Name

cputst - CPU Test for Online CPU Diagnostics Monitor

Synopsis

/usr/platform/sun4u/sbin/sparcv9+vis2/cputst [-vnh] [ -s <stress_level> ] [ -d <dev_id> ]

Description

cputst primarily exercises and tests the Floating Point Unit (FPU) on Sun platforms supporting a minimum of UltraSPARC III family of processors. The FPU functionality is checked by performing FPU-oriented operations with single and double precision numbers. The computed results are verified against known good results.

Options

TABLE A-1 `cputst` Options
Option	Description
`-s` <stress_level>	1=low, 2=medium, 3=high. The default is 2.
`-d` <dev_id>	Specify the `processor_id` of the CPU to be tested. By default, all CPUs in the system are tested.
`-v`	Verbose Mode - the default is Verbose off.
`-n`	Notify `cpudiagd`(1M) for subsequent fault management. The default is no notification.
`-h`	Display help message.

Examples

Example 1: Using cputst to test all the CPUs with medium stress and without notification.

# ./cputst

Example 2: Using cputst to test CPU 20 with low stress, without notification, and with verbose messages.

# ./cputst -s 1 -v -d 20

Example 3: Using cputst to test all the CPUs, with medium stress, and with notification.

# ./cputst -n

Exit Status

0 - No failures or errors are detected in the system.

1 - Failures or errors are detected in the system.

2 - An internal cputst error occurred.
