Heterogeneous networks are increasingly being used as platforms for resource-intensive
distributed parallel applications. A critical contributor to the performance of such applications …

Metacomputing is the aggregation of distributed and high-performance resources on
coordinated networks. With careful scheduling, resource-intensive applications can be …

This paper defines, describes and illustrates a systems engineering process for
development of software systems implementing high performance computing applications …

Structured adaptive mesh refinement (SAMR) methods for the numerical solution of partial
differential equations yield highly advantageous ratios for cost/accuracy as compared to …

We have been pursuing a research program aimed at enhancing productivity and
performance in parallel computing at the Parallel Programming Laboratory of University of …

The development of a high-performance parallel system or application is an evolutionary
process. It may begin with models or simulations, followed by an initial implementation of the …

Distributed applications executing on clustered environments typically share resources
(computers and network links) with other applications. In such systems, application …

Hierarchically organized ensembles of shared memory multiprocessors possess a richer
and more complex model of locality than previous generation multicomputers with single …

In this chapter, we present a summary of the runtime support, compiler and tools
development efforts in the CHAOS group at the University of Maryland. The principal focus of …

We present a small set of programming abstractions to simplify efficient implementations for
block-structured scientific calculations on SMP clusters. We have implemented these …
