    Generating large-pixel-count holograms for 3D displays is computationally intensive. A graphics processing unit (GPU) cluster significantly accelerates hologram computation, enabling faster creation of complex holographic displays.

    Area of Science:

    • Computer graphics
    • Holography
    • High-performance computing

    Background:

    • Large-pixel-count holograms are crucial for large-size holographic 3D displays.
    • Generating these holograms is computationally intensive, posing a significant challenge.

    Purpose of the Study:

    • To develop a computationally efficient method for generating large-pixel-count holograms.
    • To accelerate hologram computation for large-scale holographic 3D display applications.

    Main Methods:

    • Implemented a distributed hologram computation system on a graphics processing unit (GPU) cluster (32.5 Tflop/s).
    • Utilized speed improvement techniques: shared GPU memory, GPU-level adaptive load balancing, and node-level load distribution.
    • Employed diffraction limits and hologram subdivision to overcome GPU memory constraints for large holograms.
