This book was released on 1989 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: PLATINUM is an operating system kernel with a novel memory management system for Non-uniform Memory Access (NUMA) multiprocessor architectures. This memory management system implements a coherent memory abstraction. Coherent memory is uniformly accessible from all processors in the system. When used by applications coded with appropriate programming styles it appears to be nearly as fast as local physical memory and it reduces memory contention. Coherent memory makes programming NUMA multiprocessors easier for the user while attaining a level of performance comparable with hand-tuned programs. This paper describes the design of the PLATINUM memory management system with emphasis on the implementation of coherent memory and the factors that affect its performance. We measure the cost of basic operations implementing coherent memory. We also measure the performance of a set of application programs running on PLATINUM. Finally, we comment on the interaction between architecture and the coherent memory system. Platinum currently runs on the BBN Butterfly Plys (TM) Multiprocessor. (KR).

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In this paper we describe several checkpointing algorithms for backward error recovery in virtual shared memory systems. Counterparts to some of these algorithms can be found in message-passing systems, but a shared memory system allows a significant optimization. The read-write semantics of the shared memory can be used to distinguish network messages that do not create dependencies from those that do, whereas all messages passed in a message-passing system are assumed to create dependencies. We measure the performance of the checkpointing algorithms using a trace-driven simulation of several shared memory parallel applications.

Available in PDF, EPUB and Kindle. Book excerpt: Scalable Coherent Interface (SCI) is an innovative interconnect standard (ANSI/IEEE Std 1596-1992) addressing the high-performance computing and networking domain. This book describes in depth one specific application of SCI: its use as a high-speed interconnection network (often called a system area network, SAN) for compute clusters built from commodity workstation nodes. The editors and authors, coming from both academia and industry, have been instrumental in the SCI standardization process, the development and deployment of SCI adapter cards, switches, fully integrated clusters, and software systems, and are closely involved in various research projects on this important interconnect. This thoroughly cross-reviewed state-of-the-art survey covers the complete hardware/software spectrum of SCI clusters, from the major concepts of SCI, through SCI hardware, networking, and low-level software issues, various programming models and environments, up to tools and application experiences.
