Parallel Algorithms for Solution of Air Pollution Inverse Problems
ABSTRACT Parallelization of Marchuk’s method for solution of inverse problems based on adjoint equations and dual representation of
contaminant concentration functional is considered here. There are N individual adjoint equations independently solved at
each time step. Such conditions of numerical investigation allow application of high performance computations. For this purpose
the following ways of parallelization are used: geometrical decomposition, functional decomposition and combination of geometrical
and functional decompositions.

ABSTRACT: Fromm's second-order scheme for integrating the linear convection equation is made monotonic through the inclusion of nonlinear feedback terms. Care is taken to keep the scheme in conservation form. When applied to a quadratic conservation law, the scheme notably yields a monotonic shock profile, with a width of only mesh.Journal of Computational Physics 03/1974; 14(4-14):361-370.
