MadGraph provides a world-wide on-line service for the generation of events relevant for studies at present and future high-energy colliders. The capabilities of the current version 5 include: event generation via the web for any Standard Model process as well as for new physics models via FeynRules; fully-staged simulation chain, from model building to detector simulation; multi-jet sample production and merging; interfaces with the software frameworks of the main experiments at the LHC and the possibility of event generation over the computing GRID. Version 5 now distributes publicly the automatic computation of loop amplitudes (MadLoop), the combination with the real corrections (MadFKS) and the automatic interface via the MC@NLO method (aMC@NLO) to Herwig and Pythia for parton showering and hadronization.
