The high-level parallel language ZPL improves productivity and performance

by Bradford L. Chamberlain, Sung-eun Choi, Steven J. Deitz, Lawrence Snyder - In Proceedings of the IEEE International Workshop on Productivity and Performance in High-End Computing , 2004
"... In this paper, we qualitatively address how high-level parallel languages improve productivity and performance. Using ZPL as a case study, we discuss advantages that stem from a language having both a global (rather than a perprocessor) view of the computation and an underlying performance model tha ..."

Performance of a High-Level Parallel Language on a High-Speed Network

by Henri Bal, Raoul Bhoedjang, Rutger Hofman, Ceriel Jacobs, Koen Langendoen, Tim Rühl, Kees Verstoep - Journal of Parallel and Distributed Computing , 1997
"... Clusters of workstations are often claimed to be a good platform for parallel processing, especially if a fast network is used to interconnect the workstations. Indeed, high performance can be obtained for low-level message passing primitives on modern networks like ATM and Myrinet. Most applicati ..."

). In this paper we investigate the issues involved in implementing a high-level programming environment on a fast network. We have implemented a portable runtime system for an object-based language (Orca) on a collection of processors connected by a Myrinet network. Many performance optimizations were required

Evaluating a High-Level Parallel Language (GpH) for Computational Grids

by Abdallah D. Al Zain, Phil W. Trinder, Greg J. Michaelson, Hans-wolfgang Loidl - IEEE Transactions on Parallel and Distributed Systems
"... Abstract—Computational GRIDs potentially offer low-cost, readily available, and large-scale high-performance platforms. For the parallel execution of programs, however, computational GRIDs pose serious challenges: they are heterogeneous and have hierarchical and often shared interconnects, with high ..."

The Paradyn Parallel Performance Measurement Tools

by Barton P. Miller, Mark D. Callaghan, Jonathan M. Cargille, Jeffrey K. Hollingsworth, R. Bruce Irvin , Karen L. Karavanic, Krishna Kunchithapadam, Tia Newhall - IEEE COMPUTER , 1995
"... Paradyn is a performance measurement tool for parallel and distributed programs. Paradyn uses several novel technologies so that it scales to long running programs (hours or days) and large (thousand node) systems, and automates much of the search for performance bottlenecks. It can provide precise ..."
Abstract - Cited by 447 (39 self) - Add to MetaCart
. It also provides an open interface for performance visualization, and a simple programming library to allow these visualizations to interface to Paradyn. Paradyn can gather and present performance data in terms of high-level parallel languages (such as data parallel Fortran) and can measure programs

Visualizing High-Level Communication And Synchronization

by Rutger Hofman, Koen Langendoen, Henri Bal - IEEE Int. Conference on Algorithms and Architectures for Parallel Processing (ICA3PP), Singapore , 1996
