NAME
       lat_ops - basic CPU operation parallelism

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

DESCRIPTION
       lat_ops	measures  the latency of basic CPU operations, such as integer
       ADD.

       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.
