| Argument | Description | |
| -c <count> | Sets the operations per sample to <count> (default = 20). | |
| -s <samples> | Takes <samples> samples, each sample consisting of many operations (default = 10). | |
| -co <corr> | Sets the minimum correlation between samples for which to post an error. | |
| -m <maxTime> | Considers this test to fail if the median time per operation is greater than <maxTime> (default = none). | |
| -at <tol> | Sets the tolerance for automatic sampling to <tol> (default = 0.1). | |
| -na | Turns off automatic timing. | |
| -w <maxWindows> | Stops if times do not converge within <maxWindows> windows of automatic sampling (default = 10). | |
| -cc | Continually calibrates by measuring empty loop time before each sample. | |
| -t | Does not do timing tests; just executes one operation without timing |
