As the system size of Beowulf-Class cluster system scale up, system administration becomes challenging due to the increases complexity of the system. The lack of powerful tools for the administrative tasks even make the matter worse. This paper presents a proposed framework for system management of large Beowulf cluster that divided the management task into well defined layers of service. A cluster management tools called SCMS (SMILE Cluster Management System) has been developed according to this framework. SCMS provides a rich set of services and tools for large cluster administration. The current implementation of SCMS is discussed referenced to the proposed framework. The software is now freely available on Internet. 1 Introduction and Motivation One of the important class of cluster system is BeowulfClass cluster[10] which emphasis on the use of commodity hardware technology and opensource software to deliver a very high-performance at extremely low cost. Many organizations has s...

With the speed and bandwidth offered by the next generation Internet technology, there is a need for large and scalable Internet server that can provides an adequate computing power and storage for the new generation Internet applications. This requires a huge investment in a very large and expensive commercial server system. Recently, the emergence of Linux PC clustering or so-called Beowulf Cluster Computing technology has provided a very low cost, scalable, and high-performance alternative to using these commercial superserver system in many class of applications. This paper presents our experiences learned from the construction of a 72 nodes Beowulf Class Cluster called PIRUN (Pile of Inexpensive and Redundant Universal Nodes) Cluster at Kasetsart University, Bangkok, Thailand. The purpose of this project is to explore the use Linux PC clustering technology to build a central Internet superserver and supercomputing class system for academics support at the university level. In this paper, the planning of the system is presented along with the discussion about issues in both hardware and software. This system when fully exploited will cost the same as current same main server but offer about 30-40 times more computing power and storage. Moreover, PIRUN System will becomes the largest supercomputing system in Thailand and deliver about 3 times higher performance than the previous largest supercomputing system in Thailand. We strongly believe that this type of system and technology is very suitable for developing countries in Asia Pacific Region.
