MEMOCODE 2015 design contest: Continuous skyline computation

The skyline query operation (also called the “maximum vector problem”) is used to identify potentially interesting or useful data points in large sets of multi-dimensional data. When the data change over time (through addition and subtraction of points), this is called the “continuous skyline” query. The 2015 MEMOCODE Design Contest problem is to implement a system to efficiently compute the continuous skyline of dynamic data. Contestants were given one month to develop a system to perform the skyline query, aiming to maximize performance or cost-adjusted performance. Teams were encouraged to consider a variety of computational targets including CPUs, FPGAs, and GPGPUs. The two winning teams, which have been invited to contribute papers describing their techniques, combined careful algorithmic and implementation optimizations; both implemented the system on multicore CPUs.
