Parallel Computer Research in the Wisconsin Wind Tunnel Project
The paper summarizes the Wisconsin Wind Tunnel Project’s research into parallel computer design and methods. Our principal design contributions—Cooperative Shared Memory and the Tempest Parallel Programming Substrate—seek to balance the programming benefits of a shared address space with facilities for low-level performance optimizations. The project has refined and compared a variety of ideas ...
متن کاملKernel Support for the Wisconsin Wind Tunnel
This paper describes a kernel interface that provides an untrusted user-level process (an executive) with protected access to memory management functions, including the ability to create, manipulate, and execute within subservient contexts (address spaces). Page motion callbacks not only give the executive limited control over physical memory management, but also shift certain responsibilities ...
متن کاملFast and Portable Parallel Architecture Simulators: Wisconsin Wind Tunnel II
Analysis of future parallel computers requires rapid simulation of target designs running realistic workloads. These simulations have been accelerated by two techniques: direct execution and the use of a parallel host. Historically, these techniques have been considered to lack portability. We identify four key operations necessary to make these simulations portable. This allows us to run the W...
متن کاملWisconsin Wind Tunnel II: a fast, portable parallel architecture simulator
direct execution and parallel simulation. In direct execution, a program from the target system runs on an existing host system.1 For example, a target’s floating-point multiply executes as a floating-point multiply instruction on the host. The host calculates the target’s execution time and simulates only those operations unavailable on the host. Direct execution can run orders of magnitude fa...
متن کاملSimulation of the SCI Transport Layer on the Wisconsin Wind Tunnel
Parallel simulation of parallel machines is fast becoming a critical technique for the evaluation of new parallel architectures and architectural extensions. Fast and accurate simulation of the interconnection network in parallel simulators is extremely difficult, but also extremely important. In this report, we describe an extension to the Wisconsin Wind Tunnel that simulates the transport lay...
