[MITgcm-support] cubeSphereExchange and MPI error?

[Jean-Michel Campin]

Hi Anthony,

There is no need for apologies here, just that I did not mange to
answer anything useful.

And let's start with the 2nd problem:
> (PID.TID 0000.0001) *** ERROR *** EESET_PARMS: Error reading
> parameter file "eedata"
This usually happen when something is not right in the EEPARMS
namelist (in file "eedata").
Note that most (if not all) of the eedata files that are provided
in the various verification/*/input*/eedata contain this comment
# Lines beginning "#" are comments
where "beginning" means the line first caracter.
I am wondering if, in your case:
>  &EEPARMS
>  #useCubedSphereExchange=.TRUE.,
>  #usingMPI=.TRUE., (specified with ' -mpi' when compiling)
>  nTx=1,
>  nTy=1,
>  &
the comment-control caracter "#" is not in 2nd position ?

And regarding the first problem, can you check that
PACKAGES_CONFIG.h (produced by genmake2), contains
#define ALLOW_EXCH2
Otherwise, when you start from a cleaned build/ dir,
what is the genmake2 command you type ? and how does the
beginning (first 100 or 150 lines) of "Makefile" looks like ?
And finally, could you attached the file:
 ini_threading_environment.f (small ".f")
after compiling from this clean-build dir (and assuming you get
the same error when trying to run) ?

Cheers,
Jean-Michel
