Agent-based modelling and simulation is still an upcoming approach for microsimulation. But a large number of agents with advanced dynamics and interactions requires sophisticated algorithms and lots of computational effort. We try to implement a rather simple but special agent-based model model on GPU-architectures (graphics processing unit). This contribution presents the GPU implementations and and investigates its practicability. Results show that implementation of agent-based systems on a GPU-architecture can deliver enormous speedups. Depending on the detailed structure of the system highly advanced algorithms deliver another great performance-boost. The combination of both approaches can deliver up to 1.000 times faster execution of the same simulation.

Free GPU computing nodes at hgpu.org

Registered users can now run their OpenCL application at hgpu.org. We provide 1 minute of computer time per each run on two nodes with two AMD and one nVidia graphics processing units, correspondingly. There are no restrictions on the number of starts.

The platforms are

Node 1
  • GPU device 0: AMD/ATI Radeon HD 5870 2GB, 850MHz
  • GPU device 1: AMD/ATI Radeon HD 6970 2GB, 880MHz
  • CPU: AMD Phenom II X6 @ 2.8GHz 1055T
  • RAM: 12GB
  • OS: OpenSUSE 13.1
  • SDK: AMD APP SDK 2.9
Node 2
  • GPU device 0: AMD/ATI Radeon HD 7970 3GB, 1000MHz
  • GPU device 1: nVidia GeForce GTX 560 Ti 2GB, 822MHz
  • CPU: Intel Core i7-2600 @ 3.4GHz
  • RAM: 16GB
  • OS: OpenSUSE 12.2
  • SDK: nVidia CUDA Toolkit 6.0.1, AMD APP SDK 2.9

Completed OpenCL project should be uploaded via User dashboard (see instructions and example there), compilation and execution terminal output logs will be provided to the user.

The information send to hgpu.org will be treated according to our Privacy Policy
