[MITgcm-devel] OpenAD verification test

[Jean Utke]

Hi Jean-Michel,

In my own regression testing I am comparing some outputs directly without
using the reference output in the repository and it seems that between
11/17
(or 11/18) and now the cost function  output of a simple setup changed
somewhat
as you see below:   (old<  vs new >)
<   local fc =  0.804679274767541D+06
<  global fc =  0.804679274767541D+06
---
>   local fc =  0.804687744759401D+06
>  global fc =  0.804687744759401D+06

This running the plain mitgcm code (no AD involved). 
I wanted to verify with you that this is an expected change,,,
I am asking this because the value of the cost function in this test has
not
changed for a long time...
Please let me know either way so I update my regression tests

Jean
