Description
I will briefly report on two distinct attempts to port on GPU an algorithm commonly used in the evaluation of radiative corrections to particle scattering processes:
1) the reconstruction of a rational function, useful in the exact numerical solution of the linear systems typically present in multi-loop calculations;
2) the generation of events via a parton-shower algorithm.
In both cases some interesting indications emerge, related to the logical mistakes that one should avoid in the parallelization of algorithms which originally are designed for sequential evaluation.
