Open Source Cluster Application Resources (OSCAR) is a Linux based software installation for high-performance cluster computing.OSCAR allows users to install a Beowulf type high performance computing cluster. Beowulf Clusters are scalable performance clusters based on commodity hardware, on a private system network, with an open source software (Linux) infrastructure. The OSCAR project aims to support as many different Linux distributions as possible. Supported Linux distributions as mentioned on the OSCAR website are Debian, Fedora, OpenSUSE, Red Hat Enterprise Linux and Ubuntu. It consists of a cluster of PCs or workstations dedicated to running high performance computing tasks. The nodes in the cluster don't sit on people's desks; they are dedicated to running cluster jobs. The cluster is usually connected to the outside world through only a single node.
