A cluster usually consists of:
- a group of compute host machines, and
- a cluster server used for the following purposes:
- a file server for SCore cluster administration
the Cluster Database Server, scoreboard
, and
the Compute Host Lock Server, msgbserv
are running
on this computer
- software development compilation
- running cluster maintenance daemons
For instance, if you want to build a cluster of 8 compute hosts,
you need to buy 9 computers.
Though we recommend having a cluster server,
you may install software for the cluster server onto one of the compute hosts,
so that you don't need to buy a computer for the server.
A router is also necessary if you plan to connect the cluster to a LAN.
All processor hosts forming a homogeneous cluster should be of the same
architecture and use the same version of the operating system.
