Parallel algorithms for modern high performance computing systems are required for fast modelling of high dimensional convection-diffusion processes in air. Such algorithms, designed for alternate-triangular finite difference splitting schemes applied to convection-diffusion equation, have been considered. An algorithm for single GPU systems and an algorithm for clusters with graphical processors has been described, algorithms’ performance theoretical estimations has been given and results of their testing on SKIT-4 cluster of Institute of Cybernetics has been presented. Obtained testing results about developed algorithms’ performance with sufficient accuracy agree with theoretical estimations.

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: nVidia GeForce GTX 560 Ti 2GB, 822MHz
  • 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: nVidia CUDA Toolkit 6.5.14, AMD APP SDK 3.0
Node 2
  • GPU device 0: AMD/ATI Radeon HD 7970 3GB, 1000MHz
  • GPU device 1: AMD/ATI Radeon HD 5870 2GB, 850MHz
  • CPU: Intel Core i7-2600 @ 3.4GHz
  • RAM: 16GB
  • OS: OpenSUSE 12.3
  • SDK: AMD APP SDK 3.0

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.
