PAR_OPS(8) LMBENCH PAR_OPS(8) NAME par_ops - basic CPU operation parallelism SYNOPSIS par_ops [ -W <warmups> ] [ -N <repetitions> ] DESCRIPTION par_ops measures the available parallelism for basic CPU operations, such as integer ADD. Results are reported as the average operation latency di- vided by the minimum average operation latency across all levels of paral- lelism. 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. SEE ALSO lmbench(8), lat_ops(8), par_mem(8).
