Points right for my system?

[iceman1992]

Did the log indicate such behavior? Might be wrong estimation, might be a checkpoint issue. I'm not sure. I've never changed the smp number mid WU (in fact, I've never changed it at all).

You might wanna post this on a new thread, though.

Hi, my CPU is now doing project 7809 and ETA was (I think it was)2.75 days. I had 1.05 days left when I turned SMP back from 2 to -1.
I've checked this morning and the ETA was 3.75 days what?! I've now put the SMP to 2 again, shut down the client and restarted waited a few minutes and the ETA is now 20 hours 46 minutes

So what happened?

Would have to see the log to be more sure of the reasons. Potential reasons include a corrupted checkpoint resulting in starting over from the beginning, or just the known issue of the TPF and ETA calculations not necessarily being accurate.

Are you still running GPU folding on your system? The SMP folding is very sensitive to synchronization between the threads running on the different cores. Your 6570 will use most of a CPU core just feeding the GPU folding process, the SMP process will be severely impacted with a setting of -1(4 cores). That would explain the ETA of over 3 days after the first change. If you coincidentally managed to corrupt the checkpoint the second restart, then the WU could start over from the beginning.

Thanks, for everybody's help! Since it's back to normally I won't worry about it.
Anyway here's (I think) is the log:

I never saw that happen in either V6 or V7 using the OS X versions of the client. It could have done that for some specific WU/core/client-version combinations, but as best as I can tell it was not a general thing. Of course reports could have been confusing a restart from the beginning due to a corrupted checkpoint that coincided with the SMP change.

Waiting "a few minutes" isn't long enough to calculate a new ETA. If the current WU is K % completed, wait until it reaches at least (K+3) or (K+4)%
