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 ...

StormWatch: A Tool for Visualizing Memory System Protocols

James Richard Larus

Recent research has offered programmers increased options for programming parallel computers by exposing system policies (e.g., memory coherence protocols) or by providing several programming paradigms (e.g. message passing and shared memory) on the same p ...

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 ...

From Causal Consistency to Sequential Consistency in Shared Memory Systems

André Schiper

Sequential consistency and causal consistency constitute two of the main consistency criteria used to define the semantics of accesses in the shared memory model. An execution is sequentially consistent if all processes can agree on a same legal sequential ...

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 ...

Tempest and Typhoon: User-Level Shared Memory

James Richard Larus, David Wood

Future parallel computers must efficiently execute not only hand-coded applications but also programs written in high-level, parallel programming languages. Today’s machines limit these programs to a single communication paradigm, either message-passing or ...

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 ...

Cachier: A Tool for Automatically Inserting CICO Annotations

James Richard Larus

Shared memory in a parallel computer provides programmers with the valuable abstraction of a shared address space--through which any part of a computation can access any datum. Although uniform access simplifies programming, it also hides communication, wh ...

Application-specific protocols for user-level shared memory

Babak Falsafi, James Richard Larus, David Wood

Recent distributed shared memory (DSM) systems and proposed shared-memory machines have implemented some or all of their cache coherence protocols in software. One way to exploit the flexibility of this software is to tailor a coherence protocol to match a ...

The Wisconsin Wind Tunnel: Virtual Prototyping of Parallel Computers

James Richard Larus, David Wood

We have developed a new technique for evaluating cache coherent, shared-memory computers. The Wisconsin Wind Tunnel (WWT) runs a parallel shared-memory program on a parallel computer (CM-5) and uses execution-driven, distributed, discrete-event simulation ...
