Installation Method

Several methods are available for installing the grid engine software:

• Interactive

• Interactive, with increased security

• Automated, using the inst_sge script and a configuration file

• Upgrade

To decide which installation method you should use, consider the following factors.

• Do you already have the grid engine software installed and running?

  If so, you'll probably want to upgrade. The upgrade process is described in Chapter 5, Upgrading From a Previous Release of N1 Grid Engine Software.

  If not, the master host installation is only done once, so the master host is typically installed interactively, as described in Chapter 2, Installing the N1 Grid Engine Software Interactively.

• Do you need to install just a few execution hosts?

  If so, then you will probably want to install them interactively, as described in Chapter 2, Installing the N1 Grid Engine Software Interactively.

• Do you need to install a large number of execution hosts?

  If so, then you might want to perform automated installation, using the inst_sge script and a configuration file. This process is described in Using the inst_sge Utility and a Configuration Template.

• Do you require your grid to use encryption?

  If so, you have to perform an interactive installation with increased security. This process is described in Chapter 4, Installing the Increased Security Features.
