I have a Collatz task running, which uses 0.02 CPU and 1.00 GPU.

If I will click "Resume" when it was a few time since the start - a few minutes,
it will revert to 0.000% and start the task from the beginning.

If I will click "Resume" when it was more time since the start,
it will mark the task as "Completed" and send to Collatz server.
Of course, it will get status "Completed, validation inconclusive" after validation;
because the task was failed.

The only solution at the moment is NOT to use the Resume button for this task.

My system: Macbook Pro 15" 2011 (CPU i7-2720QM + GPU HD 6750M)
Mac OS X Lion 10.7.2 + AMD Radeon HD 6750M + Boinc 7.0.7

I am noticing the same behavior on my iMac.

As mentioned in this thread http://boinc.thesonntags.com/collatz/forum_thread.php?id=823 checkpointing has not been fully tested yet.

I guess it has now. Unfortunately, the test failed. :-(

Time to debug....

Sure, if you exclude the performance aspect. :-(

I hope the performance would be improved at the next releases.

Nikolay - was the performance improved?

I think I have the same system as you.
Collatz WUs run in 3h45m, minis in 27m
