High Performance Computing
Instructor: Salvatore Orlando
The objective is to acquire knowledge on models of parallel architectures, paradigm and environments of parallel programming, and performance evaluation of parallel systems.
The course presents the fundamental algorithmic techniques usually employed to solve in parallel significant application problems.
The course is mainly focused on the use of clusters of workstations as parallel platforms.
The students is expected to have a good background in computer architectures, operating systems, computer networks, programming.
- Introduction: Motivations and use cases.
- Parallel architectures
- Parallel programming paradigms
- Parallelization techniques and issues: Decompositions, Mapping, Load balancing.
- Metrics for performance evaluation.
- Basics of parallel algorithms.
- Recurrent paradigms for parallelization.
- Libraries and languages for parallel programming.
- Laboratory work: use of message passing (MPI) and multithread libraries.
