1. 1. Adaptive Computing based on FPGA Run-time Reconfigurability

   Författare :Ming Liu; Lu Zhonghai; Jantsch Axel; Zipf Peter; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptive computing; FPGA partial reconfiguration; Information technology; Informationsteknik;

   Sammanfattning : In the past two decades, FPGA has been witnessed from its restricted use as glue logic towards real System-on-Chip (SoC) platforms. Profiting from the great development on semiconductor and IC technologies, the programmability of FPGAs enables themselves wide adoption in all kinds of aspects of embedded designs. LÄS MER

   Sammanfattning : This thesis aims at decreasing execution time for large-scale structured adaptive mesh refinement (SAMR) applications executing on general parallel computers. The key contributions are (1) A conceptual dynamically adaptive meta-partitioner able to select and configure an appropriate partitioning technique, based on application and computer state, and (2) A characterization of new and existing domain-based partitioners, enabling a mapping from application and computer state onto appropriate partitioners, and (3) Sketched scalable solutions, expressed in terms of natural regions and expert algorithms, for the problem to efficiently partition large-scale SAMR applications with deep grid hierarchies executing on general parallel computers, and (4) A software partitioning tool Nature+Fable, implementing the greater parts of these sketched scalable solutions and engineered as part of the meta-partitioner.
