This course is an introduction to NVIDIA's CUDA technology and its usage in porting Quantum ESPRESSO (QE) to GPGPU architectures. CUDA, the Compute Unified Device Architecture, is NVIDIA's parallel computing framework that enables programmers to carry out general-purpose computation on graphics processing units (GPUs). Quantum ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling at the nanoscale. Using CUDA, ICHEC has ported the PWscf code in QE to run on hybrid CPU-GPU systems. During the course, students will be introduced to the fundamentals of GPGPU and CUDA; then the ported features of QE are presented along with means to configure the code and datasets for optimal performance.
