The total time looks to be more like 4 1/2 to 5 days now. And with three work units running, there has been no checkpoint for 1 1/2 days. So once you are in, you are in.

I have emailed Martin and received an answer. Everything at the moment is only done by him, he hopes to get a student to do some work for him. Money is still a problem here though. All work at the moment is for testing, for you to test if it works on your system(s), for him to test that it works in the back.

If you email him, do not expect an answer immediately. That's also why he hasn't put forums on, because he cannot immediately answer if people have questions or comments.

If money is a problem, this makes me wonder if anyone has talked to him about possibly funding through BitcoinUtopia...

QMC needs more work. When the BOINC scheduler switches between tasks and puts the work units on standby ("waiting to run"), then the Progress goes back to 1%. So at present not only do you need a machine that is on 24/7, but you need to ensure that QMC is the only work running, or at least that the switch between tasks interval is long enough (probably a week or more to be safe). I am sure it will be a good project eventually, but whether before global warming takes us out and eliminates the need for better batteries is questionable.

So at present not only do you need a machine that is on 24/7, but you need to ensure that QMC is the only work running, or at least that the switch between tasks interval is long enough (probably a week or more to be safe).

Or you can set "Leave applications in memory" (Leave non-GPU tasks in memory while suspended on BOINC 7.7)
This leaves all tasks that do not run on a GPU in (virtual) memory when they switch out.

Also, since a couple of years now, tasks don't switch out unless they checkpointed at least once. When an application doesn't checkpoint, it'll run the task from start to finish without break.

I always set "Leave applications in memory", but that did not help it. There was a single checkpoint on one of the three tasks (the one that had started to run again; the other 2 were still "waiting to run"), but it listed the checkpoint time as 1 1/2 hours. I get the impression that it was set when it went back to 1%, so it seems to have been set when it started to run again.

Martin answered me that he thinks crowdfunding is a great idea, but that the legal situation for it is complicated for German universities, and that he will ask his university if they allow him to do so.
