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.
