A cluster of workstations is increasingly used in many organizations including industries as well as academic institution for automation. As off-the-self components are widely available and becoming cheaper, the cluster of workstations (or simply clusters) is becoming popular compared to traditional high cost supercomputers. Due to their high scalability, clusters can be tuned to performance requirement of computational intensive applications. Nevertheless communication intensive applications (such as Google, Yahoo, Amazon clusters) can exploit the performance advantages of clusters as well.
