Learning objectives:
  To familiarize students with architecture of the newest processors exploiting the instruction-level parallelism and its impact on a compiler design. To make them understand features of parallel systems which make use of functional parallelism at a process- or thread-level and also data parallelism.
  The course covers architecture of processors and parallel systems. Instruction- and thread-level parallelism (ILP, TLP) is studied on scalar, superscalar, VLIW and multithreaded processors. Next, in the context of process-level parallelismus, the most frequently used bus-based symmetric multiprocessors are dealt with. Then the treatment of interconnection networks follows, as a base of systems with a distributed shared memory (NUMA) and of multicomputers with local memories, especially popular clusters of workstations and massively parallel systems. The last part is devoted to parallel vector processors and SIMD-style processing (data parallelism).
Knowledge and skills required for the course:
  Von-Neumann computer architecture, computer memory hierarchy, cache memories and their organization, programming in assembly and in C/C++, compiler's tasks and functions
Learning outcomes and competencies:
  Overview of processor microarchitecture and its future trends, principles of parallel system design and interconnection networks, ability to estimate performance of parallel applications.
