update-cluster is a package for managing a central list of machines and using that list to generate machine lists for other software. Provided commands include:

  • update-cluster-add and update-cluster-remove to maintain the XML cluster nodes list in /etc/update-cluster/cluster.xml by default (runtime options allow you to have multiple such files)

  • update-cluster-regenerate automatically builds machine lists for each package, e.g. running "update-cluster-regenerate jmon" rebuilds /etc/jmonrc

Currently the following packages use update-cluster to maintain their own machines lists:

  • jmon , a distributed resource monitor (CPU, memory, swap)

  • mpich , an implementation of MessagePassingInterface

  • mosix , which turns a cluster into a virtual multiprocessor machine with shared memory

  • update-cluster-hosts , which maintains a section of the /etc/hosts file

  • rarpd , used to boot diskless Sun boxes

  • dsh , distributed shell used to easily run commands on multiple machines

The initial list of cluster nodes can be created using debconf.
