    Octopus-Man: QoS-Driven Task Management for Heterogeneous Multicores in Warehouse-Scale Computers

    Heterogeneous multi-core architectures have the potential to improve energy efficiency by integrating power-efficient wimpy cores with high-performing brawny cores. However, it is an open question as how to deliver energy reduction while ensuring the Quality of Service (QoS) of latency-sensitive web services running on such heterogeneous multicores in Warehouse Scale...

    Adrenaline: Pinpointing and Reining in Tail Queries with Quick Voltage Boosting

    Reducing the long tail of the query latency distribution in modern warehouse scale computers is critical for improving performance and quality of service of workloads such as web search and mem-cached. Traditional turbo boost increases a processor's voltage and frequency during a coarse grain sliding window, boosting all queries that...

    Protean Code: Achieving Near-Free Online Code Transformations for Warehouse Scale Computers

    Rampant dynamism due to load fluctuations, co-runner changes and varying levels of interference poses a threat to application Quality of Service (QoS) and has limited the authors' ability to allow co-locations in modern Warehouse Scale Computers (WSCs). Instruction set features such as the non-temporal memory access hints found in modern...

    SMiTe: Precise QoS Prediction on Real-System SMT Processors to Improve Utilization in Warehouse Scale Computers

    One of the key challenges for improving efficiency in Warehouse Scale Computers (WSCs) is to improve server utilization while guaranteeing the Quality of Service (QoS) of latency-sensitive applications. To this end, prior paper has proposed techniques to precisely predict performance and QoS interference to identify 'Safe' application co-locations. However, such...

    HaPPy: Hyperthread-Aware Power Profiling Dynamically

    Quantifying the power consumption of individual applications co-running on a single server is a critical component for software-based power capping, scheduling and provisioning techniques in modern datacenters. However, with the proliferation of hyper-threading in the last few generations of server-grade processor designs, the challenge of accurately and dynamically performing this...

    BlockChop: Dynamic Squash Elimination for Hybrid Processor Architecture

    Hybrid processors are HW/SW co-designed processors that leverage blocked-execution, the execution of regions of instructions as atomic blocks, to facilitate aggressive speculative optimization. As the authors move to a multi-core hybrid design, fine grained conflicts for shared data can violate the atomicity requirement of these blocks and lead to expensive...

    Performance Analysis of Thread Mappings with a Holistic View of the Hardware Resources

    With the shift to chip multiprocessors, managing shared resources has become a critical issue in realizing their full potential. Previous research has shown that thread mapping is a powerful tool for resource management. However, the difficulty of simultaneously managing multiple hardware resources and the varying nature of the workloads has...

    Heterogeneity in "Homogeneous" Warehouse-Scale Computers: A Performance Opportunity

    The class of modern datacenters recently coined as "Warehouse Scale Computers" (WSCs) has traditionally been embraced as homogeneous computing platforms. However, due to frequent machine replacements and upgrades, modern WSCs are in fact composed of diverse commodity microarchitectures and machine configurations. Yet, current WSCs are designed with an assumption of...

    Scenario Based Optimization: A Framework for Statically Enabling Online Optimizations

    Online optimization allows the continuous restructuring and adaptation of an executing application using live information about its execution environment. The further advancement of performance monitoring hardware presents new opportunities for online optimization techniques. While managed runtime environments lend themselves nicely to online and dynamic optimizations, such techniques remain difficult to...

    A Static Analysis for Automatic Detection of Atomicity Violations in Java Programs

    Multithreaded programs can have subtle errors that result from undesired interleavings of concurrent threads. A common technique to prevent these errors is to ensure that certain blocks of code are atomic. A block of code is atomic if every execution is equivalent to a serial execution in which no other...

    The Emerging Revolution In Emissions Trading Policy

    Emissions trading policies initially relied on "Squatter's rights" principles granting emissions allowances to existing polluters for free. Recently, however, policy designers have largely abandoned this approach, requiring polluters to buy allowances from the public through auctions. Given the high financial stakes, this is a momentous shift. Given how skeptical experts...

    Financing Development Of Drugs And Vaccines For Neglected Diseases

    New drugs and vaccines could save millions of lives in the developing world. But drug and vaccine development is expensive, and many of these badly needed health technologies promise markets too small to interest the for-profit pharmaceutical industry, which dominates later stages of research and development. A number of new...
