Description

We present a GPU-based parton level event generator for multi-jet events at the LHC.  The current implementation generates up to 10 jets with a possible vector boson.  At leading order the speed increase over a single core CPU is in excess of a factor of 500 using  a single desktop based NVIDIA Fermi GPU.   We will also present results for the next-to-leading order implementation.
