Houston, we have a problem

[John Tannahill]

Jianwei,

You may be running at bit better, but still are having problems I
think.  The values in the netCDF output file should not be 0 and the
diff, delmax, delmin should.  The read/write timings look suspicious
and you get a couple of INF's (so do I).  My screen output is about
the same.  The main issue I think is that the netCDF data does not
appear to be written out.
