Available in PDF, EPUB and Kindle. Book excerpt: Emerging high performance, high speed and scalable networks allow machines to access remote memory quicker than accessing disks. This paves way for coordinating the file caches of workstations in a distributed local area network, known as Cooperative Caching. This study introduces a novel cache architecture for cooperative caching called Reliable, Efficient and Distributed Cooperative Cache''. We present three algorithms - Server Logging, Client Logging and Peer Logging - that combine duplication with logging in order to improve the write performance of cooperative caching while ensuring the reliability of the data. We evaluate the performance of the logging algorithms using trace driven simulations. Several synthetic traces and two real world traces were used to measure the performance improvement obtained by the algorithms. The simulations indicate that the speedup obtained is as high as 10 compared to the baseline system. Based on the simulations, we conclude that the logging algorithms make complete use of the cooperative caching environment and provide better overall improvement by reducing the response time of write requests, improving individual client performance, minimizing the load on the server and ensuring reliability and availability of data.

Available in PDF, EPUB and Kindle. Book excerpt: Researches in the recent years have shown great improvement in the performance of network systems. High-speed, low-latency networks can achieve a high transfer rate at a low cost. This has lead to the popularity of Distributed systems built using low-cost PCs and high speed, scalable net-works. However, there lays a wide gap between the disk storage speed and the processor/memory speed which slows down the performance of the system. Efficient techniques have been developed to bridge this gap and improve the performance. Cooperative caching is one of the techniques em-ployed to improve the performance of a distributed system. Cooperative caching uses a small part of the cache memory of each client to form global cache which is used to cache the data blocks. This avoids unnecessary accesses to the disk, thus speeding up the read performance. The write performance issues are not handled by Cooperative caching. Use of a write-through cache for reliability slows down the write performance of the system. We propose a novel, reliable Cooperative Caching architecture, Distributed Efficient and Re-liable Cooperative Cache (DEFER Cache), which aims at improving the write performance. It extends the idea of cooperative caching to write operations. It combines duplication with logging to enhance the write performance and also provided increased reliability and data availability.

Available in PDF, EPUB and Kindle. Book excerpt: Computational Science is the scientific discipline that aims at the development and understanding of new computational methods and techniques to model and simulate complex systems. The area of application includes natural systems - such as biology environ mental and geo-sciences, physics, and chemistry - and synthetic systems such as electronics and financial and economic systems. The discipline is a bridge bet ween 'classical' computer science - logic, complexity, architecture, algorithm- mathematics, and the use of computers in the aforementioned areas. The relevance for society stems from the numerous challenges that exist in the various science and engineering disciplines, which can be tackled by advances made in this field. For instance new models and methods to study environmental issues like the quality of air, water, and soil, and weather and climate predictions through simulations, as well as the simulation-supported development of cars, airplanes, and medical and transport systems etc. Paraphrasing R. Kenway (R.D. Kenway, Contemporary Physics. 1994): 'There is an important message to scientists, politicians, and industrialists: in the future science, the best industrial design and manufacture, the greatest medical progress, and the most accurate environmental monitoring and forecasting will be done by countries that most rapidly exploit the full potential of computational science'. Nowadays we have access to high-end computer architectures and a large range of computing environments, mainly as a consequence of the enormous sti mulus from the various international programs on advanced computing, e.g.

Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2017 in the subject Computer Science - Applied, grade: 3.5, course: Assignment, language: English, abstract: From the recent studies we come to know that the cooperative caching can improve the performance of system in wireless P2P networks such as hoc networks and mesh networks do. Somehow these all very high level studies leave many design and implementation issues which are still unanswered. While by study it shows that cooperative caching not only reduce the overhead copying issue between the user space and the kernel space, but it also allow data pipelines for end to end delay reduction. While the chip multiprocessors systems have made the on-chip caches as a decisive recourse shared among co scheduled threads. Still there are many challenges with respect to design for limited bandwidth, increasing on-chip wire interruption and extra capability features. So effectively Cooperative cache can support minimizing average access of memory latency and inaccessibility of critical inter-thread interference. So Caching is the common technique used for improve the. Cooperative Cache approach is intended for the treatment of large video streams with on requires access. Day by day Mobile technology is coming around us. So for general this technology needs address of Internet Service Provider (ISP) for cross-domain traffic. So different researchers present's algorithms of the strategy that shows changes brought to the content center network protocol in to implement the method. As recent works on cooperative caching in networks technology like work on Content Center network also enables the manipulation of the cache resources of routers with new generation. For CRs mostly researcher proposed least recently Used (LRU) approach. Cooperative cache can improve accessibility of data objects in mobile ad hoc network, where a mobile host can communicate with any other system anywhere anytime. Cooperative caching in mobile technology brings reality with
