Evaluating scheduling policies for fine-grain communication protocols on a cluster of SMPs

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 ...

Wisconsin Wind Tunnel II: a fast, portable parallel architecture simulator

Babak Falsafi, James Richard Larus, David Wood

To analyze new, parallel computers, developers must rapidly simulate designs running realistic workloads. Historically, direct execution and a parallel host have accelerated simulations, although these techniques have typically lacked portability. Through ...

Parallel Dispatch Queue: a queue-based programming abstraction to parallelize fine-grain communication protocols

Babak Falsafi, David Wood

This paper proposes a novel queue-based programming abstraction, Parallel Dispatch Queue (PDQ), that enables efficient parallel execution of fine-grain software communication protocols. Parallel systems often use fine-grain software handlers to integrate a ...

Cacheable Interface Control Registers for High Speed Data Transfer

Babak Falsafi, David Wood

A device interface for communicating between a processor system and a separate device employs cacheable control registers, both to indicate the receipt of a message and to receive messages to be transmitted. The data structure of the cacheable control regi ...

Sirocco: cost-effective fine-grain distributed shared memory

Babak Falsafi, James Richard Larus, David Wood

Software fine-grain distributed shared memory (FGDSM) provides a simplified shared-memory programming interface with minimal or no hardware support. Originally software FGDSMs targeted uniprocessor-node parallel machines. This paper presents Sirocco, a fam ...

Retrospective: Tempest and Typhoon: User-level Shared Memory

James Richard Larus, David Wood

Tempest and Typhoon have emerged as among the most influential contributions of the Wisconsin Wind Tunnel project, a collaborative effort with Prof. Mark D. Hill, several staff members, and a large group of graduate students. This retrospective focuses on ...

ACM1998

This article 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, or if it is also ...

Wisconsin Wind Tunnel II: A Fast and Portable Parallel Architecture Simulator

Babak Falsafi, James Richard Larus, David Wood

The design of future parallel computers requires rapid simulation of target designs running realistic workloads. These simulations have been accelerated using two techniques: direct execution and the use of a parallel host. Historically, these techniques h ...

1997

This paper proposes and evaluates a new approach to directory-based cache coherence protocols called Reactive NUMA (R-NUMA). An R-NUMA system combines a conventional CC-NUMA coherence protocol with a more-recent Simple-COMA (S-COMA) protocol. What makes R- ...
