A cluster is a collection of independent and cheap machines, used together as a supercomputer to provide a solution. In traditional scalable computing clusters, there is related high powered Intel or AMD based PC’s associated with several gigabytes of hard disk space spread around. As far as a cluster administrator is concerned, the installer may have to install an operating system and related software for each cluster node. Every node (excluding the Server) is equipped without any hard disk and is booted from the network. Since it has booted successfully, it works as same as a fully equipped one. We will explain how to set up a diskless cluster for computing purpose. In this paper, a SMP-based PC cluster consists of one master node and eight diskless slave nodes (16processors), is proposed and built. The system architecture and benchmark performances of the cluster are also presented in this paper.
