LHC@home

The last ATLAS WU I received was 3 May 2022, 0:16:37 UTC

When updating LCH I get

2022-05-15 9:42:11 AM | LHC@home | Scheduler request completed: got 0 new tasks
2022-05-15 9:42:11 AM | LHC@home | No tasks sent
2022-05-15 9:42:11 AM | LHC@home | No tasks are available for ATLAS Simulation
2022-05-15 9:42:11 AM | LHC@home | No tasks are available for ATLAS (long simulation)
2022-05-15 9:42:11 AM | LHC@home | Project requested delay of 6 seconds


The server status page currently shows

ATLAS Simulation 2548 20145
ATLAS (long simulation) 0 0

And has shown both Atlas and Atlas Long as having WUs ready to send at multiple times since this started

Any hints as to what is going on here?

Do you have changed your prefs for LHC@Home?

I'm getting some ATLAS at the moment, maybe the project doesn't have enough priority?

ATLAS Long only works on Linux if you run native so, as a windows user you'll never get these.

Nope, no changes for LHC at all

I hadn't realized that about ATLAS Long, thanks I'll remove it from preferences

As for priority, LHC has the highest priority of any Project I run, and has for the last 18 months or so. Almost twice that of any other project except WCG (don't even get me started on the way their migration has been handled)

But why would Priority result in the "No tasks available" message? Isn't that more along the lines of "not highest priority"?

Did you set "Run native if available?" here:
https://lhcathome.cern.ch/lhcathome/prefs.php?subset=project

If you run Windows this must be disabled.

Thank You !

I don't remember changing that, but obviously I did

Changed that (un-selected), saved, updated project from client and got 40 WUs !! all with due dates of 2022-05-23

with a historical min run time (on this machine) of just under 2 hours and a max of 5.5 hours averaging about 3 1/2 hours, there is no way I will successfully complete 40 WUs in 7 days!

The scheduler has done this to me before :-(

anyone an idea why currently only Theory WUs are available, and no other ones ?

Yes, at the time you posted that was the only project that had work to be sent out :-) as I am not a project developer or administration person I don't know the reason why only one project had work available to be sent out. Hope this answers your question

Have A Crunching Good day

We may run out of ATLAS tasks by the end of today(10.March), but we should have some more submitted next week.

https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5447&postid=47831 and the amount of users from ATLAS did eat up the work from the other projects too.
CMS

Sorry, I thought the workflow was going to last longer, but we had a surge in usage -- perhaps another project ran out of tasks. (Ah, yes, ATLAS has run low lately.)
-dev uses the same job pool, so it runs out too.

https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4209&postid=47852

Hope ATLAS will have work again soon.

Theory have lot of Tasks, but
with 64-Core it's not easy to manage. ;-)
