Institution Background

 Poznan Supercomputing and Networking Center (PSNC), affiliated to the Institute Bioorganic Chemistry of Polish Academy of Sciences, is one of the leading research an computing centres in Poland. PSNC focuses on using, innovating and providing HPC, grid, cloud, portal and network technologies to enable advances in science and engineering. It hires around 300 people and is organised into 4 main technical departments: Application, Supercomputing, Network Services, and Networking Department. PSNC is a coordinator of PIONIER ­ the Polish Optical Network and as such is a partner of the GEANT network. It also operates one of 5 national HPC centres in Poland. In addition to operation and providing the advance infrastructure PSNC has contributed to a large number of national and EU­funded projects.


Research Group Background

 The Application Department at PSNC concentrates on methods and technologies for advanced applications, large-scale computing, resource management in distributed systems, visualization and new user’s interfaces, and energy-efficient systems.

The department has been involved in a large number of research projects including GridLab (as a coordinator), CoreGrid, inteliGrid, QoSCoSGrid, BREIN, HPC­Europa, AirProm and many others. It led the FP7 CoolEmAll project that aimed at improving energy efficiency of data centres. The department also represented Poland in the management committees of the European COST actions: IC0804 – Energy Efficiency in Large Scale Distributed Systems, and IC0805 – Open European Network for High Performance Computing on Complex Environments.

Application department has an experience in implementation of demanding applications in HPC domain, especially in computational biology, computer tomography, computational fluid dynamics in porous media, quantum chemistry, and others. For some of these applications fast implementations for GPGPU accelerators have been developed. The energy-efficient technologies team focuses on energy-efficient resource management, modelling of application energy efficiency, and simulation of energy and thermal aspects of computing.


Dr. Ariel Oleksiak works in the Applications Department at Poznan Supercomputing and Networking Center since 2002. He received his M.Sc. degree in Computer Science, Intelligent Decision Support Systems, from the Poznań University of Technology, Poland in 2001, and PhD in Computer Science from the same institution in 2009. Since 2008 he has been a deputy head of the department and now leads an energy-efficiency technologies team. His research interests include mainly resource management, scheduling, simulations, and performance analysis in distributed computing systems with a special focus on energy efficiency issues. He is an author of many publications in international scientific journals, books, and conferences. He has actively contributed to many research projects such as GridLab, HPC-Europa, QosCosGrid, BREIN, AirProm, and FiPS. He was a project coordinator of the EU-funded CoolEmAll project dealing with energy-efficiency of data centres. He also was a member of the management committee of the European COST Action IC0804: Energy Efficiency in Large Scale Distributed Systems. Currently he is a member in COST Action IC1305 on Sustainable Ultrascale Computing where he is a chair of the energy-efficiency working group.
