[MITgcm-support] Any tutorials on the MITgcm adjoint model

[Patrick Heimbach]

Hi Xiangming,

your detailed error reports are somewhat incomplete, but some guesses:

1. you probably didn’t set the proper environment variables after installing OpenAD
(see http://www.mcs.anl.gov/OpenAD/access.shtml)

2. Try running, initially using simple gfortran compiler, testreport for experiment OpenAD,
i.e. in directory verification/ do:
./testreport -oad -t OpenAD

This will generate the adjoint using your OpenAD install 
(assuming you’ve set all environment variables properly),
compile it, run it, and compare the results against a reference output.
It did work as of early this morning
(see http://mitgcm.org/testing/results/2014_07/tr_acesgrid-openad_20140728_0/summary.txt )

3. The README in verification/OpenAD is indeed a bit out of date - sorry.
We’ve considerably simplified the build process for OpenAD over the last year.
Will need to update (simplify) the description soon.

Cheers
-Patrick
