High Performance Issues on Parallel Architectures
… to reduce communication latency in mesh-type architectures, these architectures have been augmented by various types of global and reconfigurable bus structures. The static bus structures provide excellent performance in many areas of computation especially structured numerical computations, …

Adding support for heterogeneous parallel architectures to Julia
Traditionally, using a GPGPU to accelerate arbitrary calculations has always been difficult. The common GPGPU platforms introduce new languages exclusively for programming the devices, runtime libraries and new tools that have to be integrated into the build process. That means that using them from …

Transforming and Optimizing Irregular Applications for Parallel Architectures
Parallel architectures, including multi-core processors, many-core processors, and multi-node systems, have become commonplace, as it is no longer feasible to improve single-core performance through increasing its operating clock frequency. Furthermore, to keep up with the exponentially growing …

Performance Analysis of Program Executions on Modern Parallel Architectures
Parallel architectures have become common in supercomputers, data centers, and mobile chips. Usually, parallel architectures have complex features: many hardware threads, deep memory hierarchies, and non-uniform memory access (NUMA). Program designs without careful consideration of these features …

Mapping unstructured mesh codes onto local memory parallel architectures
Initial work on mapping CFD codes onto parallel systems focused upon software which employed structured meshes. Increasingly, many large scale CFD codes are being based upon unstructured meshes. One of the key problems when implementing such large scale unstructured problems on a distributed memory …

Design and implementation of a floating point unit for rigel, a massively parallel accelerator
… and power intensive. The emergence of massively parallel architectures like Rigel creates new challenges and poses new questions with respect to floating point support. The massively parallel aspect of Rigel places great emphasis on area efficient, low power designs. At the same time, Rigel is a …

A class library approach to concurrent object-oriented programming with applications to VLSI CAD
Despite increasing availability, the use of parallel platforms in the solution of significant computing problems remains largely restricted to a set of well-structured, numeric applications. This is due in part to the difficulty of parallel application development, which is itself largely the …

Functional parallelism: Theoretical foundations and implementation
Thus far, parallelism at the loop level (or data-parallelism) has been almost exclusively the main target of parallelizing compilers. The variety of new parallel architectures and recent progress in interprocedural dependence analysis suggest new directions for the exploitation of parallelism …
