What is GPU Computing?

GPU accelerated computing offers unprecedented application performance by off-loading compute-intensive portions to the GPU. Each GPU consists of thousands of smaller and more efficient cores for handling multiple tasks. Applications are computed much faster in a parallel computing environment with GPU accelerating. By June 2016, our HPC cluster – Jade supports GPU accelerated computing with 2 NVIDIA K80 […]

What is CUDA-Aware MPI?

Message Passing Interface (MPI) is a standard API for communicating data between distributed processes. It is commonly used in HPC to build applications that can scale to multi-nodes. CUDA-Aware MPI is communicating data between difference GPU processors without staging through system memory. For more detailed information, please refer to the following webpages: An Introduction to CUDA-Aware […]
