"It's a bunch of scientists that don't know enough about system administration to realize that systems need administration." -- Daniel O. Cummings on scientists with supercomputers.
A Linux Virtual Server cluster is a highly-scalable and highly-available network service cluster built on a set of real servers. Here's how they work, and how you can set one up yourself.
Without serious Linux savvy, in- stallation and administration of a Beowulf cluster can be cumbersome and time con- suming, particularly when the cluster consists of more than a handful of nodes. Lack of a single system image -- one operating system controlling all nodes simultaneously -- makes day-to-day administration challenging. The result is that, without software tools, you must maintain each node individually.
