Cloud Computing on Ulitzer Computational science is the field of study concerned with constructing mathematical models and numerical techniques that represent scientific, social scientific or engineering problems and employing these models on computers, or clusters of computers, to analyze, explore or solve these models. Numerical simulation enables the study of complex phenomena that would be too expensive or dangerous to study by direct experimentation. The quest for ever higher levels of detail and realism in such simulations requires enormous computational capacity, and has provided the impetus for breakthroughs in computer algorithms and architectures. Due to these advances, computational scientists and engineers can now solve large-scale problems that were once thought intractable by creating the related models and simulate them via high-performance compute ...

Toward Highly Available Linux Clusters

This article describes the HA-OSCAR architecture and features, and demonstrates how to set up a highly available Linux cluster using the first beta release of HA-OSCAR version 1.0. Introduction In 2002, Ibrahim Haddad, Chokchai Leangsuksun, and Stephen L. Scott established the HA-OSCAR (High Availability OSCAR) project with a primary goal of leveraging the existing OSCAR (Open Source Cluster Application Resources) technology while providing high-availability and scalability capabilities for Linux clusters. The OCG (Open Cluster Group) recognized the project as an official workin... (more)
