LAT_OPS(8) LMBENCH LAT_OPS(8)NAMElat_ops - basic CPU operation parallelism
SYNOPSISlat_ops [ -W <warmups> ] [ -N <repetitions> ]
DESCRIPTIONlat_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 opera‐
tions.
uint64 bit, add, mul, div, mod operations
maximum parallelism for uint64 XOR, ADD, MUL, DIV, MOD opera‐
tions.
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.
