par_ops: basic CPU operation parallelism

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 divided by the minimum average operation latency across all levels of parallelism. 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.
