This thesis explores the possibility of utilizing Graphics Processing Units (GPUs) to address the computational demand of algorithms used to mitigate the inherent physical limitations in devices such as microscopes and 3D-scanners. We investigate the outcome and test our methodology for the following case studies: – the narrow field of view found in microscopes. – the limited pixel-resolution available in active 3D sensing technologies such as laser scanners. The algorithms that offer to mitigate these limitations suffer from high computational requirements, rendering them ineffective for time-sensitive applications. In our methodology we exploit parallel programming and software engineering practices to efficiently harness the GPU’s potential to provide the needed computational performance. Our goal is to show that it is feasible to use GPU hardware acceleration to address computational requirements of these algorithms for time-sensitive industrial applications. The results of this work demonstrate the potential for using GPU hardware acceleration in meeting computational requirements of such applications. We achieved twice the performance required to algorithmically extend the narrow field of view in microscopes for micro-pathology, and we reached the performance required to upsample the pixel-resolution of a 3D scanner in real-time, for use in autonomous excavation and collision detection in mining.

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.
