We demonstrate that data reordering can substantially improve the performance of fine-grained irregular sharedmemory benchmarks, on both hardware and software shared-memory systems. In particular, we evaluate two distinct data reordering techniques that se ...
We present two software DSM protocols that dynamically adapt between a single writer (SW) and a multiple writer (MW) protocol based on the application's sharing patterns. The first protocol (WFS) adapts based on write-write false sharing; the second (WFS+W ...
In this paper, we describe Teapot, a domain-specific language for writing cache coherence protocols. Cache coherence is of concern when parallel and distributed systems make local replicas of shared data to improve scalability and performance. In both dist ...
Unlike compiler-generated message-passing code, the coherence mechanisms in shared-memory systems work equally well for regular and irregular programs. In many programs, however compile-time information about data accesses would permit data to be transferr ...
We describe an integrated compile-time and run-time system for efficient shared memory parallel computing on distributed memory machines. The combined system presents the user with a shared memory programming model, with its well-known benefits in terms of ...
We investigate the use of a software distributed shared memory (DSM) layer to support irregular computations on distributed memory machines. Software DSM supports irregular computation through demand fetching of data in response to memory access faults. Wi ...
We describe an implementation of a sizable subset of OpenMP on networks of workstations (NOWs). By extending the availability of OpenMP to NOWs, we overcome one of its primary drawbacks compared to MPI, namely lack of portability to environments other than ...
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, ...
In this paper we evaluate the use of software distributed shared memory (DSM) on a message passing machine as the target for a parallelizing compiler. We compare this approach to compiler-generated message passing, hand-coded software DSM and hand-coded me ...
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 ...
