Course details

Parallel Computations on GPU

PCG Acad. year 2019/2020 Winter semester 5 credits

The course covers the architecture and programming of graphics processing units by the NVidia and partially AMD. First, the architecture of GPUs is studied in detail. Then, the model of the program execution using hierarchical thread organisation and the SIMT model is discussed. Next, the memory hierarchy and synchronization techniques are described. After that, the course explains novel techniques of dynamic parallelism and data-flow processing concluded by practical usage of multi-GPU systems in environments with shared (NVLink) and distributed (MPI) memory. The second part of the course is devoted to high level programming techniques and libraries based on the OpenACC technology.

Subject specific learning outcomes and competences

Knowledge of the parallel programming on GPUs in the area of general purpose computing, orientation in the area of accelerated systems, libraries and tools.  

Generic learning outcomes and competences

Understanding of hardware limitations having impact on the efficiency of software solutions. 

Learning objectives

To familiarize yourself with the architecture and programming of graphics processing unit in the area of general purpose computuing using the NVidia libraries and OpenACC standard. To learn how to design and implement accelerated programs exploiting the potential of GPUs. To gain knowledge about the available libraries for programming on GPUs.

Why is the course taught

The future of computation systems ranging from ordinary PC up to top supercomputers is seen in heterogeneous systems where the sequential parts and the logic is processed by CPUs while the computational parts are offload to accelerators, in this case GPUs. This course will teach you the architecture and software libraries for programming graphics processing units in the area of general purpose computations. 

Prerequisite kwnowledge and skills

Knowledge gained in courses AVS and partially in PRL and PPP.
