In Example 7-12 the user enters the command vet at the system
1
prompt. The system sizer message is displayed. The system sizer
process finds the devices that are connected to the system and obtains
device information needed by the VET programs.
At the VET_setup prompt, the user issues the command load. The
2
load command creates processes for most devices on the system. Note
that the File test exercises disks.
The VET program displays a series of questions. The user can select
3
the number of processes to run for each device type. In the example,
two processes are selected for the CPU device, memory device, and file
device.
