Accelerator-based systems are making rapid inroads into becoming platforms of choice for high end cloud services. There is a need therefore, to move from the current model in which high performance applications explicitly and programmatically select the GPU devices on which to run, to a dynamic model where GPUs are treated as first class schedulable(More)
While GPUs have become prominent both in high performance computing and in online or cloud services, they still appear as explicitly selected 'devices' rather than as first class schedulable entities that can be efficiently shared by diverse server applications. To combat the consequent likely under-utilization of GPUs when used in modern server or cloud(More)
Current silicon test methods are highly effective at sensitizing and propagating most electrical faults. Unfortunately, with ever increasing chip complexity and shorter time-to-market windows, an increasing number of faults escape undetected. To address this problem, we propose a novel technique to help identify hard-to-find electrical faults that are not(More)
Recent work on real-world graph analytics has sought to leverage the massive amount of parallelism offered by GPU devices, but challenges remain due to the inherent irregularity of graph algorithms and limitations in GPU-resident memory for storing large graphs. We present GraphReduce, a highly efficient and scalable GPU-based framework that operates on(More)
—The conflicting yet increasing demand for high performance and low power in multi-functional chips has pushed techniques for power reduction to the forefront of VLSI design. Although recent developments have automated most of the low power implementations, designers often manually modify the circuit in order to achieve further power savings. This human(More)
Exponential increase of online data and a corresponding growth of data-centric applications (Big Data analytics) forces system architects to revisit assumptions and requirements of the future system design. New non-volatile memory (NVM) technologies, such as Phase-Change Memory (PCM) and HP Memristor offer significantly improved latency and power efficiency(More)
