  • (GPU) Computing
    Graphics Processing Unit (GPU) computing This section describes the graphics processing unit (GPU) computing feature of OptiSystem. Note: The GPU computing feature is only configurable with OptiSystem Version 11 (or higher) What is GPU computing? GPU computing or GPGPU takes advantage of a computer’s grahics processing card to augment the speed of general purpose scientific and engineering computing tasks. Compute Unified Device Architecture (CUDA) implementation for OptiSystem NVIDIA revolutionized the GPGPU and accelerated computing when it introduced a new parallel computing architecture: Compute Unified Device Architecture (CUDA). CUDA is both a hardware and software architecture for issuing and managing computations within the GPU, thus allowing it to operate as a generic data-parallel computing device. CUDA allows the programmer to take advantage of the parallel computing power of an NVIDIA graphics card to perform general purpose computations. OptiSystem CUDA implementation The OptiSystem model for GPU computing involves using a central processing unit (CPU) and GPU together in a heterogeneous co-processing computing model. The sequential part of the application runs on the CPU and the computationally-intensive part is accelerated by the GPU. In the OptiSystem GPU programming model, the application has been modified to map the compute-intensive kernels to the GPU. The remainder of the application remains within the CPU. CUDA parallel computing architecture The NVIDIA CUDA parallel computing architecture is enabled on GeForce®, Quadro®, and Tesla™ products. Whereas GeForce and Quadro are designed for consumer graphics and professional visualization respectively, the Tesla product family is designed ground-up for parallel computing and offers exclusive computing 3 GRAPHICS PROCESSING UNIT (GPU) COMPUTING features, and is the recommended choice for the OptiSystem GPU.
