SixTrack has a lot of WUs at the moment. Why not crunching those until ATLAS tasks return!?
Theory has tasks, too.
since a few days, CMS seems to work fine again. So why not trying CMS :-)

hello Ivan,
once more many thanks for your thorough reply :-)

So all we can do is to keep our fingers crossed that one day CMS may work again!

Does Boinc autoupdate? Otherwise 90% of users won't know what's wrong.
I don't think that BOINC updates automatically. Once a new version is published, everyone will have to install it manually. At least that's what I guess.

And yes, most of the users won't know what's wrong all of a sudden, unless they start digging into all the forum postings at LHC and/or Rosetta :-(

There is an expired cert that walli reports so it so a new build of BOINC needs to be made with updated certs.
Why, though, do other projects within BOINC work without problems, like GPUGRID and WCG ?

same problem here, with LHC and Rosetta. GPUGRID and WCG are okay.

When opening the file ca-bundle.crt it shows a certificate valid from 1.9.1998 - 28.1.2028.
Besides, line 4 says "Certificate data from Mozilla as of: Fri Jan 26 21:30:21 2018 GMT"

Well, I think Jim1348 was perfectly right when saying:
Erich,
I just did one. It failed as usual. No need to waste your time.
So I abandon CMS for now; it's a pitty, but what can we do if they are not able to repair it after so many months :-(

so, I just got a task finished after almost 10 hours with "unknown error code" - how nice:

I really don't understand why CMS tasks are offered for download, if in reality they are junk :-(

Post:
well, also this morning, I had a few tasks that failed after about 20 Minuten, but also a few ones which have been running four hours now.

So, all in all, CMS still does not seem to function the way it's supposed to. Really too bad.
After it has not been working well for such long time now, I think it would make sense to either repair it as soon as possible, or to delete it from the subprojects list.

I've got two successful ones now. I guess the failures from yesterday evening were due to these server problems described by Nils in the News Thread.

Post:
Due to a failure of a database storage system, a number of database services at CERN failed on Wednesday afternoon. The LHC@home servers were affected as well, as the BOINC database was unavailable and requests timed out.
Sorry for the trouble and happy crunching!

Nils, the problem still persists, though. Here, neither ATLAS nor CMS tasks are working.
Any idea when it will be solved?

13) Message boards : ATLAS application : three 1-core tasks possible with 16GB RAM? (Message 42612)
Posted 13 days ago by Erich56
Post:
I followed the instructions given above (setting the value, to make is simple, to straight 4000000000.00000) and it works with 3 tasks simultaneously - all 3 of them startet right away.
At this point, after about 1 1/2 hours, the total RAM usage is shown as 14.46GB. So I'll see how it develops during the following night (if I am unlucky, it will go up more and eventually crash; if I am lucky, the tasks will be finished tomorrow morning).

Of course, the procedure of changing the rsc_memory_bound value is rather tedious :-(

Only hanky panky helps here:
Load a number of Atlas-tasks and don't let start them. Shutdown BOINC client and edit client_state.xml
Change <rsc_memory_bound>xxxxxxxxxxxxxx</rsc_memory_bound> in the ATLAS workunits to a lower number.
okay, thanks for the hint. While 2 tasks are currently running (and I don't want to kill them) I took a look at the client_state.xml. It shows the following value:

<rsc_memory_bound>5976883200.000000</rsc_memory_bound>

I guess, for future tasks, changing this value to about 4 GB should work - do you people agree?

thanks, Crystal Pellet, for your reply.

You are right, max CPUs was set higher than 1 in the preferences.
I will correct this now and see what happens after new tasks will be downloaded with this new setting.

BTW, can I see somewhere how much RAM BOINC is reserving for a given task? Obviously, that must be different (i.e. higher) to the 3.900MB that I have set in the app_config.xml.

EDIT: I just changed the preferences to # of tasks: 3, and # of cores: 1
And by doing this, I seem to be caught in the known trap - this setting would let me download only 1 task, not 3 :-(

Did anyone ever succeed in running three 1-core tasks on a system with 16GB RAM?
I set my app_config.xml accordingly, but only 2 tasks are running concurrently.

(I know that I could set the system to run one 3-core task. I was just curious)

20) Message boards : Theory Application : VM Button missing in BOINC Manager after Windows Update (Message 42252)
Posted 22 Apr 2020 by Erich56
Post:
Within the past few days, I noticed several other cases, also on other machines, where the "VM Console" button was missing. I guess in 1 out of 10 tasks or so.
This has never before been the case, only since the latest Windows Update. Very strange.
