  Standard methods for higher-order calculations of QCD cross sections in
hadron-induced collisions are time-consuming. The fastNLO project uses
multi-dimensional interpolation techniques to convert the convolutions of
perturbative coefficients with parton distribution functions and the strong
coupling into simple products. By integrating the perturbative coefficients for
a given observable with interpolation kernels, fastNLO can store the results of
the time-consuming folding integrals in tables, which subsequently are used for
very fast rederivations of the same observable for arbitrary parton
distribution functions, different scale choices, or alpha_s(M_Z). Various
tables with code for their evaluation are available for numerous jet
measurements at the LHC, the TeVatron, and HERA. FastNLO is used in
publications of experimental results by the ATLAS, CMS, CDF, D0, and H1
collaborations, and in all recent global PDF analyses by MSTW, CTEQ, and NNPDF.
This article focuses on developments implemented in the new version 2 of
fastNLO, enhancing and broadening its functionality.
