Abstract / Description of output

Reconfigurable computing is a promising approach with both flexibility and efficiency for high performance computing. However, the overhead of run-time reconfiguration affects the performance severely. In the paper, we develop a simple and effective method to hide the latency of configuration by configuration prefetching at runtime. A simulation platform based on Simics is developed for evaluation. The experimental results show that the predictive accuracy is rather high, the hit rate of reconfigurable processing unit is increased by 24.6%~53.7% when reconfigurable resource is not adequate.
