Add a host type or model

The ego.shared file contains a list of host type and host model names for most operating systems. You can add to this list or customize the host type and host model names. A host type and host model name can be any alphanumeric string up to 39 characters long. The ego.shared file, which is accessed by the master host, is located in the EGO_CONFDIR directory.

  1. Log on to the OS as the cluster administrator user.
  2. Edit ego.shared:
    1. For a new host type, modify the HostType section:
      Begin HostType
      TYPENAME                     # Keyword
      DEFAULT
      IBMAIX564
      LINUX86
      LINUX64
      NTX86
      NTX64
      NTIA64
      SUNSOL
      SOL732
      SOL64
      SGI658
      SOLX86
      HPPA11
      HPUXIA64
      MACOSX
      End HostType
    2. For a new host model, modify the HostModel section:

      Add the new model and its CPU speed factor relative to other models.

      Begin HostModel
      MODELNAME  CPUFACTOR   ARCHITECTURE # keyword
      # x86 (Solaris, Windows, Linux): approximate values, based on SpecBench results
      # for Intel processors (Sparc/Win) and BogoMIPS results (Linux).
      PC75             1.5   (i86pc_75  i586_75  x586_30)
      PC90             1.7   (i86pc_90  i586_90  x586_34 x586_35 x586_36)
      HP9K715          4.2   (HP9000715_100)
      SunSparc          12.0         () 
      CRAYJ90           18.0         () 
      IBM350            18.0         () 
      End HostModel
  3. Save the changes to ego.shared.
  4. Restart EGO on the master host so that the changes can take effect:

    egosh ego restart
