| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Computer generated hologram (CGH) is a technology for realizing 3D displays. Large-scale CGH has a merit that it resolves problems existing 3D displays have. However, generating CGH requires memory space and calculation time, and these are in proportion to pixel number. Thus, large-scale CGH can not be generated in real time and it is the reason why CGH is not suit to practical use yet. Computation of CGH is comprised of data-independent operations and GPU has many processing cores. We had accelerated the CGH generation by using single GPU and object decomposition method. However that still takes long time. Thus, we accelerate the CGH generation by using multi-GPU cluster. The results show that we have achieved 134.7 times speed-up compared to sequential program execution by CPU. |
