On another note, I just got back from the airport and sat down at the computer my 780 is mining on and noticed that things were behaving a little funky. Turns out the SSD was full and my output log contained 77GB worth of cuda errors. (I've been running cudaminer in a forked bash shell and redirecting stdout to a log). Thank goodness for trim.
better error handling and recovery is on my TODO list.
CUDA behaves a bit funny once a serious error occured. I will have to do some research on how to reset the driver.
would Linux offer a feature to keep rolling logs that are automatically getting trimmed at the top, e.g. to a fixed file size or to a fixed number of lines?
