Timered Checkpoint Triggered


Should I be worried about this?

This system has not been used at all today except folding.
The only other time I've seen this was after playing games.


Arguments: -advmethods -forcesse -verbosity 9

Warning:
By using the -forceSSE flag, you are overriding program
safeguards that monitor the stability of SSE
instructions on your system. If you did not intend
to do this, please restart the program without
-forceSSE. If work units are not completing fully,
then please discontinue use of the flag.

You don't need to worry about that. It just means that the frames are taking long enough to be saved by f@h. That just means that in theory, if the power went out or something like that, your unit would pick up where the last save point is instead of starting back at 0 frames.

I'm not sure what the checksums not matching is. Could be a corrupt f@h folder, but maybe not. Somebody more knowledgable than myself should be along shortly to clear that up for you

Checksums don't match is the warning that during prior shutdown the work was somehow currupted and the WU restarts from the beginning. This is normally seen during abrupt unnormal shutdowns such as power failure or after a lockup reboot. I have never personally seen the timered statement being displayed after each completed frame. Hopefully it indicates that each completed frame is being saved to the hard drive so checkpoints are being established and an improper shutdown won't make you have to start over. Crash it and restart and let us know what happened (j/k).

You are using the -forcesse argument which indicates to me that you are using an AMD processor. I bring this up because usually during a checksum not match restart, Extra Sse Boost will not be turned on and you have to restart to get it turned on. This did not happen in your case. I would be very interested to know how that WU completes. Please keep us posted.

After a reboot (not a crash tho ) It didn't give me the checksum "error" this time. Its at frame 71 now at about 15 min a frame and still "triggered" after every frame. I'll check again after work to make sure every thing finished ok and post results here.

Thanks for your input folks.

You have the -verbosity 9 flag running, which yeilds the MOST info in the logs, most likely JetMech does not have this flag and that is why he does not see the timered checkpoint. The timered checkpoint is like a save... every so often (it can be set from 1 min to 30 mins, i think default is 15mins) it does this, again you only see it because you have the -verbosity 9 flag on, without that flag you would not see the checkpoints. The checksums don't match could be a variety of things... just keep and eye on it. How is your OC?

Just got home and every thing looks fine.

Its just weird cause the next unit I recieved has been running for over 45 min. and hasn't received the "timered checkpoint" even once yet.

The checkpoint will only go if the current frame goes over that time (15 minutes).

You're right Nik. I've never used the verbosity flag 9 (getting kind of lazy about keeping up with all these improvements to the process). What I do know is that I have never successfully recovered a from crash with F@H4. Sounds like I need to check my setup.
