    A computer system can be partitioned into hardware and the software executing on that hardware. The hardware consists of processor(s), memory, and "everything else". The "everything else" we generally combine under the umbrella "I/O, whose job it is to manage the availability of information to and from the processor(s) and memory". That information comes from storage devices, networks, and nonstor... View full abstract»

    Although disk storage densities are improving impressively (60% to 130% compounded annually), performance improvements have been occurring at only about 7% to 10% compounded annually over the last decade. As a result, disk system performance is fast becoming a dominant factor in overall svstem behavior. Naturally, researchers want to improve overall I/O performance, of which a large component is t...

    As the performance of other system components continues to improve rapidly, storage subsystem performance becomes increasingly important. Storage subsystem performance and reliability can be enhanced by logically grouping multiple disk drives into disk arrays. Array data organizations are defined by their data distribution schemes and redundancy mechanisms. The various combinations of these two co... View full abstract»

    I/O subsystem manufacturers attempt to reduce latency by increasing disk rotation speeds, incorporating more intelligent disk scheduling algorithms, increasing I/O bus speed, using solid-state disks, and implementing caches at various places in the I/O stream. In this article, we examine the use of caching as a means to increase system response time and improve the data throughput of the disk subs... View full abstract»

  • A systematic approach to host interface design for high-speed networks

    Optical fiber has made it possible to build networks with link speeds of over a gigabit per second; however, these networks are pushing end-systems to their limits. For high-speed networks (100 Mbits per second and up), network throughput is typically limited by software overhead on the sending and receiving hosts. Minimizing this overhead improves application-level latency and throughput and redu... View full abstract»

    Over the past two decades (1974-94), advances in semiconductor and integrated circuit technology have fuelled the drive toward faster, ever more efficient computational machines. Today, the most powerful supercomputers can perform computation at billions of floating-point operations per second (gigaflops). This increase in capability is intensifying the demand for even more powerful machines. Comp... View full abstract»

  • I/O issues in a multimedia system

    Publication Year: 1994, Page(s):69 - 74

    In future computer system design, I/O systems will have to support continuous media such as video and audio, whose system demands are different from those of data such as text. Multimedia computing requires us to focus on designing I/O systems that can handle real-time demands. Video- and audio-stream playback and teleconferencing are real-time applications with different I/O demands. We primarily... View full abstract»

    The authors introduce an application-level I/O facility, the Alloc Stream Facility, that addresses three primary goals. First, ASF addresses recent computing substrate changes to improve performance, allowing applications to benefit from specific features such as mapped files. Second, it is designed for parallel systems, maximizing concurrency and reporting errors properly. Finally, its modular an... View full abstract»

    New I/O devices with data rates ranging from 10 to 100 Mbytes per second are becoming available for personal computers and workstations. Along with continual improvements in processor, memory, and bus technology, these devices have enabled I/O-intensive applications for desktop computing that require input, processing, and output of very large amounts of data. We focus on an important aspect of op... View full abstract»
