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.
