DESCRIPTION
A boot schema describes the machines that will combine to form a multicomputer running LAM. It is used by recon(1) to verify initial conditions for running LAM, by lamboot(1) to start LAM, and by wipe(1) to terminate LAM.

The particular syntax of a LAM boot schema is sometimes called the "host file" syntax. It is line oriented. One line indicates the name of a machine, typically the full Internet domain name, and optionally the userid with which to access it.

Common boot schemata for a particular site may be created by the system administrator and placed in the installation directory under boot/. They typically start with the prefix bhost. Individual users usually create their own boot schemata, especially if the configurations are simple.

EXAMPLE
Here is an example three node boot schema:

#

beowulf2.nd.edu
somewhere.else.college.edu guest
