A workable approach for modernization of existing software into parallel/distributed applications is through coarse-grain restructuring. If, for instance, entire subroutines of legacy code can be plugged into the new structure, the investment required for the re-discovery of the details of what they do can be spared. The resulting renovated software can then take advantage of the improved performance offered by modern parallel/distributed computing environments, without rethinking or rewriting the bulk of their existing code. In this paper, we discuss one of our experiments using the new coordination language M<font> size=-1>ANIFOLD</font to restructure an existing sequential numerical application written in Fortran 77, into a parallel/distributed application.
