PAR_OPS(8) LMBENCH PAR_OPS(8)NAMEpar_ops - basic CPU operation parallelism
SYNOPSISpar_ops [ -W <warmups> ] [ -N <repetitions> ]
DESCRIPTIONpar_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 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.
