lat_ops - basic CPU operation parallelism
lat_ops [ -W <warmups>
] [ -N <repetitions> ]
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.
This benchmark is highly
experimental and may sometimes (frequently?) give erroneous results.
