if you add the --host and --passwd options to boinccmd call. The latter is applicable if your boinc client is configured for restricted remote control.

(A brief and not very readable info on control access: https://boinc.berkeley.edu/wiki/Controlling_BOINC_remotely)

M wrote:
but still a GUI fix would be nice for the sake of convenience.

If you need the snooze function with just one particular timeout, you can put the command with all its parameters into a *.BAT file or simply into a shortcut.

For a selection of several often needed timeouts, you could create a subdirectory somewhere, e.g. in the Programs folder of Windows' start menu*, which you populate with several shortcuts for different timeouts; say 1.25 h, 1.5 h, 1.75 h, and so on.

PS:
If you run your movie player on the same PC as the boinc client, you could add the movie player into the dialogue "Options" / "Exclusive applications..." of boincmgr's advanced view. Then, the boinc client will always suspend computation as long as the movie player runs.

This can be done in DOS/Windows' basic CMD shell with just a single command:

    "C:\Program Files\BOINC\boinccmd" --set_run_mode never 3600


This is for exactly 1 hour suspension of boinc's CPU activity. Replace 3600 as desired.
More info: https://boinc.berkeley.edu/wiki/Boinccmd_tool

If you want to issue two specific boinccmd commands with a defined gap between them, it can be done in CMD or as a *.BAT file too:


    "C:\Program Files\BOINC\boinccmd" your_first_command
    TIMEOUT /T 3600
    "C:\Program Files\BOINC\boinccmd" your_second_command


PS,
you'd perform this without shutting the boinc client down. The client simply suspends and resumes the science application on command.

Some graphs from stats3.free-dc.org:

Daily points added:

This dramatic increase in PPD is certainly to be attributed to the camb_legacy validator put back into operation, and only to a small part to the sprint activity. The validator began its work on Friday, July 20, 12:48 UTC, but stats-free-dc picked it up first with their Saturday update.

Daily teams added:

Nothing unusual to see here.

Daily users added:

Again, the effects of the camb_legacy validator operating again is dwarfing any effect that the sprint may have had. free-dc's Saturday stats update was the first to catch points of validated work from many users who joined during the 4 weeks during which the validator was off.

Daily hosts added:

Here we may see a certain effect of the sprint announcement on July 18 22:00 UTC, and then on Saturday again a huge effect of the validator fix. Most of these hosts were surely added during the past 4 weeks.

Marius,

FYI, the sprint is over since 14 hours now.
The server status page currently shows:

application ....................... unsent .... in progress
----------------------------------------------------------------
camb_legacy .................. 0 .............. 52906
camb_boinc2docker ....... 0 .............. 9137

0 unsent looks correct to me because no tasks are received by my clients now. (I didn't try hard though.)

But 62043 in progress is likely incorrect. My own tasks list shows 2 tasks in progress which the hosts reported as complete mid Friday, and 11 tasks which they reported complete mid Sunday. The clients must have received proper scheduler replies that the reports were taken by the server, otherwise I would still see these tasks locally, of course.

I don't worry about the credit for these 13 tasks. I am only mentioning it just in case there is something odd with the database in general.

Is the project in need of hardware donations?

We need to send equipment (packed up safe for transport) to Marius and his fellow cosmologists until they finally figure out what's been up with all the as yet unaccounted matter in this universe.

Marius, thank you.

I ran camb_legacy for half a day on Thursday until I had time to add Virtualbox on hosts which didn't have it before. Current status of my camb_legacy results: 90 % valid, 10 % pending validation (not counting tasks which I aborted once I had vbox sorted out).

PS,
I don't particularly like to have vbox's kernel modules on my machines due to their bad track record WRT kernel stability in the past (works for me currently though). And I do not like the footprint and subpar BOINC integration of vboxwrapper based DC applications. But I acknowledge that it may be a help to application development, and also recognize that results from camb_boinc2docker are of more value to the C@H project now.

PS,
perhaps the camb_boinc2docker work generator shouldn't even work faster than it does. Given that the tasks have a run time of just a few minutes but produce results files that are 2.6 MB big, I wonder if Cosmology@Home's internet connection bandwidth is another limit which prevents a higher production rate here.

(In other words, camb_boinc2docker tasks are not very effective from the Distributed Computing point of view, because of too short of a run time and too large network transfers.)

@scole of TSBT, camb_boinc2dockers can be bunkered.

But (a), certainly not many did bunker camb_boinc2dockers, and not much of it, and (b) whatever bunkering activity was going on on Thursday, it didn't have any bearing on the further decline of work availability that we saw over the course of Friday, especially towards Friday night.

Contributors' computing capacity during this sprint simply exceeds the pace of Cosmology@Home's work generator, by far. (My initial predictions in this thread that work would become available again some time after the start of the sprint were, unfortunately, far off.)

A possible fix which worked for me was to shut down the client, correct all corrupted download URLs in client_state.xml using a text editor or a tool like sed, then start the client again.

As far as I can tell, the Cosmology@Home server is generating enough work for everyone who wants to join the sprint.

Of course those who are impatient may be dissatisfied with the pace at which new work is generated. So, be patient. :-)

We are now 7+ hours into the sprint, and unfortunately, the rate of work generation is not just low, it is too low.

There is more participation than available work. :-/

Also by "equal ground" being they all get 100 Gallons of Full not some getting 100 Gallons and some only 50 Gallons of Full.

There is no inequality. Everybody has the same good luck or bad luck getting tasks.

There were hours earlier today, during which about 75 % of the requests for work would get you work. Right now, only a few hours before the actual start of the sprint, unfortunately only about 10 % of all requests for work get you work.

It will get better again when the initial rush is over. Nothing out of the ordinary.
