In recent years, a new breed of non-uniform memory access (NUMA) systems has emerged: multi-socket servers of multicores. This paper makes the case that data management systems need to employ designs that take into consideration the characteristics of modern NUMA hardware. To prove our point, we focus on a primitive that is used as the building block of numerous data management operations: data shuffling. We perform a comparison of different data shuffling algorithms and show that a näıve data… CONTINUE READING
