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 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.
