Hi,
I am trying to implement the cell perturbation method in this paper: https://link.springer.com/article/10.1007/s10546-014-9956-9
The ideal is simple, we add a uniform random to the potential temperature field to each 8x8 gridpoint cell around the boundary, there are 3 cell (24 gridpoint at each boundary).
The problem arise when implement it distribulated memory parallell mode: each CPU can only see the data in each patch allocated to it.
Have any body implemented the method or have ideas to overcome this issue?
Many thanks in advance!
