A description is given of an algorithm for parallelizing numerical solution of 2D gasdynamic problems on nonstructural grids for a single mathematical domain on distributed memory computation systems. Difference and finitedifference equations, a method of solving finitedifference equations system, a method of a solution domain decomposition are presented. On distributed memory MP3 computation system a study was made of accuracy of algorithm for numerical solution of 2D problem on RichtmyerMeshkov instability evolution. The estimations of parallelization efficiency on the number of processors up to 8 are given.
