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 latency  di-
     vided  by the minimum average operation latency across all levels of paral-
     lelism.

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

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

     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.
