A method to calculate the flow of a weakly compressible gas on 
a multiprocessor computer system using the ( - ) iteration 
algorithm has been proposed. The problem of gas flow in a cavity 
with a moving cover has been considered as an example. The flow 
is described using Navier-Stokes equations in natural variables; 
MAC-type spaced grids are employed. Calculations with the use of 
a monoprocessor version of the ( - )  algorithm and using its 
parallel implementation for the case of four processors have been 
carried out; the issue of the efficiency of multisequencing has 
been studied. Certain aspects of organization of remote access to 
the multiprocessor system have been discussed.
