The Construction and Test for a Small Beowulf Parallel Computing System

As a practical scheme carrying out the high performance computing tasks for small research groups and personal researchers, we propose a small Beowulf PC-cluster parallel system based on MPI and Windows by employing a set of PCs and 100 M Ethernet. The experimental evaluations on the classical case of computing ¿ show that the system has satisfactory speedup and parallel efficiency. Owing to the 100 M Ethernet which has less bandwidth and more communication delay, the speedup and parallel efficiency will come down with increasing working nodes, and a more excellent high speed network should be build.
