PAR_OPS(8)			    LMBENCH			    PAR_OPS(8)

NAME
       par_ops - basic CPU operation parallelism

SYNOPSIS
       par_ops [ -W <warmups> ]	[ -N <repetitions> ]

DESCRIPTION
       par_ops	measures  the  available parallelism for basic CPU operations,
       such as integer ADD.  Results are reported as the average operation la-
       tency divided by	the minimum average operation latency across all  lev-
       els of parallelism.

       integer bit, add, mul, div, mod operations;
	      maximum  parallelism  for	integer	XOR, ADD, MUL, DIV, MOD	opera-
	      tions.

       uint64 bit, add,	mul, div, mod operations;
	      maximum parallelism for uint64 XOR, ADD, MUL,  DIV,  MOD	opera-
	      tions.

       float add, mul, div operations;
	      maximum parallelism for flot ADD,	MUL, DIV operations.

       double add, mul,	div operations;
	      maximum parallelism for flot ADD,	MUL, DIV operations.

BUGS
       This  benchmark	is highly experimental and may sometimes (frequently?)
       give erroneous results.
