OSCAR Clusters
The Open Source Cluster Application
Resources (OSCAR) is a cluster software
stack providing a complete infrastructure
for cluster computing. The OSCAR project
started in April 2000 with its first public
release a year later as a self-installing
compilation of "best practices" for
high-performance classic Beowulf cluster
computing. Since its inception approximately
three years ago, OSCAR has matured to
include cluster installation, maintenance,
and operation capabilities and as a result
has become one of the most popular cluster
computing packages worldwide. In the past
year, OSCAR has begun to expand into other
cluster paradigms including Thin OSCAR, a
diskless cluster solution, and
High-Availability OSCAR, embracing fault
tolerant capabilities. This paper will
cover the current status of OSCAR including
its two latest invocations - Thin OSCAR and
High-Availability OSCAR as well as the
details of the individual component
technology used in the creation of OSCAR.
