Development for LHC@home

It seems there are 200 theory tasks but I won't get any, there is no breakdown for theory/native theory on the server status page. Note that I have no VB (nor capacity to have it) on that small hosted VM.

But I just got 2 native atlas tasks instead, when server status says there are only 3 (only) on-going Atlas (no breakdown neither).

Have to wait, I guess.

Well I got one today and exact same error, it didn't work :(

It makes no sense to investigate that error with the Theory native version currently on the -dev server.

As already mentioned a new version will be send out soon.
If your errors persist it makes sense to investigate against the new version.

I was not aware and I agree, of course, especially if the "soon" is really real :)

The version that I mean is out since this afternoon:
https://lhcathomedev.cern.ch/lhcathome-dev/forum_thread.php?id=633

1. step
Download and run the script Laurence has set a link to.

2. step
try to get a task (suggest only a few ones first)

3. step
upload the results even in case of an error

I'm sorry I have no idea how to get that script (and then run it) in command line from the no-GUI debian VM I'm using for LHCdev :/


edit : I actually have another debian on a VM on my iMac that I have never used for LHC, there (I think) that I could run that script now, and attached it to LHCdev and I got native tasks (for both theory and atlas) but (obviously) all is failing because I never ran all the stuff that needs (install applications, setup... ) to be done to run the native applications... (I never intended to do it on that machine)

If you explain me how to run the script on my no-GUI VM (that one is not a VM in my mac, it is a small hosted machine on a cloud provider) I'll give it a try

In the "working debian VM" (the one I was always using for LHCdev) I got some native tasks again (Theory Simulation v5.90 (native_theory)
x86_64-pc-linux-gnu, is this the new version that is being discussed ?), the error has changed, I assume this is because I could not run that script ?

Thinking about it (more) I think I have a way to run that script on the no-GUI VM, but I won't be able to try today.

Your logfiles show a couple of entries that will finally lead to a system not being able to use the new functions.

Most important:
It is a must to have at least sudo version 1.9.10 installed since this is the first version that supports regular expressions in sudoer files.
Your system reports:

04:04:45 CEST +02:00 2023-09-07: cranky-0.1.0: [INFO] Found Sudo version 1.8.27.

Without that cranky will definitely switch back to legacy mode.

Runc may still be an issue but it needs to be tested again with the next cranky version.


Since meanwhile some other minor issues have been found another new version is in preparation.
You may check this forum for notifications about when it is available.

CentOS9-VM.
In the folder of the slot is a file output.tgz NOT deleted, after theTask is finished,
so, the next Task create a new folder in slots, for the new Task.
After 100 Tasks, Theory-native stopping running Tasks,
After deleting this 100 folders, new native-Tasks running again.
CentOS7-VM is correct.
