NAME
       cluster-description - cluster description file

DESCRIPTION
       The cluster-description is a text file description of a cluster that is
       used by cmnodes(1).  It can describe the cluster manager, the  hardware
       platform  as  well  as  specify names for various nodes and node groups
       used by cmnodes (1).

       Lines starting with '#' are ignored, as are blank lines.   Some  things
       are  described by Key : Value pairs, and node list blocks are delimited
       by Begin and End tags.

KEY VALUE PAIRS
       The key and value are separated by the colon (:) character.

       HardwarePlatform
              The cluster's hardware platform.  Possible values: ICE or XE

       ClusterManager
              Specifies which cluster manager is  present.   Possible  values:
              Tempo, PlatformManager, ISLE-CM, SGIMC.

       Diag   Specifies which node should be used as the diagnostics node.

       Admin  Specifies the admin node for Altix ICE clusters.

NODE LIST BLOCKS
       Compute Nodes
              The  list  of  compute  nodes.  Starts with BeginComputeList and
              ends with EndCompute.

       Leader Nodes
              The list of leader nodes.  Only valid for ICE clusters.   Starts
              with BeginLeaderList and ends with EndLeader.

       Service Nodes
              The list of service nodes.  Only valid for ICE clusters.  STarts
              with BeginServiceList and ends with EndService.

EXAMPLE
       Here is an example of a cluster-description file:

           # The hardware platform (ICE, XE)
           HardwarePlatform : ICE

           # The cluster manager (Tempo, PlatformManager, ISLE-CM, SGIMC)
           ClusterManager : PlatformManager

           # The machine where diags should be run.
           Diag: service 1

           # For ICE compute nodes
           BeginComputeList
               r1i0n0
               r2i3n4
               r3n2n2
               r4n1n1
           EndCompute

           # For ICE, list of service nodes
           BeginServiceList
               service0
               service10
               service20
           EndService

           # For ICE, the list of leader nodes
           BeginLeaderList
               r1lead
               r2lead
               r3lead
               r4lead
           EndLeader
