Detailed Description

Interface for distributed ARTS forward model.

This special forward model wrapper parallelizes the ARTS mblock calculations over the different MPI processes. Each process only computes a limited range of rows of the measurement vector y and the Jacobian. The measurement vector is returned as a full vector to each process which requires broadcasting the results after the computation.
