Acceleration beyond lowest order event generation. An outlook on further parallelism within MadGraph5_aMC@NLO / Wettersten, Zenny (CERN ; Vienna, OAW) ; Mattelaer, Olivier (Louvain U., CP3) ; Roiser, Stefan (CERN) ; Schöfbeck, Robert (Vienna, OAW) ; Valassi, Andrea (CERN)
An important area of high energy physics studies at the Large Hadron Collider (LHC) currently concerns the need for more extensive and precise comparison data. Important tools in this realm are event reweighing and evaluation of more precise next-to-leading order (NLO) processes via Monte Carlo event generators, especially in the context of the upcoming High Luminosity LHC.

Madgraph5_aMC@NLO on GPUs and vector CPUs Experience with the first alpha release / Hageboeck, Stephan (CERN) ; Childers, Taylor (Argonne (main)) ; Hopkins, Walter (Argonne (main)) ; Mattelaer, Olivier (Cathol. U. Louvain (main)) ; Nichols, Nathan (Argonne (main)) ; Roiser, Stefan (CERN) ; Teig, Jørgen (CERN) ; Valassi, Andrea (CERN) ; Vuosalo, Carl (U. Wisconsin, Madison (main)) ; Wettersten, Zenny (CERN)
Madgraph5_aMC@NLO is one of the most-frequently used Monte-Carlo event generators at the LHC, and an important consumer of compute resources. The software has been reengineered to maintain the overall look and feel of the user interface while speeding up event generation on CPUs and GPUs. [...]

Simplifying QCD event generation with chirality flow, reference vectors and spin directions / Boman, Emil (Lund U.) ; Lifson, Andrew (Lund U.) ; Sjodahl, Malin (Lund U.) ; Warnerbring, Adam (Siegen U.) ; Wettersten, Zenny (CERN ; Vienna, OAW)
The chirality-flow formalism, combined with good choices of gauge reference vectors, simplifies tree-level calculations to the extent that it is often possible to write down amplitudes corresponding to Feynman diagrams immediately. It has also proven to give a very sizable speedup in a proof of concept implementation of massless tree-level QED in MadGraph5_aMC@NLO. [...]
