OpenSSI is intended to make a group of systems look like one system (SSI
means Single System Image). The idea is that the group is managed and
used as one system. I use openMosix for a similar purpose on a 92-node
Beowulf cluster under Ubuntu 6.06.1 LTS. However, this is a 2.4 kernel,
with no SATA support. The deb's are available here if you're interested:
I'm evaluating alternatives to openMosix at present, because there has
been an end-of-life announcement for openMosix. Moshe Bar, the founder
of the openMosix project, has decided to end the project because he
believes that large SMP machines eliminate the need for SSI clusters.
Not everyone agrees with him about that...
I'm particularly interested in Kerrighed as an alternative:
I think you might find that a DNS 'round-robin' and a server farm fits
your requirements better than SSI. The problem with SSI is the process
migration overhead on a single 'login' server. You also have to bear in
mind that not all processes can be migrated.
