      Results of a parallelization effort as applied to 3D heat transfer computations are described. The basic approach to numerical solution of the systems of 3D implicit finite-difference equations is the method of direction-based splitting. Two fundamentally different approaches to the organization of the massively parallel computations were developed. Parallelization efficiencies of the developed algorithms obtained on the MP-3 and Meiko computational systems are reported.



NUMERICAL RESEARCH ON THE PARALLELIZATION ALGORITHMS FOR 3D NEUTRON DIFFUSION AND TRANSPORT COMPUTATIONS IN THE SATURN CODE ON MULTIPROCESSOR COMPUTERS

VANT. Ser.: Mat. Mod. Fiz. Proc 1996. Вып.4. С. 16-23.

      Parallelization algorithms for 3D group neutron diffusion and transport computations on distributed-memory multiprocessor computers implemented in the SATURN code are considered.
      We present the results of testing the parallelization algorithms on the home-made 8-processor system MP-3 and foreign distributed-memory multiprocessor systems (up to 256 processors) Cray T3D and IBM SP2.



DOMAIN-BASED PARALLELIZATION OF CONTINUUM MECHANICS COMPUTATIONS ON THE MP-3 8-PROCESSOR DISTRIBUTED-MEMORY COMPUTER

I.D. Sofronov, Yu.A. Bondarenko, O.A. Vinokurov, V.V. Zmushko, F.A. Pletenev, P.V. Rybachenko, V.A. Saraev
VANT. Ser.: Mat. Mod. Fiz. Proc 1996. Вып.4. С. 24-28.

      Parallelization techniques for an explicit and an implicit difference scheme are described. The explicit scheme was used for multidimensional gas dynamics equations, and the implicit scheme, for the 2D heat transfer equation. Computational results are reported.



CONSTRUCTING DIFFERENCE SCHEMES FOR 2D UNSTEADY ELASTOPLASTIC FLOW COMPUTATIONS BASED ON THE LAW OF MUTUAL CONVERSION OF KINETIC AND INTERNAL ENERGY

V.I. Delov, O.V. Senilova, I.D. Sofronov
VANT. Ser.: Mat. Mod. Fiz. Proc 1996. Вып.4. С. 67-72.

      An approach to the construction of conservative differential-difference representations of equations to describe unsteady elastoplastic flows in Lagrangian variables is proposed. 2D axially symmetric motion of an isotropic elastoplastic medium is considered. Results of computations by a difference scheme of the second order of approximation in time obtained using the constructed differential-difference equations of motion are reported.
