Availability (HA) Computing has
long been played a critical role in industry mission critical applications.
On the other hand, High Performance Computing (HPC) has equally been a significant
enabler to the R&D community for their scientific discoveries. With
combination of HA and HPC, together will clearly lead to even more benefits
to both industry, academic and research entities.
HA-OSCAR "High Availability Open Source Cluster
Application Resources" is an open source project aims to provide
a combined power of High Availability and Performance Computing solution.
Our goal is to enhance a Beowulf cluster system for mission critical grade
applications. To achieve high availability, component redundancy is adopted
in HA OSCAR cluster to eliminate this single point of failure. HA-OSCAR
incorporates a self-healing mechanism; failure detection & recovery,
automatic failover and fail-back.
