In this talk I will show how hardware acceleration techniques (in particular GPU computing) can be very beneficial to particle physics problems. From Monte Carlo calculations to PDF fitting. Some of the GPU-capable tools that will be mentioned are VegasFlow, a novel implementation of the Vegas algorithm targeting highly parallelizable scenarios, capable to offload parts of the calculation to hardware accelerators such as GPUs offering a massive speed-up with respect to traditional CPU-based Monte Carlo simulations and which has been used in the Madflow plugin of the well known MG5_aMC@NLO; pdfflow, for PDF interpolation in GPUs and n3fit, the fitting framework of the NNPDF collaboration. All software presented in this talk is public and open source.
