PARALLEL COMPUTING IN A NETWORK OF WORKSTATIONS

Abstract

In this paper we describe a few architectures and software for parallel-processing computers. We have tested a cluster constructed with the use of MPI. All tests have been performed for one- and two-dimensional magneto-hydrodynamic plasma. We have concluded from the results of these tests that a simple problem should be run in a sequential node, as its execution time does not essentially decrease with the number of processors used. At the same time, the execution time of a complex problem decreases significantly with the number of processors. In the case of twodimensional plasma the acceleration factor has reached the value of 3.7 with the use of 10 processors.

Keywords:
