OpenCL, boinc, and systemd resource limits

[Arno Lehmann]

Hi all,

back to trying to get OpenCL-based boinc workloads running.

It appears that the AMD-provided OpenCL stack works to some extent under
Debian 12. However, I have some problems with OpenCL-Using boinc-managed
PrimeGrid programs.

I do get an error that seems to indicate some resource limit being involved:

Error: opencl error: CL_OUT_OF_HOST_MEMORY

when I run the boinc client through systemd.

If the boinc client is run from the shell, for example as

sudo -u boinc boinc

in its proper working directory, everything behaves correctly.

Given the circumstances I suspect some sort of limit on memory.

I just have no idea how I can diagnose this further, or even how to fix
it. An attempt with a unit file override with

[Service]
LimitMEMLOCK=1073741824
LimitMEMLOCKSoft=1073741824

was not successful.

Does anybody have an idea, or can share recommendation where to ask for
more advice? (Debian project, i.e. here because this might be
integration / packaging related, freedesktop.org for systemd, boinc
project, perhaps -- trying to get assistance at PrimeGrid did so far not
result in anything helpful.)


Thanks,

Arno

Hi all,

just to give this a reasonable conclusion... it was indeed a matter of
systemd service unit file setup, as described at

https://github.com/BOINC/boinc/issues/4948
https://www.primegrid.com/forum_thread.php?id=10048

Mail to the package maintainers with a suggestion on how this could be
improved has been sent.

Cheers,
