To translate the collisions inside the Belle II experiment into physics results, the information obtained by each component of the detector should be stored and processed. Belle II is expected to produce tens of peta-bytes of real and simulated data per year. This is equivalent to hundreds of thousands of CDs being written everyday.
The computing system plays a key role for the success of the experiment, managing the data of the events to be easily access and analyzed by the researchers.
In order to process these large-scale data and provide the physics results in a timely fashion, we adopt existing distributed computing technologies such as “GRID” and “Cloud”, connecting the computing resources of collaborating institutes in the world via high speed networks.
