    Rapid Processing of Synthetic Seismograms Using Windows Azure Cloud

    Currently, numerically simulated synthetic seismograms are widely used by seismologists for seismological inferences. The generation of these synthetic seismograms requires large amount of computing resources, and the maintenance of these observed seismograms requires massive storage. Traditional high-performance computing platforms is inefficient to handle these applications because rapid computations are needed...

    Safe Transient Use of Local Storage for VM-Based Mobility

    This paper investigates the transient use of free local storage for improving performance in VM-based mobile computing systems. Many such systems boot from a portable storage device to create a "Zero-install" environment on a computer that is borrowed for temporary use. Unfortunately, consumer-grade portable storage devices are optimized for capacity...

    DIADS: A Problem Diagnosis Tool for Databases and Storage Area Networks

    Many enterprise environments have databases running on network-attached storage infrastructure (referred to as Storage Area Networks or SANs). Both the database and the SAN are complex subsystems that are managed by separate teams of administrators. As often as not, database administrators have limited understanding of SAN configuration and behavior, and...

    Exploiting the Interplay Between Memory and Flash Storage in Embedded Sensor Devices

    Although memory is an important constraint in embedded sensor nodes, existing embedded applications and systems are typically designed to work under the memory constraints of a single platform and do not consider the interplay between memory and flash storage. In this paper, the authors present the design of a memory-adaptive...

    Delay-Hiding Energy Management Mechanisms for DRAM

    Current trends in data-intensive applications increase the demand for larger physical memory, resulting in the memory subsystem consuming a significant portion of system's energy. Furthermore, data-intensive applications heavily rely on a large buffer cache that occupies a majority of physical memory. Subsequently, the authors are focusing on the power management...
