Master Program (Laurea Magistrale) in Computer Science and Networking
Academic Year 2012-13
High Performance Computing
Course objectives
This course deals with two interrelated issues in high-performance computing:
1. fundamental concepts and techniques in parallel computation structuring and design, including parallelization methodologies and paradigms, parallel programming models, their implementation, and related cost models;
2. architectures of high-performance computing systems, including shared memory multiprocessors, distributed memory multicomputers, clusters, and others.
Both issues are studied in terms of structural model, static and dynamic support to computation and programming models, performance evaluation, capability for building complex and heterogeneous applications and/or enabling platforms, also through examples of application cases. Technological features and trends are studied, in particular multi-/many-core technology and high-performance networks.
An initial part is dedicated to review basic concepts and techniques in structured computer architecture, in order to render the different backgrounds of students as uniform as possible.
