Throughout this documentation, the path /nqebase is used in place of the default NQE path name, which is /opt/craysoft/nqe on UNICOS, UNICOS/mk, and Solaris systems and is /usr/craysoft/nqe on all other supported platforms.
NQE 3.3 is installed into /nqebase.
Figure 3-1, shows the NQE directory structure; the installed components are put into the directories shown in the figure. The symbolic links to the /nqebase/$NQE_VERSION directories are built when you run the nqemaint(8) command and click on the Make Default button.
The dependencies file includes a list of the supported operating systems and release levels. It also includes dependencies that you should be aware of before you start NQE. This information is also included in this NQE installation guide.
The news file contains descriptions of the new features and user-level compatibilities and differences. This information is also included in the NQE Release Overview, publication RO-5237 3.3, which is included with each NQE 3.3 release package.
Each version of NQE is a complete copy in its own directory. Therefore, you can have any number of versions of NQE loaded. The link, /nqebase/bin, points to the default version of NQE. You can change this link by using the NQE version maintenance utility, which is invoked by the nqemaint(8) command. For information about using the nqemaint(8) command, see Chapter 13, “NQE Version Maintenance Utility”.
