f Portable Parallel, Code for Depth Migration

We have ported a serial code for 2D seismic depth migration to parallel platforms. The porting was done using portable parallel primitives, such that the same code can be run on a number of parallel machines, workstation clusters, as well as serial machines. Only small modifications of the serial code was necessary. An efficient, parallelization of the code was obtained. The computing time scales well with the number of processors.
