Driven by the rapid hardware development of parallel CPU/GPU architectures, we have witnessed emerging relational query processing techniques and implementations on those parallel architectures. However, most of those implementations are not portable across different architectures, because they are usually developed from scratch and target at a specific(More)
Recently, there have been some emerging processor designs that the CPU and the GPU (Graphics Processing Unit) are integrated in a single chip and share Last Level Cache (LLC). However, the main memory bandwidth of such coupled CPU-GPU architectures can be much lower than that of a discrete GPU. As a result, current GPU query co-processing paradigms can(More)
Architecture designers tend to integrate both CPU and GPU on the same chip to deliver energy-efficient designs. To effectively leverage the power of both CPUs and GPUs on integrated architectures, researchers have recently put substantial efforts into co-running a single application on both the CPU and the GPU of such architectures. However, few studies(More)
MapReduce, originally developed by Google for search applications, has recently become a popular programming framework for parallel and distributed environments. This paper presents an energy-efficient architecture design for MapReduce on Field Programmable Gate Arrays (FPGAs). The major goal is to enable users to program FPGAs with simple MapReduce(More)
Architecture designers tend to integrate both CPUs and GPUs on the same chip to deliver energy-efficient designs. It is still an open problem to effectively leverage the advantages of both CPUs and GPUs on integrated architectures. In this work, we port 42 programs in Rodinia, Parboil, and Polybench benchmark suites and analyze the co-running behaviors of(More)
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(More)
Environmental problems have attracted increasing attention, yet individuals' connectedness to nature remains a significant concern for potential solutions to these problems. In this article, we propose a novel method to promote connectedness to nature: mindful learning. One hundred and thirty-four students participated in the experiment. First, baseline(More)
SAP Event Stream Processor (ESP) platform aims at delivering real-time stream processing and analytics in many time-critical areas such as Capital Markets, Internet of Things (IoT) and Data Center Intelligence. SAP ESP allows users to realize complex event processing (CEP) in the form of pattern queries. In this paper, we present MOTTO – a(More)
