lat_ops(8)
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.
