What is CUDA?
CUDA is NVIDIA’s parallel computing architecture that enables dramatic increases in computing performance by harnessing the power of the GPU (graphics processing unit), which performs better in computation in applications traditionally handled by the CPU.
CUDA has several advantages over traditional general purpose computation on GPUs:
Scattered reads – code can read from arbitrary addresses in memory.
Shared memory – CUDA exposes a fast shared memory region (16KB in size) that can be shared amongst threads. This can be used as a user-managed cache, enabling higher bandwidth than is possible using texture lookups.
Faster downloads and readbacks to and from the GPU.
Full support for integer and bitwise operations, including integer texture lookups.
DVDFab products are among the earliest applications adopt NVIDIA CUDA technology which can largely improve the performance of app’s computation and video encoding/decoding, in particular for HD video’s processing. For happier user experience of customers, DVDFab keeps improving and has been updated with the newest NVIDIA CUDA. Now, with a computer running on CUDA-enabled GPU, you can use DVDFab products to copy/rip your DVD/Blu-ray movies or convert videos in a speed much faster than ever before, although DVDFab has always been saving your time with multi-core CPUs and batch conversion supported. And your computer will run much smoother since more CPU resources are spared. Thanks for CUDA!
