Cluster Application Resources ( OSCAR ) : design , implementation and interest for the [ computer ] scientific community

The Open Source Cluster Application Resources (OSCAR) project is the founding working group of the Open Cluster Group (OCG). The OCG is an informal group of people dedicated to making cluster computing practical for high performance computing and more recently, clustering in general (high availability, diskless). OSCAR is a package that makes it easy to build clusters for high performance computing. Everything you need for a cluster – installation and configuration, maintenance, [parallel] programming, queuing system, scheduler – is included in OSCAR. In this article we will present a brief history of OSCAR, the actual components of OSCAR as well as the design and implementation proposal for OSCAR 2.1 and beyond.
