Industrial Baltic sea water dynamics modelling program optimization and parallelization is described. Program is based on solving the system of partial dierential equations of shallow water with numerical methods. Mechanical approach to program modernization is demonstrated involving building module dependency graph and rewriting every module in specic order. To achieve desired speed-up the program is translated into another language and several key optimization methods are used, including

The list of applied program transformations is presented along with achieved speed-up for most time-consuming subroutines. Entire program speed-up results on shared memory computer system are presented.
