41) Message boards : Number crunching : 10 Year old Threadripper? (Message 48333)
Posted 2 Aug 2023 by Toby Broom
Post:
To migrate an old computer to a new one you copy the files over, each computer has a GUID as long as this is the same then it stays the same.

I have for example this one:
https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=9930007

I just upgraded to this 13th Gen CPU. I switched OS's Win, Linux, OSX

Sometime I messed it up and didn't copy the files correctly and it made a new number like this one:

https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10831474

In theroy I assume you could get the GUID from here:

https://stats.free-dc.org/stats.php?page=hostbycpid&cpid=b8d05e1ba92dd93637729e85dcc78930

the CPID is the unique number part, this could be used craft custom xml but I never felt I knew how to do.

e.g.
client_state>
<host_info>
    <timezone>7200</timezone>
    <domain_name>Desktop</domain_name>

Posted 19 Jun 2023 by Toby Broom
Post:
For a result to be considered vaild then the cohort needs to come to an agreement, so if someone else is not done with there WU then neither will get credit.

e.g.

https://lhcathome.cern.ch/lhcathome/workunit.php?wuid=212365029

Now that all WU's are out then they should not be long, so there must be someone else working your pending ones.

it rare that the validator gets backloged on the server side.

Yes, however, they always come in waves since I imagine that the scientist need to look at the results from one batch to design the next batch, is not designed to give consistent work like the other projects.

Thanks, will leave them then, they are all high prio since BOINC is confused. Single core has makes more points it seems from my previous investigations.

Posted 19 May 2023 by Toby Broom
Post:
I've seen this before, in that the server just seems to send all of one sub-project, to me it seems to be a server side thing.

I personally came to the conclusion that the scientist or administators have the balance of work the way they want it and I should not try to make an even split between the sub-projects.
50) Message boards : CMS Application : Exit status 12 (Message 48112)
Posted 17 May 2023 by Toby Broom
Post:
Yes was that host.

On linux the home dir for the boinc user is /var/lib/boinc-client/ so in here.

If it messes up again I can give that ago,

i think that the reason to abort them all was when I tried to run the virtualbox gui as the boinc user, there there a crash report message for Virtualbox something to do with qt.

_usr_lib_virtualbox_VirtualBox.128.crash

After this nothing would run so I just quit them all and rebooted.

When I open the VirtualBox GUI theren is no media, since it doesn't run under my account it runs under the boinc account.

I cannot su into boinc as there is no real account for boinc.

I did rm * on all the stuff in .config/VirtualBox, now its back after aborting all the tasks and rebooting.

How can I fix this?

Command:
VBoxManage -q closemedium "/var/lib/boinc-client/projects/lhcathome.cern.ch_lhcathome/CMS_2022_09_07_prod.vdi"
Output:
VBoxManage: error: Cannot close medium '/var/lib/boinc-client/projects/lhcathome.cern.ch_lhcathome/CMS_2022_09_07_prod.vdi' because it has 2 child media
VBoxManage: error: Details: code VBOX_E_OBJECT_IN_USE (0x80bb000c), component MediumWrap, interface IMedium, callee nsISupports
VBoxManage: error: Context: "Close()" at line 1878 of file VBoxManageDisk.cpp

I tiried to run the command manually and with sudo but they kept comming up, I try to rebot and see what happens.

Post:
If you set Max # jobs &/or Max # CPUs to anything other than No limt then it could be there is a cap.

Given how long the tasks take I'm not sure why you need such a buffer of work, I have 0.25 day of work and have 70 on my computer, 36 running and 34 buffer

Its was confimed in the presentation at BOINC 2023 conf, there will be a delay vs the CPU since there is some work to do, lots of work being done inside CERN uses GPU for XTrak

Posted 15 Mar 2023 by Toby Broom
Post:
My total all time is 2% and last 30 d is also 2%.

My observation is though these stuck ones don't get any work so overtime you just end up doing no work as they all gave up trying to get work.

Post:
I just abort them, as discussed before, if you reboot the VM it can come back but once you have the error its time out getting a WU from the backend.

I does on LINUX also just not as much I would say.

Post:
I tested it out and it doesn't work as expected. Either the webpage is the wrong one or it never loads up.

I can use the screenshot function then OCR the picture to see what the console output but this is sub-optimal I would say.

There is some files in:

slots\n\boinc_WUName\Logs


they aren't the same as whats show in the Fn-F2 screens of the VM though

Did anyone work out a way to read the VM console output from the host operating system?

I looked thouhg the files in the slots directory but there isn't anything there.

Posted 17 Nov 2022 by Toby Broom
Post:
I do all tasks with 1 CPU but atlas uses a lot of RAM due issue with how it works on windows.

So with 32 GB of ram you can only run 3 WUs, as CP said you are probably better off to run a few more CPU / WU
