pset_info

pset_info(1)						      General Commands Manual						      pset_info(1)

NAME

       pset_info - Displays processor set information

SYNOPSIS

       /usr/sbin/pset_info

DESCRIPTION

       The pset_info command displays information about processor sets and the processors that are assigned to each set.  Note that a stopped pro-
       cessor is not a member of any processor set, and its processor set identification number is specified as -1. Also, depending on the machine
       architecture, processors may not be numbered consecutively.  That is, a four-processor system may not have a processor with the number 3.

NOTES

       If  a  processor or processor set is queried while it is in transition (for example, processor set destruction or processor assignment), an
       error may be returned from the kernel.  Running the command a second time will result in normal behavior.

EXAMPLES

       The following is an example of the output of the pset_info command:

       number of processor sets on system = 2

       pset_id	# cpus	 # pids   # threads  load_av	created
	 0	   1	    26	     63        0.90	09/21/1994 17:48:42
	 6	   1	    1	     4	       0.21	09/21/1994 23:33:37

       total number of processors on system = 3

       cpu #	running  boot_cpu pset_id  assigned_to_pset
	0	   1	     1	     0	   09/21/1994 17:48:42
	1	   1	     0	     6	   09/21/1994 23:34:06
	2	   0	     0	      -1   09/21/1994 17:48:42
