Wei-Keng -- do you have some explanation of the tool output?<br>
I have this, for example:<br>
<blockquote><tt>DIFF: global attribute "history" length (31) != (30)<br>
DIFF: global attribute "config_run_duration" of type "NC_CHAR"
(3)<br>
DIFF: global attribute "file_id" of type "NC_CHAR" (3)<br>
DIFF: variable "ru" of type "NC_FLOAT" (158)<br>
DIFF: variable "ru_save" of type "NC_FLOAT" (-185)<br>
DIFF: variable "rw" of type "NC_FLOAT" (-91)<br>
DIFF: variable "rw_save" of type "NC_FLOAT" (101)<br>
DIFF: variable "rtheta_p" of type "NC_FLOAT" (77)<br>
DIFF: variable "rtheta_p_save" of type "NC_FLOAT" (-47)<br>
DIFF: variable "rho_p" of type "NC_FLOAT" (42)<br>
DIFF: variable "rho_p_save" of type "NC_FLOAT" (-35)<br>
DIFF: variable "rho_zz_old_split" of type "NC_FLOAT" (83)<br>
DIFF: variable "ruAvg" of type "NC_FLOAT" (-151)<br>
DIFF: variable "ruAvg_split" of type "NC_FLOAT" (15)<br>
DIFF: variable "wwAvg" of type "NC_FLOAT" (-93)<br>
DIFF: variable "wwAvg_split" of type "NC_FLOAT" (-70)<br>
Number of differences in header 3<br>
Number of differences in variables 13</tt><br>
</blockquote>
Most of these are arrays, is this reporting the largest absolute
difference across all the elements?<br>
