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.
