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 ...

Coherent network interfaces for fine-grain communication

Babak Falsafi, David Wood

Using coherence can improve performance by facilitating burst transfers of whole cache blocks and reducing control overheads. This paper describes an attempt to explore network interfaces that use coherence, i.e., coherent network interfaces (CNIs), to imp ...

Where is Software Headed? A Virtual Roundtable

James Richard Larus, David Wood

To find out where software is headed, experts in academia and industry share their vision of software's future. It is a snapshot in time of where we have been and possibly where we are headed. The subjects discussed are: the desktop; software technology; o ...

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 ...

Mechanisms for Cooperative Shared Memory

Babak Falsafi, James Richard Larus, David Wood

We introduce a new organization for multi-bank caches: the skewed-associative cache. A two-way skewed-associative cache has the same hardware complexity as a two-way set-associative cache, yet simulations show that it typically exhibits the same hit ratio ...

Cost/performance of a parallel computer simulator

Babak Falsafi, David Wood

This paper examines the cost/performance of simulating a hypothetical target parallel computer using a commercial host parallel computer. We address the question of whether parallel simulation is simply faster than sequential simulation, and whether it is ...

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 ...

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 ...

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 ...
