Protocol-based Data-race Detection

James Richard Larus

Distributed Shared-Memory (DSM) computers, which partition physical memory among a collection of workstationlike computing nodes, are now a common way to implement parallel machines. Recently, there has been much interest in DSM machines that use software, ...

Quantifying the Performance Differences Between PVM and TreadMarks

Willy Zwaenepoel, Sandhya Dwarkadas

We compare two systems for parallel programming on networks of workstations: Parallel Virtual Machine (PVM) a message passing system, and TreadMarks, a software distributed shared memory (DSM) system. We present results for eight applications that were imp ...

Scheduling communication on an SMP node parallel machine

Babak Falsafi, David Wood

Distributed-memory parallel computers and networks of workstations (NOWs) both rely on efficient communication over increasingly high-speed networks. Software communication protocols are often the performance bottleneck. Several current and proposed parall ...

Experience with a Language for Writing Coherence Protocols

James Richard Larus

In this paper we describe our experience with Teapot [7], a domain-specific language for writing cache coherence protocols. Cache coherence is of concern when parallel and distributed computing systems make local replicas of shared data to improve scalabil ...

The Tempest Approach to Distributed Shared Memory

James Richard Larus, David Wood

This paper summarizes how distributed shared memory (DSM) can be both efficiently and portably supported by the Tempest interface. Tempest is a collection of mechanisms for communication and synchronization in parallel programs. These mechanisms provide co ...

Compiler-directed Shared-Memory Communication for Iterative Parallel Applications

James Richard Larus

Many scientific applications are iterative and specify repetitive communication patterns. This paper shows how a parallel-language compiler and a predictive cache-coherence protocol in a distributed shared memory system together can implement shared-memory ...

A Comparison of Entry Consistency and Lazy Release Consistency Implementations

Willy Zwaenepoel, Sandhya Dwarkadas, Sarita Vikram Adve

This paper compares several implementations of entry consistency (EC) and lazy release consistency (LRC), two relaxed memory models in use with software distributed shared memory (DSM) systems. We use six applications in our study: SOR, Quicksort, Water, B ...

Evolutive Prototyping of Heterogeneous Distributed Systems Using Hierarchical Algebraic Petri Nets

This paper presents several extensions to a new evolutive prototyping process, called object-oriented mixed prototyping. Our application field is complex distributed systems modelled by the means of CO-OPN, a hierarchical algebraic Petri net language. CO-O ...

Techniques for Reducing Consistency-Related Communication in Distributed Shared Memory System

Willy Zwaenepoel

Distributed shared memory 8DSM) is an abstraction of shared memory on a distributed memory machine. Hardware DSM systems support this abstraction at the architecture level; software DSM systems support the abstraction within the runtime system. One of the ...

Tempest: A Substrate for Portable Parallel Programs

James Richard Larus, David Wood

The paper describes Tempest, a collection of mechanisms for communication and synchronization in parallel programs. With these mechanisms, authors of compilers, libraries, and application programs can exploit-across a wide range of hardware platforms-the b ...
