Preparing for software installation
Prerequisites
The following conditions must be met before performing the installation.
- The front-end workstation must be either a Sun4 running SunOs 4.1.1
or higher
- The workstation must have
- X11 R4 or R5
- Modif window manager (mwm) version 1.1.4
- The host system and your working directory must each have a certain
amount of disk space:
Sun4: 6.5 MB of temporary storage (for the tar file) and
6.5 MB of permanent storage
- The host system must have a standard 1/4'' tape drive
- You must have root privileges to complete the several steps of the
installation
- You must have roughly two hours to complete this installation
Preliminaries
The CNAPS Server is a server because it provides a service (parallel
computation) in a networked environment. Installing the CNAPS
Server on an Ethernet network requires working with existing software
servers and creating new servers. The relevant servers are as follows:
- NIS server: the workstation offering Network Information Services
(NIS, also called the Yellow pages.) You can install the
CNAPS Server with or without NIS.
- BootP server: the workstation that runs a program bootpd
that supplies information to the CNAPS Server during its boot
process. This new server will be created during control
software installation.
The TFTP service must be enabled on the BootP server.
- CPsim server: the workstation that runs the CPsim simulator
program. This new server will be created during control software
installation.
Depending on your network, each service might run on any workstation.
All might run on different workstations, or all on one, in any
combination.
We selected
- gsu as the NIS server
- sparc (suppose) as the workstation which provides all the services
Some topics you may want to address include the following:
- Determine the best location in your file system for the extracted
files. A typical choice might be to place the extracted files in
a new directory called adaptive under /usr/local.
Our choice is /usr/adaptive since in our system,
the /usr/local is a symbolic link to /gsusr/local. We have no
right to write into it. The ADAPTIVE is /usr/adaptive.
- Determine which users need access to the CNAPS files. We put
the files into /usr so that every one can access the CNAPS files.
- CPsim is a program that emulates a CNAPS Server. Cpsim is far
slower than a "real" Server. CPsim can run as multi-user
server or as a single-user process. Our choice is multi-user
server.
- Install on-line manual pages into /usr/man/man1
- The CNAPS X Window tools are installed in /usr/lib/X11/app-defaults
- The file /usr/lib/X11/XKeysymDB exists in our system
- The Ethernat number assigned to the CNAPS Server is:
- The Internet Protocol (IP) number is: 141.165.41.97 cnaps.
- The NIS server is: gsu
- The workstation for running BootP is: sparc
