  In Run 1 of the Large Hadron Collider, software and computing was a strategic
strength of the Compact Muon Solenoid experiment. The timely processing of data
and simulation samples and the excellent performance of the reconstruction
algorithms played an important role in the preparation of the full suite of
searches used for the observation of the Higgs boson in 2012. In Run 2, the LHC
will run at higher intensities and CMS will record data at a higher trigger
rate. These new running conditions will provide new challenges for the software
and computing systems. Over the two years of Long Shutdown 1, CMS has built
upon the successes of Run 1 to improve the software and computing to meet these
challenges. In this presentation we will describe the new features in software
and computing that will once again put CMS in a position of physics leadership.
