The DOME project, supported by grants from the Dutch Ministry of Economic Affairs and the Province of Drenthe, focuses on three main areas: Green Computing, Data & Streaming and Nano-photonics. It’s a close cooperation between ASTRON and the IBM Center for Exascale Technology. Data centers all over the world are confronted with an ever increasing demand of web and cloud services, like data analysis and search engines. To meet these challenges and to reduce the energy consumption at the same time, we have developed an extreme energy efficient and high density micro server within the DOME project. The micro server has the size of a cell phone and acts like a full-fledged server. The new micro server concept including a prototype were officially presented to Dutch SME companies, during the Micro Server Event in Dwingeloo, on April 14th, 2014. The reduction of energy consumption in large computer systems is crucial for the future SKA radio telescope and is also very important for data centers in general.
In 2015 we presented the water-cooled micro server at various conferences and events (IEEE SC, ISSCC and CEBIT). Three of our DOME partners (Philips Drachten, TU Eindhoven and Sensor City Assen) tested the application of the micro-server in 2015, in order to assess the competitiveness of the computing platform. Within Dome we have additionally developed a tool that studies the estimated power consumption and processing requirements of algorithms and computer architecture. This tool is being used in multiple SKA consortia now. All areas of research within DOME show promising results. They can lead to further reduction of the required computing power. Besides the power issues we have developed a new method to make pictures of the sky very efficiently. As a next step, the algorithm will be applied and verified on our LOFAR data. To let SME companies benefit from the new DOME technologies, we organized a Dome Users Platform Match Making Event in Dwingeloo, on October 29th, 2014.
