Thermostats are used in molecular-dynamics calculations within the NVT ensemble and NpT ensemble in order to apply a certain temperature to the ionic degrees of freedom.

Choose between stochastic thermostats:

and deterministic thermostats:

The following table gives an overview of the possible combination of ensembles and thermostats in VASP:
