Hardware Architecture

hwarch.JPG

The server node and the computing nodes are connected to a high-speed gigabit switch as shown in the figure. The nodes are powered by a Intel Pentium IV CPU which are cheaper in terms of cost and provide a good enough speed. A Gigabit LAN provides a decent network for a cluster of small size. Other options like Myrinet, Infiniband can be used for serious cluster applications. A KVM (Keyboard, Video, Mouse) switch is used to control all the nodes of the cluster using a single keyboard, video and mouse source. The KVM switch helps to switch between different nodes of the cluster thereby facilitating to use a single keyboard, mouse and monitor for all the nodes in the cluster.
