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.
Warewulf is more along the lines of a distributed Linux distribution, or more specifically a system for replicating and managing small, lightweight Linux systems from one master. Using Warewulf, HPC packages such as LAM/MPI / MPICH , Sun Grid Engine , PVM , etc. can be easily deployed throughout the cluster.
The Linux world supports various cluster software; for application clustering, there is distcc, and MPICH. Linux Virtual Server , Linux-HA – director-based clusters that allow incoming requests for services to be distributed across multiple cluster nodes.
The High Availability Add-On is Red Hat's implementation of Linux-HA. It attempts to ensure service availability by monitoring other nodes of the cluster. All nodes of the cluster must agree on their configuration and shared services state before the cluster is considered to have a quorum and services are able to be started.
RIP (Real IP address): the IP address used to connect to the cluster nodes; DIP (Directors IP address): the IP address used by the director to connect to network of real IP addresses; CIP (Client IP address): the IP address assigned to a client computer, that it uses as the source IP address for requests being sent to the cluster
xCAT can: Create and manage diskless clusters; Install and manage many Linux cluster machines (physical or virtual) in parallel; Set up a high-performance computing software stack, including software for batch job submission, parallel libraries, and other software that is useful on a cluster
Rocks Cluster Distribution (originally NPACI Rocks) is a Linux distribution intended for high-performance computing (HPC) clusters.It was started by National Partnership for Advanced Computational Infrastructure and the San Diego Supercomputer Center (SDSC) in 2000. [2]
The Linux-HA (High-Availability Linux) project provides a high-availability solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS). [1] The project's main software product is Heartbeat, a GPL-licensed portable cluster management program for high-availability clustering. Its ...
