Help! I had a project up to 92% when it disappeared on me after I unpaused my client. Then I found a new project at 0% in it's place. I am not sure what is going on here. Can someone please advise what happened and how I can prevent it from happening again? Thank you. Here is the log file:
It looks like the same work unit you had completed 92% on. The log does not show it starting over yet though, so it isn't clear if you lost the last 5 days or not. Though if FAHControl shows a 0% progress bar, then you most likely lost it :/
The unstable machine error is something you should look into. Your GPU may be getting too hot
FahCore_11 is trying to restart but it has detected that the simulated time T in the checkpoint doesn't match what it should be. You can't resume work from a checkpoint which contain inconsistencies so the WU was restarted. If it took you 5 days to get to this point, then the answer is Yes, you lost 5 days.
There might be a clue to what happened at the end of the previous log (whenever the WU was paused) but there may not be. In the past I had trouble pausing/resuming work with FahCore_11 and if it's a bug, it's not likely to be updated. Current development work seems to be going into FahCores which are used by newer GPUs.
Thank you everyone. Yes it did start over after this error so I did lose the 5 days of folding. Oh well, back to the drawing board.
I never had this happen before. Is pausing a bad idea? I do that a lot since sometimes I need to use my computer and folding consumes a lot of performance.
I don't see your hardware profile so I'd have to guess what can be done about "...folding consumes a lot of performance." but maybe there's something that can be done about that if we knew more. In many cases, fah can be convinced to yield performance when you want to run something else without completely pausing the WUs. Do you leave the CPU/SMP slot processing and just pause the GPU or the other way around?

I just hit the pause button at the top of the client and that kills everything. Both cores shut down and the GPU.
Yes, but you can also Pause individual slots. Right click on them. I do suggest you experiment with pausing only the GPU or only the SMP slot (assuming you have both running) and then we can work on how to get your foreground performance high enough to make you happy and still allows FAH to continue to process at a slower rate when you're using the computer -- or just keep using pause if you don't want to experiment with FAH on your system.
Btw, the right-click-on-the-slot thing only works in Advanced and Expert modes. Use the drop-down menu in the upper right-hand corner to switch modes.
F@h is now the top computing platform on the planet and nothing unites people like a dedicated fight against a common enemy. This virus affects all of us. Lets end it together.

Interesting. When I shut down the SMP core, my CPU does not drop to 0% performance. It stays at 50%. Does FAH still is being reported as using 50% of my CPU power with only the GPU running. It looks like that only one core of my core 2 duo is shut down that way. Does that seem right?
Also, I get an error box when I shut down the GPU by right clicking. It says click OK to terminate the program. FAH does not close when I click OK and I lose no folding when i restart the GPU. But it does look a bit scary to see an error message.
No HW profile, means I'm just guessing. I'm assuming that you have an AMD GPU and a dual-core processor. AMD GPU's typically need a full CPU core in addition to the GPU. At that point you will only have a single core for the SMP slot, so I suggest that you go uniprocessor + GPU or SMP without the GPU whichever gives you the highest PPD (points per day). If my read of your hardware is incorrect then feel free to disregard because my suggestion only really applies for that set of HW assumptions.
The SMP or Uniprocessor slots should not affect performance of your machine when it is on. The Windows priority system will execute the application in preference to folding because the application will invariably have a higher priority since folding is very low.
GPU folding however has no method of getting out of the way, so it will cause problems if you want to run something else. So if you are having performance issues, suspend the GPU slot as your first choice and see if that helps.

Thank you. I understand the issues with the GPU now.
