Compaq 300 manual Configuration Recommendations, Tuning Techniques

Installation (Compaq Tru64 UNIX)

The installation is now completed.

6.4 Configuration Recommendations

Compaq recommends performing the following configuration operations before you use PowerStorm 300/350 UNIX Graphics Support:

∙Partitioning Drives

You should define a minimum of 600 MB pages of swap.

For any system, you should divide swap space equally across two or more drives. No swap partition should be smaller than 100 MB pages.

Example 1:

A system with two drives could be configured to contain the following:

drive1: operating system and swap1

drive2: 3D client application, user data, and swap2

Example 2:

A system with three disks could be configured to contain the following:

drive1: operating system and swap1

drive2: 3D client application, user data, and swap2

drive3: user model data

∙Configuring Physical Memory (RAM)

You should configure enough physical memory for the average workload to reduce paging activity to zero.

The minimum memory requirements are determined by the size of the data and the application operations. On Tru64 UNIX systems, most three-dimensional graphics applications require an absolute minimum of 128 MB.

6.4.1Tuning Techniques

When tuning a Tru64 UNIX system, the most important goals are to minimize paging and to use the physical memory as efficiently as possible. If your system has too little physical memory, these goals are extremely difficult to attain.

The recommended method for configuring PowerStorm 300/350 UNIX Graphics Support on Tru64 UNIX Version 4.0E or 4.0F is to use the /sbin/sysconfig utility. First, you should determine which subsystems are configured:

# sysconfig -s
