    Coherent Network Interfaces for Fine-Grain Communication

    Historically, processor accesses to memory-mapped device registers have been marked uncachable to insure their visibility to the device. The ubiquity of snooping cache coherence, however, makes it possible for processors and devices to interact with cachable, coherent memory operations. Using coherence can improve performance by facilitating burst transfers of whole...

    Distribution-Based Query Scheduling

    Query scheduling, a fundamental problem in database management systems, has recently received a renewed attention, perhaps in part due to the rise of the \"Database as a Service\" (DaaS) model for database deployment. While there has been a great deal of work investigating different scheduling algorithms, there has been comparatively...

    Online, Asynchronous Schema Change in F1

    The authors introduce a protocol for schema evolution in a globally distributed database management system with shared data, stateless servers, and no global membership. Their protocol is asynchronous - it allows different servers in the database system to transition to a new schema at different times - and online -...

    High-Throughput GPU-Based LDPC Decoding

    Low-Density Parity-Check (LDPC) code is a linear block code known to approach the Shannon limit via the iterative sum-product algorithm. LDPC codes have been adopted in most current communication systems such as DVB-S2, WiMAX, WI-FI and 10GBASE-T. LDPC for the needs of reliable and flexible communication links for a wide...

    Multirate Media Streaming Using Network Coding

    Multimedia data transfers typically involve large volumes of data. Multirate multicast transmissions using layered source coding are generally used to deliver data streams to heterogeneous receivers. Network coding has been envisioned to increase throughput and deliver higher data rates than conventional source coding or no coding. The paper proposes a...

    SymDrive: Testing Drivers without Devices

    Device drivers are critical to operating-system reliability, yet are difficult to test and debug. They run in kernel mode, which prohibits the use of many runtime program-analysis tools available for user-mode code, such as Val-grind. Their need for hardware can prevent testing altogether: over two dozen driver Linux and FreeBSD...

    Automated Concurrency-Bug Fixing

    Concurrency bugs are widespread in multithreaded programs. Fixing them is time-consuming and error-prone. The authors present CFix, a system that automates the repair of concurrency bugs. CFix works with a wide variety of concurrency-bug detectors. For each failure-inducing interleaving reported by a bug detector, CFix first determines a combination of...

    Fast Peak-to-Peak Restart for SSD Buffer Pool Extension

    A promising usage of Flash SSDs in a DBMS is to use it to extend the main memory buffer pool by caching in the SSD selected pages that are evicted from the buffer pool. These schemes have been shown to produce big performance gains in the steady state. Simple methods...

    On the Dispersions of Three Network Information Theory Problems

    The authors characterize fundamental limits for distributed lossless source coding (the Slepian-Wolf problem), the multiple-access channel and the asymmetric broadcast channel in the finite blocklength setting. For the Slepian-Wolf problem, they introduce a fundamental quantity known as the entropy dispersion matrix, which is analogous to the scalar dispersion quantities that...

    Finite Blocklength Slepian-Wolf Coding

    The authors characterize the fundamental limits for distributed lossless source coding (Slepian-Wolf) in the finite blocklength regime. They introduce a fundamental quantity known as the entropy dispersion matrix, which is analogous to scalar dispersion quantities. They show that if this matrix is positive-definite, the optimal rate region under the constraint...

    Canonical Estimation in a Rare-Events Regime

    The authors propose a general methodology for performing statistical inference within a 'rare-events regime' that was recently suggested by Wagner, Viswanath and Kulkarni. Their approach allows one to easily establish consistent estimators for a very large class of canonical estimation problems, in a large alphabet setting. These include the problems...

    When Free Is Not Really Free: What Does It Cost to Run a Database Workload in the Cloud?

    One of the greatest hurdles associated with deploying traditional on-site Relational DataBase Management Systems (RDBMSs) is the overall complexity of choosing, configuring, and maintaining the RDBMS as well as the server it operates on. The current computing trend towards cloud-based Database-as-a-Service (DaaS) as an alternative to traditional on-site Relational DataBase...

    Rethinking Query Processing for Energy Efficiency: Slowing Down to Win the Race

    The biggest change in the TPC benchmarks in over two decades is now well underway - namely the addition of an energy efficiency metric along with traditional performance metrics. This change is fueled by the growing, real, and urgent demand for energy-efficient database processing. Database query processing engines must now...

    Estimating The Effects Of Dormitory Living On Student Performance

    Many large universities require freshman to live in dormitories on the basis that living on campus leads to better classroom performance and lower drop out incidence. Large universities also provide a number of academic services in dormitories such as tutoring and student organizations that encourage an environment conducive to learning....

    Password Authentication from a Human Factors Perspective: Results of a Survey among End-Users

    Considering that many organizations today are extremely dependent on information technology, Computer and Information Security (CIS) has become a critical concern from a business viewpoint. CIS is concerned with protecting the confidentiality, integrity, accessible information, when using computer systems. Much research has been conducted on CIS in the past years....

    Discovery-Driven Graph Summarization

    Large graph datasets are ubiquitous in many domains, including social networking and biology. Graph summarization techniques are crucial in such domains as they can assist in uncovering useful insights about the patterns hidden in the underlying data. One important type of graph summarization is to produce small and informative summaries...

    Complexity of Component-Based Development of Embedded Systems

    The paper discusses complexity of Component-Based Development (CBD) of embedded systems. Although CBD has its merits, it must be augmented with methods to control the complexities that arise due to resource constraints, timeliness, and run-time deployment of components in embedded system development. Software component specification, system-level testing, and run-time reliability...
