Meantime, if the project update the wrapper is not a bad idea: now they are using 26203 (3 years old) and the newest is 26207 (December 2023)
Since 26204 there is the multi-attach functionality

I'll try to contact someone by Twitter/X o by mail....

Thanks a lot.

Maybe I should also add that, since the rosetta python app runs in Virtualbox, it appears that BOINC does not have full control over the RAM usage?

Due to the immense disk space and RAM requirements, I would like to ask for an increase of the deadlines of the Virtualbox-using rosetta python tasks.
Given the deadline of currently 3 days with a single task taking about 6,5 hrs on an i5-2500K processor, I'd like to suggest a moderate increase in the return deadline for these specific WUs.
Do you think this would be possible?

And 1572864 MB of RAM

This way it won't use 11 gb of hdd for every core.

It copies 11 gb vdi to slot directory, so it still doesn't use multiattach, unlike lhc@home.

Can you test multiattach images?
