I also am seeing time remaining jump to around 10 days, and it never drops I let one run for two days, and time remaining never dropped

At the same time VBOXHEADLESS is using ZERO CPU according to Resource Monitor

Yesterday, when I went into console mode, and did ALT-F2, I didn't see what I was used to seeing: a line with run time for the last event by each "processor" devoted to Atlas Instead I see one line reporting on the last event processed

and
Number of events
already finished

Event Runtimes
arithmetic mean
min/max

Estimated time left
total
uncertainty

all show N/A

I let the job run, and did receive credit for it

The job currently running exhibits the same behavior and periodically shows a rapidly scrolling mass of text, then goes back to the last event processed line

(wish I could do a screen-capture)

May or may not apply to you, but I had similar problems a while ago

At the suggestion of someone (don't remember if it was here or my ISP Help Desk), i connected my cruncher machine via copper rather than WIFI, even though I was using 802.11AC

All of my LLHC/Atlas connection problems went away

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 :-(

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"?

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?
13) Message boards : ATLAS application : credits for runtime, not for cputime ? (Message 46053)
Posted 13 Jan 2022 by keputnam
Post:
So if I run one core on a 3.5 Ghz machine, I get the same credit as someone who runs 8 cores or 10 cores on a 3.5 GHz machine?

That is totally non-comprehensible, as I'm doing MUCH less work and returning MANY fewer results

If this is indeed correct, I can allocate more cores to other projects and get the same credit in Atlas

Thanks, guys

The uninstall/re-install seems to have cured the problem

I'm about 10 minutes from completing a WU


Thinking back, I did upgrade VBox to 6.1.30 Apparently it didn't clean up the previously installed version very well

Thanks for the responses

No, I have not done any tweaking of VBox

I have uninstalled VBox, used ADAware uninstall cleanup, booted reinstalled VBox and the extension pack and rebooted again

Now waiting for the job queue to clear out to where the Scheduler requests another ATLAS job

Got a new computer recently, and for a few days, things were great

Then I started getting Computation Errors on every job I run

Last time this happened the consensus was that I had lousy internet (failure to connect to the LHC servers)



I have since upgraded my connection from 25MB to 150MB
(I can post results from several speed test sites if it will help)

Running BOINC 7.16.11
VBox 6.1.26 (+ Extension Pack)



Any assistance gratefully accepted

Already aborted the second Doesn't surprise me that there is no log file, the WUs never got any CPU time

But a third, previously downloaded and queued has started and is responding normally

Post:
The last two ATLAS WUs that I have downloaded appear to be faulty

One ran for 3 days before I noticed that while I could access the VM, ALT-F2 had no effect at all I aborted that one

The latest one has now been running for about an hour and exhibits the same behavior

Also, while BOINC reports the WU as running Resource Monitor show VBox using no CPU at all

I have re-booted and upgraded to the latest VBox version with no change


TIA for any ideas or suggestions
20) Message boards : ATLAS application : Checkpointing? (Message 43393)
Posted 22 Sep 2020 by keputnam
Post:
Can anybody tell me why a program, would take regular checkpoints, and then ignore them on restart and start from scratch? For ATLAS, BOINC manager/properties shows "time since last checkpoint," which resets every two minutes

I shut down BOINC to apply some Windows service

On restart as soon as VBox manager initialized and BOINC monitoring starts, it correctly shows a certain member of events completed

Then at some later point, it resets to zero and starts at event 1 again


???
