This is already the second time we have published the results of the annual work of our HPC (High Performance Computing) users. The current issue presents the results from 2011. Poznan Supercomputing and Networking Center has been providing computing power continuously since 1994. Since that time, the nature and way of sharing computing power has changed significantly. In addition to traditional grant applications that give users access to HPC resources in the country, there are also virtual organizations (VOs), for which PSNC made available its resources. The first virtual organizations appeared in 2007 within the framework of European projects: EGEE (Enabling Grids for E-sciencE, and WLCG (The Worldwide LHC Computing Grid, http://wlcg . /).
In 2011, virtual organizations used 7 million hours of CPU time (in comparison to 0.5 million hours of CPU in 2007) allocated by the queuing system, the record holder is ALICESGM (A Large Ion Collider Experiment At CERN LHC). HPC users have used 9 million CPU hours. The total of all users used 16 million hours allocated by the queuing system, and is an increase of 100% (in comparison to 2010) of the CPU time that was dedicated to HPC users.
