Course detail

Computation Systems Architectures

FIT-AVSAcad. year: 2020/2021

The course covers architecture of modern computational systems composed of universal as well as special-purpose processors and their memory subsystems. Instruction-level parallelism is studied on scalar, superscalar and VLIW processors. Then the processors with thread-level parallelism are discussed. Data parallelism is illustrated on SIMD streaming instructions and on graphical processors. Programming for shared memory systems in OpenMP follows and then the most proliferated multi-core multiprocessors and the advanced NUMA systems are described. Finally, the generic architecture of the graphics processing units and basic programming techniques using OpenMP are also covered. Techniques of  low-power processors are also explained.

Aims

To familiarize yourself with the architecture of modern computational systems based on x86, ARM and RISC-V multicore processors in configurations with uniform (UMA) and non-uniform (NUMA) shared memory, often accompanied with a GPU accelerator. To understand hardware aspects of computational systems that have a significant impact on the application performance and power consumption. To be able to assess computing possibilities of a particular architecture and to predict the performance of applications. To clarify the role of a compiler and its cooperation with processors. To be able to orientate oneself on the computational system market, to evaluate and compare various systems.
