In the last two decades, different architectures have been proposed and implemented for different requirements. Clusters are usually built on off-the-shelf PCs or workstations and local area networks. In some systems, special hardware are built to speedup communication for providing high-performance alternatives to expensive supercomputers. With the tremendous growth of Internet, some other systems are built on the Internet. These systems provide a highly scalable environment on the global area network. This dissertation is about studying the behavior and improving the performance of clusters. Two clusters are built for different requirements. One of the clusters is SPI, which is built using C on SCSI network to provide high-performance infrastructure. The other is IPI, which is built using Java on the Internet to provide highly scalable processing environment. Both clusters aim at providing cost effective solution for supporting parallel computing. The SPI is implemented as a Linux loadable service, which is driven by a device driver. the low-level layer is the SCSI adapter and the low-lever device driver which provides high performance data transmission facilities. The mid-level device driver provides messing facilities and the high-level device driver supports programming model to the parallel application programmers. The SPI is built on SCSI network which is inexpensive and high performance of SCSI. The SPI network has some unique properties and it is scalable. Six SCSI network topologies, Linear, Mesh, Circular, Cylinderical and Star, are proposed in this dissertation. Each of the topology has its unique features and the theoretical properties of the topologies are also presented. The IPI is an autonomous parallel environment that requires minimal human setup and administration effort. A centralized coordinator is responsible for managing the nodes of the environment. The joining and leaving of nodes are not restricted by the coordinator. The IPI supports process migration. When a node leaves the environment, partially finished tasks are migrated to other running nodes. The SPI and the IPI are two very different platform. The SPI is a high performance cluster on closed system network. The IPI is a highly scalable system on the Internet. This dissertation also presents a comparsion between the two systems with different scalability and performance. In short, SPI is a high performance system for medium grain applications, where IPI is a highly scalable system for coarse grain applications.
