04.11.2013: "Waste Not, Want Not - Efficient Co-Processing of Relational Data" (Holger Pirk, CWI Amsterdam) at 16:00 in Room EN-719

The variety of memory devices in modern computer systems holds
opportunities as well as challenges for data management systems. In
particular, the exploitation of Graphics Processing Units (GPUs) and
their fast memory has been studied quite intensively. However, current
approaches treat GPUs as systems in their own right and fail to
provide a generic strategy for efficient CPU/GPU cooperation. We
propose such a strategy for relational query processing: calculating
an approximate result based on lossily compressed, GPU-resident data
and refining the result using residuals, i.e., the lost data, on the
CPU.
