Is it possible, that in the future releases the client will save the progress (and the achievement) of the calculations (e.g. in every ten minutes)?
Because it\'s a bit annoying, that my pc worked on session 368 (6-hours WU on my pc), but I had to restart it after four hours and the client began from 0.00% and 6-hours again... :( And it wasn\'t the first time.

csega, I notice you\'re using XP. I find that if I hibernate instead of shutting down, it restarts from where it was before.

He said he had to restart, not to shut down...

and btw.: If you hibernate instead of going into standby blender will restart the workunit from beginning.
The difference is: Hibernate saves memory to disk and after powering up again reloads it. Which is not yet supported by burp.
With Standby no problem.

Actually that\'s not quite right. The new client supports hibernation quite fine. Hibernation is really a suspend-to-memory where the memory is then written to disk by the OS. What the BURP client does not support is the suspend-to-disk feature of BOINC (aka. checkpointing).

If Blender does in fact restart upon hibernation then that\'s a bug. Please confirm whether this is the case.

Janus, you were right! I miss in this client the checkpointing! I just couldn\'t phrasing it normally... Sorry. (In the clients before, that was not a big problem, because to finish one WU took ten-twentys minutes. At least on my pc. But now, there are six-hours WUs...)

So I know, that in this version the checkpointing is not supported. And in the future releases?

(Till then, I will hibernate my system. ;))

I\'ve found this to be quite failsafe:

1. Make sure that you have enabled \"Leave in memory when preempted\" in your BOINC general preferences
2. Suspend all tasks in BOINC manager (I\'m doing this one-by-one - \"ready to start\" tasks first! -, but I suppose \"Suspend\" in the BOINC mgr menu will work just as well)
3. Hibernate Windows
