TITLE: Big Data and Computing for the SKA Telescope

The Square Kilometer Array radio telescope, currently under design by institutions in 10 countries for deployment in remote deserts around 2022, will be a revolutionary scientific instrument to observe the universe. Ultra large HPC systems will transform a massive stream of antenna data -- as much as an exa-byte per day -- into scientific data placed into an archive for worldwide consumption. The steepest challenges include extreme parallelism in the algorithms and providing 200 PB/sec of memory bandwidth under strict power constraints. This presentation covers an overview of the the telescope and of the software and system architecture that is currently under development. [SLIDES]

Peter Braam is a scientist and entrepreneur focused on problems in large scale computing. Originally trained as a mathematician, he has worked at several academic institutions including Oxford, CMU and Cambridge. One of his startup companies developed the Lustre file system which is widely used. During the last few years he has focused on computing for the SKA telescope.
