Original Abstract

In this work, we show that consumer-level $100 GPU can be used to significantly speed-up optimization of 0/1 Knapsack problem. We identify strong and weak points of GPU architecture and propose our parallel genetic algorithm model implemented in CUDA running entirely on the GPU. We show that GPU must be utilized for sufficiently long time in order to obtain reasonable program speedup. Then we compare results quality and speed of our model with single-threaded CPU code implemented using Galib. Peak speedup of GPU GA execution performance is 1340x resp. 134x for 4-bit resp. 40-bit problem instances while maintaining reasonable results quality.
