Extreme Data Processing in Exascale Systems

Abstract. Extreme data refers to massive amounts of data that must be queried, communicated and analyzed in near real-time. Analyzing massive scientific data gathered in each second, mining huge sets of images in crisis management, or dealing with millions of social data posts for are few examples. Processing them on exascale systems requires new programming models. Data-aware basic operations for data-intensive applications supporting the scale use of a massive number of processing elements were introduced recently (a bird-view of these proposals will be presented in the talk). As follow ups, solutions for anomaly and event detections and monitoring in data processing were proposed (a focused view of these proposals will be provided in the talk). However, moving part of the data (pre-)processing out of the exascale system towards the edge of the network is another solution and techniques like transprecision computation or machine learning to adapt to the device capabilities are able to reduce the load for the exascale system.
