Description

We describe a little in detail some techniques used in the calculation of
4-loop QED contributions to some quantities like g-2,
slope of the Dirac form factor, renormalization constants;
in particular, some different approaches to the parallelization of some
parts of the calculations. Some recent results will be also presented.
