Description

In this talk, I will review some of our experiences implementing the evaluation of multi-loop integrals and multi-loop amplitudes on GPUs using the sector decomposition method. I will highlight recent developments and how they have impacted the performance of this method and I will summarise some of the main lessons learned. Additionally, I will briefly comment on potential avenues/obstacles to utilising heterogeneous computing platforms for other numerical/semi-numerical approaches to evaluating Feynman Integrals and integral reduction.
