Περίληψη: Processing of large collections of real-world data series is nowadays one of the most challenging and critical problems for a wide range of diverse application domains, including finance, seismology and other earth sciences, astrophysics, neuroscience, engineering, etc. Due to the unprecedented growth in size that data series collections experience nowadays, traditional, serial-execution data series indexing technologies are rendered inadequate. Thus, one of the most pressing issues in data series processing is achieving enhanced performance and high scalability. This talk will present the first concurrent data series indexing solutions that are designed to inherently take advantage of modern hardware, in order to accelerate data series processing times for both on-disk and in-memory data. In particular, we will present a collection of algorithms that utilize multi-core and SIMD architectures, as well as Graphics Processing Units (GPUs) to tackle the performance and scalability goals. The algorithms to present are orders of magnitude faster than the state-of-the-art solutions for both disk-resident and in-memory data.
