breakall

Display or change whether all target processors start and stop together in a multiprocessor system.

Syntax

breakall [= bool-cond]

Where:

bool-cond

specifies a number of an expression that must evaluate to true (non-zero) or false (zero).

Discussion

Use the breakall control variable to control whether all target processors in a multiprocessor system start and stop together. The default setting for breakall is true. Entering the control variable without an option displays the current setting. ย 

If breakall is set to false, each processor in a multiprocessor system can be controlled independently of the others. A viewpoint override or the current viewpoint in which the go command is used determines which processor is run.

If breakall is true, all processors in a multiprocessor system start when a go operation is executed.

Example 1

Command input:

breakall ย ย ย ย ย ย ย ย ย ย // display the current setting

Result:

true

Example 2

Command input:

breakall=false
go ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย // only viewpoint processor is run

Example 3

Command input:

breakall=false
[p0]go ย ย ย ย ย ย ย ย ย ย ย ย // P0 processor override used to run only P0 processor
