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