A cluster is a group of computers which work together toward a
final goal. Some would argue that a cluster must at least consist of a
message passing interface and a job scheduler. The message passing
interface works to transmit data among the computers (commonly called
nodes or hosts) in the cluster. The job scheduler
is just what it sounds like. It takes job requests from user input or
other means and schedules them to be run on the number of nodes required
in the cluster. It is possible to have a cluster without either of these
components, however. Consider a cluster built for a single purpose.
By definition, however, a cluster must consist of at least two nodes,
a master and a slave. The master node is the computer that users are
most likely to interact with since it usually has the job scheduler
running on it. The master can also participate in computation like the
slave nodes do, but it is not required or even recommended in large
clusters. The slave nodes are just that. They respond to the requests of
the master node and, in general, do most of the
computing.
