The paper presents the description of parallel algorithms for solving 3D heat conduction equation and computation results of test problem on cube cooling obtained using eightprocessor computer system MP3 with distributed memory. Differentia] and finitedifference equations, scheme of spliting by directions, finitedifference equation solving technique are given. Two approaches to massively parallel computation arrangement are implemented and studied. Parallelization efficiency dependence on technique of problem geometrical decomposition for two modes of MP3 processor loading is investigated. Computations were carried out using orthogonal and nonorthogonal grids.
