Algorithmic Issues on Heterogeneous Computing Platforms

Issues in using heterogeneous HPC systems for embedded real time signal processing applications

Embedded signal processing systems have traditionally been built using custom VLSI to meet real-time requirements. This leads to limited programmability and restricted exibility. With recent technological advances in high performance computing, scalable systems based on heterogeneous \oo the shelf" modules are attractive as computing platforms in real-time embedded environments, leading to an e...

Enabling Legacy Applications on Heterogeneous Platforms

In this paper we make the case for a runtime technique to seamlessly execute legacy applications on heterogeneous platforms consisting of CPUs and accelerators. We consider discrete as well as integrated heterogeneous platforms. In the former, CPU and accelerators have different memory systems; in the latter, accelerators share physical memory with the CPU. Our proposed runtime does not require...

Heterogeneous Grid Computing: Issues and Early Benchmarks

A heterogeneous implementation of the current LCG2/EGEE grid computing software is supported in the Grid-Ireland infrastructure. The porting and testing of the current software version of LCG2 is presented for different flavours of Linux, namely Red Hat 7.3, Red Hat 9 and Fedora Core 2. The GridBench micro-benchmarks developed in CrossGrid are used to compare the different platforms.

Tiling for Heterogeneous Computing Platforms Ecole Normale Supérieure De Lyon Tiling for Heterogeneous Computing Platforms Tiling for Heterogeneous Computing Platforms

In the framework of fully permutable loops tiling has been extensively studied as a source to source program transformation However little work has been devoted to the mapping and scheduling of the tiles on physical processors Moreover targeting hetero geneous computing platforms has to the best of our knowledge never been considered In this paper we extend tiling techniques to the context of l...
