    Evaluating the Effectiveness of Model-Based Power Characterization

    Accurate power characterization is important in computing platforms for several reasons ranging from power-aware adaptation to power provisioning. Power characterization is typically obtained through either direct measurements enabled by physical instrumentation or modeling based on hardware performance counters. The authors show, however, that linear-regression based modeling techniques commonly used in...

    TritonSort: A Balanced Large-Scale Sorting System

    The authors present TritonSort, a highly efficient, scalable sorting system. It is designed to process large datasets, and has been evaluated against as much as 100 TB of input data spread across 832 disks in 52 nodes at a rate of 0.916 TB/min. When evaluated against the annual Indy GraySort...

    Efficiently Measuring Bandwidth at All Time Scales

    The need to identify correlated traffic bursts at various, and especially fine-grain, time scales has become pressing in modern data centers. The combination of Gigabit link speeds and small switch buffers have led to "Microbursts", which cause packet drops and large increases in latency. The paper describes the design and...

    Understanding the Role of Buildings in a Smart Microgrid

    A 'Smart microgrid' refers to a distribution network for electrical energy, starting from electricity generation to its transmission and storage with the ability to respond to dynamic changes in energy supply through co-generation and demand adjustments. At the scale of a small town, a microgrid is connected to the wide-area...

    SPAIN: COTS Data-Center Ethernet for Multipathing Over Arbitrary Topologies

    Operators of data centers want a scalable network fabric that supports high bisection bandwidth and host mobility, but which costs very little to purchase and administer. Ethernet almost solves the problem it is cheap and supports high link bandwidths but traditional Ethernet does not scale, because its spanning-tree topology forces...

    Integrating Embedded Computing Systems into High School and Early Undergraduate Education

    Early exposure to embedded computing systems is crucial for students to be prepared for the embedded computing demands of today's world. Unfortunately, this exposure often comes too late in the curricula to make a meaningful impact. This paper describes the experience with integrating embedded computing systems education into high school...
