Driven by the rapidly increasing demand for handling real-time data streams, many data stream processing (DSP) systems have been proposed. Regardless of the different architectures of those DSP systems, they are mostly aiming at scaling out using a cluster of commodity machines and built around a number of key design aspects: a) pipelined processing with message passing, b) on-demand data parallelism,...
Recently, continuous 3D printing, a revolutionary branch of legacy additive manufacturing, has made its two-order time efficiency breakthrough in industrial manufacturing. As its manufacturing technique advances rapidly, the prefabrication to slice the 3D object into image layers becomes potential to impede further improvement of production efficiency. In this paper, we present two scalable and efficient...
Solid state drives (SSDs), or flash disks have been considered as ideal storage for various data-intensive workloads, because of the low random access latency and the intra-disk multi-chip parallelism. However, due to inherent nature of flash memories, update-intensive workloads cause the flash disk fragmented, and trigger costly internal activities such as cleaning and wear leveling. We use database...
