Thank you for your response!
--edit-- The 'test' was the trick!! I just downloaded 7 WU. YAY!
-- end edit--
I had not checked "test" . I just changed project preferences and enabled 'test'

my Boinc Logs says:

i wrote a shell script to update LHC every 4 to 6 minutes. Will keep you posted on the outcome.

A question for you:
are you using a 'standard' BOINC -LHC install?

FYI, I am running

3) Message boards : ATLAS application : Ubuntu 20.04 support?
Message 52425
Posted 1 Oct 2025 by Profilejay
Greetings!!
I am a newbie and was ecstatic when I got 2 WUs to run to completion last night.
( Yes, there were some failed attempts while setting up. )

At this time, I am only running on a laptop, but, want to move to a larger, faster machine once I get the heatsink installed.

I'm using Linux Mint 22.2, BOINC client version 7.24.1, with 32GB of memory, set LHC profile to use 4 of 8 cores,
and
/etc/cvmfs/default.local
reads:

CVMFS_REPOSITORIES=atlas.cern.ch,atlas-condb.cern.ch,grid.cern.ch
CVMFS_CLIENT_PROFILE=single
CVMFS_HTTP_PROXY=DIRECT
CVMFS_USE_CDN=yes



I copied the CDN=yes from https://cvmfs.readthedocs.io/en/stable/cpt-quickstart.html .
I read your post: https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5630&postid=44804,

I would like some help understanding openhtc.io and cloudflare. Are they optional? Already built-in by the set-up?
And , when I add a two more local PCs, I wonder if I need to set up - like a cloudflare account.


THANK YOU in Advance,

with an old laptop (1.9 GHz Intel), I got my first Xtrack WU , (Yay)
So far, 3 have completed
A) 2 hours 18 minutes
B) 2 hours 54 minutes and
C) 2 hours 54 minutes and a bit.

These times are faster than the estimated 15 hour remaining time.time.

5 other WU are still processing and 1 has not started yet.

I agree.
Denis@Home use such a scheme to improve effective WU crunching.

Message 46388
Posted 28 Feb 2022 by Profilejay
Greetings.
I can not find a requirement webpage for the LHC requirements.
I did
- set BIOS VM setting
- reinstall BOINC with VBOX
- successfully run an Atlas WU.
But since I could not find out what the wu did, I cancelled - and restarted.
This time, I will try sixtrack - without VBOX.
But I see:

So, is VBOX really required for sixtrack WUs?

Another weird thing....

I looked at the co-pilots of the WU that went - over-limit for me.

of the 30, I only saw one wu that was sent to a client that did not fail.

I wonder why it didn't have the problem..

Message 26772
Posted 3 Oct 2014 by Profilejay
Greetings,

Also getting a task result of "Maximum disk usage exceeded".

Is there a patch we can make to allow more disk space?
Or, is this embedded in the task code??

I'm getting these around 15 to 20 minutes into the tasks.

Thanks,
Jay

-- edit--

PS
The disk limit does not seem to be related to the BOINC disk resource limit that the user sets up.
( I have >70 GB allocated for BOINC, only 1.7 used.
Atlas had used up a large pre-allocated disk space...)

About the same here.

64 bit Vista runs to completion. (about 1,200 seconds)
32 bit XP, well, still In progress.. (Assume about 3,000 seconds)

Yes, it a slower pc - but should it take nearly 5 times as long as a cpu that is twice as fast?
Is the floating processors that slower?

yes, it has little memory - but I monitored swapping and there was none going on.
It is an HP mini with an ssd drive - there was sufficient drive space as well.

All this said. The other client finished in 32,950. so the WU should be OK.

I have processed other WU on this PC http://lhcathomeclassic.cern.ch/sixtrack/results.php?hostid=10310501 - anther wu took 166,684.99 seconds - over 46 hours.


Main question:
Could an LHCatHome preference be made to avoid long WU??

Thank you all...

Jay

edit - yes, the '6' in the wu name means it takes lots of loops.
But can I avoid these? - end_edit

Here is a sample of results on a wu

Or, should I ask for more and process out as errors?

Hello Eric!

First of all, thank you for the status report.
It gave an in-depth sight of the trials and tribulations of the lhc@home effort.

Coming out with exact floating point results on different platforms is amazing.

[begin slightly-off-topic]
I share your concern about getting quick results back to the physicists.
I'm running beta Seti@home and they have a deadline for GPU of about 6 weeks.
IMHOP, this is a waste of database resources that follow getting the results from different clients to validate. I applaud lhc@home use of a shorter deadline.
I would suggest an even shorter deadline, but doing that can put a limit on the performance of the volunteer's machine.
[/begin slightly-off-topic]

About the disk space.
Is starting a pay-pal donation account within reason?
Or is showing due diligence too mind-boggling difficult?


Thanks again for the report..

Hi,
I wrote the first message because all that showed up (that I could see)
was the -161 error code during file transfer (which says the program crashed during upload).

Apparently another round of tests were released.
So far they are passing

http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=10011467
through
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=10011484

so this is now, probably, a non-issue.
