Radiotherapy is one of the main cancer treatments used today. It is a complex process that relies on finding the cancer in the images of the patients with the most accuracy possible in order to minimize the radiation that the surrounding organs receive. Given that a typical radiotherapy treatment process lasts for 6 weeks, ideally, a system that performs this analysis in real time reliably would enable a better treatment process. The Western General Hospital and the Edinburgh Cancer Research Center have a prototype system based on texture features analysis of small lung and rectum cancer patients’ images that is currently being developed and used for their research. It was implemented in MATLAB and we used and compared four different technologies to optimize the software: the MATLAB Parallel Toolbox using a small computer cluster, the GPU computing support given by that toolbox, the Jacket add on for GPU computations for MATLAB and finally C/CUDA native function calls from MATLAB, all these GPU technologies were carried on using a NVIDIA Tesla C2050 card.

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.

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