Description

Context

In NEMO namelists are read by all processors. This ticket is to implement reading of the namelists by single processors and broadcasting the data.

Implementation plan

a) Read namelist using single processor
b) broadcast the data to all processors.

This task will require an extension of lib_mpp.F90. New subroutines are needed to handle broadcasting of different types of data (from namelists).

It looks that sbc_init must be called before the first mpi communication associated with namelist read. Unfortunately moving sbc_init results in result change for GO6. The problem seems to be only during restart, first cycle was OK
