Offloading to hardware components that support the primary task of a system enables separation of concerns and allows both the primary and offloaded components of a system to be easy to understand, manage, and evolve independent of other components. In this dissertation, we explore the software mechanisms required to effectively offload functionality to idle processing elements. We present the design, implementation, and evaluation of three system architectures -- TCPServers, Orion, and FileWall, which offload functionality for improving performance (TCPServers), improving availability (Orion), and for extending functionality (FileWall). We explore software mechanisms to offload functionality to a subset of processors in an Symmetric Multiprocessor (SMP) system, a programmable network interface, and an interposing network middlebox to realize the three system architectures. TCPServers is a system architecture that offloads network processing to a subset of processors in an SMP system. Network processing imposes direct and indirect overheads on server systems. It directly affects system performance since it executes at a higher priority than application tasks and prevents other components of the system from executing simultaneously on the processors. It indirectly affects performance by causing cache pollution and Translation Lookaside Buffer (TLB) flushes, which lead to degraded memory system performance. Through offloading, TCPServers isolates the network processing and eliminates the direct overheads. We also present mechanisms for increasing network stack concurrency and connection scheduling, which significantly improve the performance in a multi-threaded network stack. Orion is a system architecture that enables Remote Healing, where the monitoring and healing actions are performed externally, by offloading such functionality to external hardware. Fine grained monitoring of computer systems for performance anomalies, intrusion detection, and failure detection imposes significant overhead on the target system. Performance critical systems, where such fine grained monitoring is essential, cannot be subjected to these overheads. Orion offloads the healing functionality to a programmable network interface, which provides an alternate path to the memory of the target system. Using Orion, monitoring and healing actions can be performed nonintrusively, without involving the processors of the target system. We present the design and implementation of mechanisms for remote monitoring and remote repair of damaged OS state using Orion. FileWall is a system architecture that enables extension of network file system functionality. Network file system evolution is constrained by the tight binding between clients and servers. This binding limits the evolution of file system protocols and hinders deployment of file system or protocol extensions. For example, current network file systems have limited support for implementing file access policies. We propose message transformation as a mechanism to separate the client and server systems for protocol enhancement. FileWall offloads message transformation and policy enforcement to an interposing network element on the client-server path. We have used FileWall to implement file access policies and present experimental results showing policy enforcement at FileWall imposes minimal overheads on the base file system protocol. The main conclusion of our research is that system architectures based on functionality offloading can be realized simply and effectively through efficient software mechanisms, using only commodity off the shelf hardware. With the availability of resources at idle processing cores in a multiprocessor system, intelligent peripherals, and unused nodes in a cluster, offloading is a practical solution for improving performance and introducing new functionality in computer systems and networks.

High Performance Embedded Computing written by Luis Miguel Pinho and has been published by CRC Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2022-09-01 with Computers categories.

Nowadays, the prevalence of computing systems in our lives is so ubiquitous that we live in a cyber-physical world dominated by computer systems, from pacemakers to cars and airplanes. These systems demand for more computational performance to process large amounts of data from multiple data sources with guaranteed processing times. Actuating outside of the required timing bounds may cause the failure of the system, being vital for systems like planes, cars, business monitoring, e-trading, etc. High-Performance and Time-Predictable Embedded Computing presents recent advances in software architecture and tools to support such complex systems, enabling the design of embedded computing devices which are able to deliver high-performance whilst guaranteeing the application required timing bounds. Technical topics discussed in the book include:  Parallel embedded platforms Programming models Mapping and scheduling of parallel computations Timing and schedulability analysis Runtimes and operating systemsThe work reflected in this book was done in the scope of the European project P SOCRATES, funded under the FP7 framework program of the European Commission. High-performance and time-predictable embedded computing is ideal for personnel in computer/communication/embedded industries as well as academic staff and master/research students in computer science, embedded systems, cyber-physical systems and internet-of-things.

Perceptual Learning written by Kevin Connolly and has been published by Oxford University Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2019-01-16 with Philosophy categories.

Experts from wine tasters to radiologists to bird watchers have all undergone perceptual learning-long-term changes in perception that result from practice or experience. Philosophers have been discussing such cases for centuries, from the 14th-century Indian philosopher Vedanta Desika to the 18th-century Scottish philosopher Thomas Reid, and into contemporary times. This book uses recent evidence from psychology and neuroscience to show that perceptual learning is genuinely perceptual, rather than post-perceptual. It also offers a taxonomy for classifying cases in the philosophical literature. In some cases, perceptual learning involves changes in how one attends; in other cases, it involves a learned ability to differentiate two properties, or to perceive two properties as unified. Connolly uses this taxonomy to rethink several domains of perception in terms of perceptual learning, including multisensory perception, color perception, and speech perception. As a whole, the book offers a theory of the function of perceptual learning. Perceptual learning embeds into our quick perceptual systems what would be a slower task were it to be done in a controlled, cognitive manner. A novice wine taster drinking a Cabernet Sauvignon might have to think about its features first and then infer the type of wine, while an expert can identify it immediately. This learned ability to immediately identify the wine enables the expert to think about other things like the vineyard or the vintage of the wine. More generally, perceptual learning serves to free up cognitive resources for other tasks. This book offers a comprehensive empirically-informed account, and explores the nature, scope, and theoretical implications of perceptual learning.
