I just noticed that checkpointing might not work correctly.
Had a WU on my C2D lappy running and had to shutdown/restart BOINC.
It still showed the CPU time of 1.5 hours then but the progress bar started from zero.
Do the WUs really start from scratch when restarting BOINC?


EDIT BOINC version 6.6.20 under Win XP 64-Bit

Any comment?
I can't crunch such long WUs without knowing if checkpoint is working or not... :-(

3 hours and you need a response? Someone needs to learn a little patience. Please go over the MW board and make a post to the admin. You will wait weeks without hearing anything.

To answer your question, I was going to spend the day retesting the checkpointing, but that will have to wait since I now have to spend the day securing the application due to unauthorized versions being run.

In the mean time, you can always turn on the "leave app in memory" as it takes less than 2MB RAM. I know that's not the answer you wanted to hear, but it is the best I can do for now.
