Chebyshev preconditioners are implemented by the IFPACK library by class Ifpack_Chebyshev, whose documentation is available here.
Typically, these preconditioners are used for symmetric and positive definite matrices. If you want to analyze the performances of this preconditioner, first click on Chebyshev Preconditioners to visualize the list of parameters, then set Analyze Chebyshev Preconditioners to Yes. The only parameter you have to select is the degree of the Chebyshev polynomial.
