HP OpenVMS Systems Documentation

Displays fastpath port assignment and usage. SHOW FASTPATH is useful for evaluating the distribution of interrupts among the various CPUs in complex configurations.

Format

SHOW FASTPATH

Qualifiers

/CPU=n[,...]

Requests fastpath information for one or more specific CPUs. By default, information is displayed for all CPUs.

/OUTPUT[=filename]

/NOOUTPUT

Controls where output from the command is sent. If you omit the /OUTPUT qualifier or omit the file specification with the qualifier, the display is written to the current SYS$OUTPUT device by default. If you enter the /NOOUTPUT qualifier, output is suppressed.

Examples

$ SHOW FASTPATH
Fast Path preferred CPUs on NODE1 23-MAY-2004 16:47:58.10
HP rx2600  (900MHz/1.5MB) with 2 CPUs
Device:           Fastpath CPU:
