The Compressed Baryonic Matter experiment (CBM) is one of the core experiments to be operated at the future FAIR accelerator complex in Darmstadt, Germany, from 2014 on. It will investigate heavy-ion collisions at moderate beam energies but extreme interaction rates, which give access to extremely rare probes such as open charm or charmonium decays near the production threshold. The high event rates combined with the high track multiplicities result in extreme data rates to be processed in an online first level event selection (FLES) in order to arrive at at a reasonable archival rate. Novel concepts for online data processing are necessary to cope with this environment. Even after efficient online event selection, a large data volume (several PB per runtime) will have to be made available for the offline analysis. Event reconstruction algorithms must be fast and precise in order to give access to the rare physics signals. In this presentation, we will discuss the requirements for CBM computing, both online and offline, and present the current status of the preparations, including the simulation and reconstruction framework and algorithms developed by now.
