## Monitoring
`perfect` can monitor and record GPU activity.
See [examples/gpu_monitor.cu](examples/gpu_monitor.cu)
```c++
#include "perfect/cpu_monitor.hpp"
```
* `Monitor(std::ostream *stream)`: create a monitor that will write to `stream`.
* `void Monitor::start()`: start the monitor
* `void Monitor::stop()`: terminate the monitor
* `void Monitor::pause()`: pause the monitor thread
* `void Monitor::resume()`: resume the monitor thread
### CPU Turbo
`perfect` can enable and disable CPU boost through the Intel p-state mechanism or the ACPI cpufreq mechanism.
