Development for LHC@home

It's a month that my windows pc are running docker app without big problems.
So, what's the next steps? Checkpoint? Gpu?? Release it in production??

Well done, guys!

Checkpoint? Gpu?? Release it in production??

Uh, I missed that the boinc admins are working on it...

We have to wait until the BOINC project releases the BOINC server.

I don't understand.
In "traditional" boinc app, the checkpoint must be implemented by the developers of the app.
With the new "docker app" the checkpoint is done by boinc developers or by the app developers?

erreur theory docker

bonjour,quelqu'un peut m'expliquer ou est le probleme?

hello, can someone explain to me where is the problem?

The log tells you what's wrong:
"The cgroupv2 manager is set to systemd but there is no systemd user session available".

The podman manual tells you to set "cgroup-manager=cgroupfs" in containers.conf instead:
https://docs.podman.io/en/stable/markdown/podman.1.html#cgroup-manager-manager

Please make yourself familiar with the podman manual.
