  We present cross section predictions for squark and gluino production at the
LHC, in association with up to two additional hard jets. These cross sections
can be very large in comparison to the inclusive Born rates. Because hadron
collider experiments utilize hard jets in the reconstruction of cascade decays
or as a way to separate squark and gluino production, the understanding of
these processes is crucial. We show to what degree hard jet radiation can be
described by shower algorithms and point out how tuning these showers, for
example to top quark pair production, could help reduce theoretical
uncertainties for new physics searches at the LHC.
