Another good contender for clustering is the OpenSSI project
(http://OpenSSI.org/). It provides a more comprehensive form of SSI
clustering than Mosix, because every process in an OpenSSI cluster can
transparently access all usable resources in the cluster (filesystems,
devices, IPC objects, other processes, etc.), rather than just the
resources of a "home" node. OpenSSI also has a complete set of HA
features that eliminate all single points of failure, assuming you
configure it with a shared RAID disk for the root filesystem. OpenSSI
supports migration of an entire process, including its kernel state, so
a migrated process is less vulnerable to node failure.
A big advantage of an OpenSSI cluster is that it makes the OS easy to
manage over a set of machines. It has only one filesystem tree for
installing, configuring and maintaining the OS and applications. It
presents a unified view of all processes in the cluster for easy
management of distributed applications and parallel servers. Its
complete set of HA features make it attractive for running 24/7 servers,
and its scalable architecture allows users to build tiny 2-node clusters
or massive 100+ node clusters.
OpenSSI has a community following, it runs on Debian, it's relatively
easy to port between distros, it has development support from a major
technology company, and it's very close to its 1.0 release.
