Description
For more than a decade the current generation of fully automated,
matrix element generators has provided hard scattering events with
excellent flexibility and good efficiency. However, as recent studies
have shown, they are a major bottleneck in the established Monte Carlo
event generator toolchains. With the advent of the HL-LHC and ever
rising precision requirements, future developments will need to focus
on computational performance, especially at intermediate to large jet
multiplicities. We present a novel family of fast matrix
element algorithms that are amenable for GPU acceleration, making use
of modern, minimal color decompositions. Moreover, we discuss the
performance achieved for standard candle processes such as V+jets and
ttbar+jets production.
