# Test descriptions

Several tests are built into the software. Each of these tests contains one or more sub-tests designed to exercise different aspects of your computer system. These tests can be run concurrently, with each test having its own window and using its own CPU thread or as individual tests. It is also possible to vary the load mix by increasing or decreasing the duty cycle for a particular test.

Each test keeps an error counter, a cycle counter and an operations counter. The significance of each of these counters is detailed with each test.

The following tests are currently available.
