jperio = 4: nogather and gather differ... to be solved...
jperio = 6 is ok (at least on our bench tests...)

comment:9 Changed 6 years ago by smasson
Warning: [10175] change the results because in fortran (a + b) + c /= a + (b + c )...
For example, in north fold, triad won't be computed in the exact same order, creating very small differences in duplicated grid points (2 points of the grid having the same geographical location).

comment:13 Changed 6 years ago by emalod
Warning: [10180] change the results because convergence criteria in icethd_zdf_bl99 subroutine is changed.
Before: convergence loop is stopped in all MPI sub-domains when criteria is fulfilled everywhere.
Now: convergence loop is stopped locally for each MPI sub-domain and, at each point, the variable is filled with the value obtained when criteria is fulfilled in that point (and not the value got when criteria is fulfilled everywhere in the whole sub-domain)
In both cases, the results are MPI-decomposition independent but they are changed by the implementation.
