I was not aware that checkpointing was determined by "my settings" ???
Where would I check that? Taking a wild guess .... Write To disk at most every 1 second, switch between applications every 30 minutes.
EDIT: I aborted that previous task in the image I supplied so it never finished, but here's another one that I decided to let run, just to give it a chance ...
2nd EDIT: I run all my BOINC slots in a RAM DRIVE, would that have something to do with it?
