DOI: 10.1109/IPDPS.2010.5470442 Structuring the execution of OpenMP applications for multicore architectures
, 2010
"... Abstract—The now commonplace multi-core chips have introduced, by design, a deep hierarchy of memory and cache banks within parallel computers as a tradeoff between the user friendliness of shared memory on the one side, and memory access scalability and efficiency on the other side. However, to get ..."

challenge is then to perform this hardware-dependent mapping in a portable, abstract way. To meet this need, we propose a new, hierarchical approach to the execution of OpenMP threads onto multicore machines. Our ForestGOMP runtime system dynamically generates structured trees out of OpenMP programs
OpenMP in Multicore Architectures
"... OpenMP is an API (application program interface) used to explicitly direct multi-threaded, shared memory parallelism. With the advent of Multi-core processors, there has been renewed interest in parallelizing programs. Multi-core offers support to execute threads in parallel but at the same time the ..."

Towards Autotuning of OpenMP Applications on Multicore Architectures
"... Abstract. In this paper we describe an autotuning tool for optimiza-tion of OpenMP applications on highly multicore and multithreaded ar-chitectures. Our work was motivated by in-depth performance analysis of scientific applications and synthetic benchmarks on IBM Power 775 architecture. The tool pr ..."

Towards an Active Network Architecture
- Computer Communication Review
, 1996
"... Active networks allow their users to inject customized programs into the nodes of the network. An extreme case, in which we are most interested, replaces packets with "capsules" -- program fragments that are executed at each network router/switch they traverse. Active architectures permit ..."

Exokernel: An Operating System Architecture for Application-Level Resource Management
, 1995
"... We describe an operating system architecture that securely multiplexes machine resources while permitting an unprecedented degree of application-specific customization of traditional operating system abstractions. By abstracting physical hardware resources, traditional operating systems have signifi ..."

Transactional Memory: Architectural Support for Lock-Free Data Structures
"... A shared data structure is lock-free if its operations do not require mutual exclusion. If one process is interrupted in the middle of an operation, other processes will not be prevented from operating on that object. In highly concurrent systems, lock-free data structures avoid common problems asso ..."

A Security Architecture for Computational Grids
, 1998
"... State-of-the-art and emerging scientific applications require fast access to large quantities of data and commensurately fast computational resources. Both resources and data are often distributed in a wide-area network with components administered locally and independently. Computations may involve ..."
