Software vs. Hardware Shared Memory Implementation: A Case Study

Willy Zwaenepoel, Sandhya Dwarkadas

We compare the performance of software-supported shared memory on a general-purpose network to hardware-supported shared memory on a dedicated interconnect. Up to eight processors, our results are based on the execution of a set of application programs on ...

Fine-grain access control for distributed shared memory

Babak Falsafi, James Richard Larus, David Wood

The 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. The paper focus ...

Where is Time Spent in Message-Passing and Shared-Memory Programs?

James Richard Larus

Message passing and shared memory are two techniques parallel programs use for coordination and communication. This paper studies the strengths and weaknesses of these two mechanisms by comparing equivalent, well-written message-passing and shared-memory p ...

Network Multicomputing Using Recoverable Distributed Shared Memory

Willy Zwaenepoel, Sandhya Dwarkadas

A network multicomputer is a multiprocessor in which the processors are connected by general-purpose networking technology, in contrast to current distributed memory multiprocessors where a dedicated special-purpose interconnect is used. The advent of high ...

Cooperative Shared Memory: Software and Hardware for Scalable Multiprocessors

James Richard Larus, David Wood

We believe the paucity of massively parallel, shared-memory machines follows from the lack of a shared-memory programming performance model that can inform programmers of the cost of operations (so they can avoid expensive ones) and can tell hardware desig ...

Implementation and Performance of Munin

Willy Zwaenepoel

Munin is a distributed shared memory (DSM) system that allows shared memory parallel programs to be executed efficiently on distributed memory multiprocessors. Munin is unique among existing DSM systems in its use of multiple consistency protocols and in ...

Cache Considerations for Programmers of Multiprocessors

James Richard Larus

Although caches in most computers are invisible to programmers, they significantly affect program performance. This is particularly true for cache-coherent, shared-memory multiprocessors. This article presents recent research into the performance of parall ...

Munin: Distributed Shared Memory Based on Type-Specific Memory Coherence

Willy Zwaenepoel

We are developing Munin y , a system that allows pro grams written for shared memory multiprocessors to be executed efficiently on distributed memory machines. Thus, Munin overcomes the architectural limitations of shared memory machines, while maintain ...

Lisp Extensions for Multiprocessing

James Richard Larus

Extensions to Common Lisp for concurrent computation on multiprocessors are discussed. Functions for process creation, communication, and synchronization are described. Process objects create multiple threads of control. Processes are lightweight so that p ...
