Based on OpenBenchmarking.org data, the selected test / test configuration (clpeak - OpenCL Test: Single-Precision Float) has an average run-time of 2 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
