Users access it via computer network. System Paradigm • High Performance Computing System – Parallel Programming, e.g. MPI • High Availability System – Database System, e.g MySQL Cluster • Load Balancing System – Web Searching Engine, e.g. Yahoo Hardware Software • Linux Operating System – Red Hat Linux Distribution – Fedora Linux Distribution • Programming Tools – MPI, PVM • Cluster-Ready Application – MySQL Cluster, Oracle • System Monitoring Tools – e.g ganglia SLIM • Usually each individual PC is manually installed with Linux OS. • This creates much setup burden when the number of PCs is large • SLIM (Single Linux Image Management) is a solution developed by the Department of CS to ease the deployment and management issue. SLIM • SLIM server to provide shared Linux OS via the network to the client PCs. Client PCs
