Red Hat Linux 7.3 Settings

  1. The server must be installed as follows:

    1. Package selections

      All RPM packages distributed with Red Hat Linux 7.3 must be installed. That is, the "Custom" menu item must be selected instead of "GNOME Workstation" on the "Install Type" panel. Further, select "Everything" on the Package Group Selection" to install all packages.

    2. Disk partition

      When choosing the filesystems to create, we recommend creating a file system called /opt with a space of 500MB to install the SCore system.

    3. No Firewall setting

      No firewall setting is required because nfsd and rlogind facilities must be enabled.

    4. FQDN

      The host name must be specified with a fully qualified domain name (FQDN).
      For example, server.pccluster.org, instead of just the host name server

  2. All compute hosts must be installed as follows in case of manual installation:

    If you use EIT, you do not need to install Red Hat Linux 7.3 on all compute hosts by hand. If you install the SCore system by hand, read the following instruction.

    1. Package selections

      All RPM packages distributed with Red Hat Linux 7.3 must be installed. That is, the "Custom" menu item must be selected instead of "GNOME Workstation" on the "Install Type" panel. Further, select "Everything" on the Package Group Selection" to install all packages.

    2. Disk partition

      When choosing the filesystems to create, we recommend creating a file system called /scored with a space of 1GB for checkpointing.

    3. No Firewall setting

      No firewall setting is required because rshd facility must be enabled.

    4. FQDN

      The host name must be specified with a fully qualified domain name (FQDN).
      For example, comp0.pccluster.org, instead of just the host name comp0

    5. Allow rsh by root

      rsh by root is required to make PM/ethernet config file and to start SCore-D multi user mode.
      Please add rsh in /etc/securetty as folows: 

          # echo rsh >> /etc/securetty
      Note that you must enable rshd(8) via xinetd(8).
