It sounds like there isn't an output.nc to look at at all.<br>

<pre wrap="">Hi, Mat.
I'd agree with Xylar's assessment that the F is probably not an
indication of anything wrong -- rather, just indicating that none
of the timers were active at the point where their times were
printed.
I wonder whether there could be some problem with the mesh
decomposition file, graph.info.part.64, that is causing cells to
not be assigned to any MPI task? Have you checked whether the
fields in the output.nc file are garbage or not -- or perhaps
whether all time periods look identical to the initial state?

<pre wrap="">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.

<pre wrap="">Hi Michael and Todd--
i've been trying to run the 1/10 dipole POP grid in the sw
configuration and am getting something i haven't seen before. all
appears normal--all mpi process are going, etc. the *.err files say
it is looping over timesteps, though clearly nothing is being done
(happening too fast). <font color="#ff0000">there's no output.nc file.</font> here are examples
of the log.0000.* files (running on 64 cores):
<a class="moz-txt-link-abbreviated" href="mailto:mm@cy-2.lanl.gov">mm@cy-2.lanl.gov</a> {10}% tail log.0000.err
Doing timestep 11
Doing timestep 12
Doing timestep 13
Doing timestep 14
Doing timestep 15
Doing timestep 16
Doing timestep 17
Doing timestep 18
Doing timestep 19
Doing timestep 20
<a class="moz-txt-link-abbreviated" href="mailto:mm@cy-2.lanl.gov">mm@cy-2.lanl.gov</a> {11}% tail log.0000.out
TIMINGS (process:event,running,cpu,wall,100*(wall/total wall))
0 : total time F 0.00000 196.55210
0 : initialize F 0.00000 67.82460 34.51
0 : time integration F 0.00000 11.05870 5.63
so the 'F' is a clue, but i don't know what it means. note that the
grid.nc file looks ok, and i successfully ran the 4/10 version of this
grid earlier this week.
any hints? maybe not enough memory? there are about 6 million cells...
thanks...
