Acceleration of Computing the Kleene Star in Max-Plus Algebra Using CUDA GPUs
Hiroyuki Goto · IEICE Transactions on Information and Systems · 2011
This research aims to accelerate the computation module in max-plus algebra using CUDA technology on graphics processing units (GPUs) designed for high-performance computing. Our target is the Kleene star of a weighted adjacency matrix for directed acyclic graphs (DAGs). Using a inexpensive GPU card for our experiments, we obtained more than a 16-fold speedup compared with an Athlon 64 X2.
