Is there something I need to do in order to enable GPU crunching?

Changing the target runtime back to 8hrs, even with the folding@home contention, will take 7-11hrs out of the running tasks and a further 7-11hrs out of the cached tasks.
14-22hrs less processing time to complete tasks will make a huge difference to whether Panic mode arises.

It can certainly be solved your way, but that gets a bit fiddly imo and doesn't resolve the confusion Rosetta runtime introduces.

Which means the the tipping point <is> a Rosetta issue after all

I'd like to comment.

I see a problem, a problem that I should not be seeing. I try to make headway to resolve it, so ask.

The result of asking each time is the same, basically, the BOINC folk tell me the problem is Folding, the Folding folk tell me it is not.

I have set no new tasks at both. I would seem to face a choice, I can support one or the other. Both are important to me.

This will solve the <entirety> of your problems, while (coincidentally) massively increasing your contribution to <all> the projects you run within your preferred settings.

I simply stated facts.

I've set no new tasks again. The current jobs have 8 hours as their runtime, but here, they are running for three times that, (4GHz i7), which is pushing my system into panic mode.

If you use Science United, you won't be able to see your BOINC credit totals on project web sites, or on sites like BOINCStats.

My stats show 973 failed tasks.

Can I delete any of these files? Is there a cleanup procedure? I'd like to complete any existing work and then pause my activity until I can get set up on a new system. I don't know if it matters, but I don't want to leave any work incomplete.

As you also say, hopefully their next job is to revalidate our older tasks from April 3rd ~22:00 UTC to April 6th ~05:20

These INVALID results are a problem with the Rosetta BETA binary.

The problem is that some of these wus are near the deadline.
It's a pity to throw away the work done.... (i don't care a lot about points, i care about science)

Have i to stop the upload?

Let's see if these work units are still credited.

Right now they are 32 core with 16gb of RAM. Which should be enough for crunching.

so even if it was necessary to employ those settings for that individual Project, those settings have gone rogue over all the other projects by now.

so while ensuring web page settings for each project are as close to your local settings as possible, it's best to ensure you use local Boinc prefs so everything's as familiar and controllable as possible.
