Thought this would fit in here....

Use boinctasks to prepare for a boot with one or multiple cep2 running!

Saw this in the check-in notes for version 1.64:

1.64 September 2014

New: Suspend at checkpoint. Suspends a task after a checkpoint. Checkpoint column must be active.
Fixed: Project tab, some projects show ?? in the Project and Team rank column. Added stats/stats.xml for master url to url used conversion.

This allows to suspend one/more/all tasks at checkpoint, right click selection for 'suspend at checkpoint', before a planned boot. On hyperthreaded machines the remaining tasks will one by one actually start running faster, for each thread that's is being stopped till equal or or less than maximum threads.

Think before you do this all 'ready to start' cep2 work units need to be suspended too, action to be reversed after the boot is complete.

Alternately, pick up other work with short checkpointing to fill the threads where the cep2 are being suspended, then boot for least loss and maximum utilization till right before.

Maybe there's other scenarios to use this function, but this jumped right at me.
