Mat,
Could you send the namelist.input file you're using, too? Who knows,
maybe something useful there?
I don't think the F is an indication of the problem. If I'm reading the
code correctly, it just indicates that the timer (not the code) is no
longer running. If you did a call to the code that prints the timing
information before calling timer_stop(), then this flag would be T instead.
