To emphasise the usability of cluster of workstations platform for parallel and distributed computing, also the paper presented the status report on the effort and experiences for the implementation of a dynamic load balancing for parallel tree computation depth first search(DFS) on the cluster of a workstations project.

The speedup results show that cluster of workstations can be a serious alternative to the expensive parallel machines.展开更多
