Fine-grain Access Control for Distributed Shared Memory

by Ioannis Schoinas, Steven K. Reinhardt, James R. Larus, David A. Wood - In Proceedings of the Sixth International Conference on Architectural Support for Programming Languages and Operating Systems (ASPLOS VI , 1994
"... This paper discusses implementations of fine-grain memory access control, which selectively restricts reads and writes to cache-block-sized memory regions. Fine-grain access control forms the basis of efficient cache-coherent shared memory. This paper focuses on low-cost implementations that require ..."

is enforced and where access conflicts are handled. We incorporated three techniques that require no additional hardware into Blizzard, a system that supports distributed shared memory on the CM-5. The first adds a software lookup before each shared-memory reference by modifying the program's executable

A File System for Continuous Media

by David P. Anderson, Yoshitomo Osawa, Ramesh Govindan , 1992
"... INTRODUCTION Current disk drives have raw data rates of 5 to 10 million bits per second (Mbps) or more. Such rates suffice for many forms of digital audio and motion video (continuous media, or CM) data: audio data rates are from 8 Kbps to 1.4 Mbps, while compressed video ranges from one to several ..."

Supporting Dynamic Data Structures on Distributed-Memory Machines

by Anne Rogers, Martin C. Carlisle, John H. Reppy, Laurie J. Hendren , 1995
"... this article, we describe an execution model for supporting programs that use pointer-based dynamic data structures. This model uses a simple mechanism for migrating a thread of control based on the layout of heap-allocated data and introduces parallelism using a technique based on futures and lazy ..."

task creation. We intend to exploit this execution model using compiler analyses and automatic parallelization techniques. We have implemented a prototype system, which we call Olden, that runs on the Intel iPSC/860 and the Thinking Machines CM-5. We discuss our implementation and report on experiments

Metascheduling for continuous media

by David P. Anderson - ACM Transactions on Computer Systems , 1993
"... Next-generation distributed systems will support corLtLzLzLous medLa (digztal audio and video) in the same framework as other data. Many applications that use continuous media need guaran-teed end-to-end performance (bounds on throughput and delay). To reliably support these requirements, system com ..."

components such as CPU schedulers, networks, and file systems must offer performance guarantees. A rnetasclzedtder coordinates these components, negotiating end-to-end guarantees on behalf of clients. The CM-resource model, described in this paper, provides a basis for such a metascheduler. It defines a
