+
+
+
+
+
+
| int bind_to_cpu | +( | +const unsigned | +cpu | ) | ++ |
+
+

+- Parameters
-
+
+
+[in] cpu Core number.
+
- Returns
- 0 on success, -1 otherwise.

+
+
+
+
+
+
| std::pair<double, double> calculate_statistics | +( | +const std::vector< long > | +values | ) | ++ |
+
+
+Calculate the mean and variance from the result of the run_benchmark.
+- Parameters
-
+
+
+[in] values Vector with result values.
+
- Returns
- std::pair where the first element is mean and the second one is standard deviation.
- Note
- It's not a general mean/stddev function it only works properly when feed with data from the benchmark function.

+- Parameters
-
+
+
+[in] number Positive integer value.
+
- Returns
- Vector with the sorted integer numbers between 0 and number - 1.
