Course plan

Lectures

Ca. 32h, given in block format in 2 intensive weeks in February and early March 2011.

Recommended for

Graduate (CUGS, CIS, ISY, ...) students interested in the areas of parallel computer architecture, parallel programming, software engineering, optimization, compiler construction, or algorithms and complexity.

The course was last given

in VT2009.

Goals

The course emphasizes fundamental aspects of shared-memory parallel programming such as shared memory parallel architecture concepts, programming models, performance models, parallel algorithmic paradigms, parallelization techniques and strategies, scheduling algorithms, optimization, composition of parallel programs, and concepts of modern parallel programming languages and systems. Practical exercises help to apply the theoretical concepts of the course to solve concrete problems in a real-world multicore system.

Prerequisites

Data structures and algorithms are absolutely required; some knowledge in complexity theory and compiler construction is useful. Some basic knowledge of computer architecture is assumed. A basic course in concurrent programming (e.g. TDDB68) and parallel programming (e.g. TDDC78 or TANA77) are recommended.
Programming in C and some familiarity with Linux (or similar OS) is necessary for the practical exercises.

Examiner

Christoph Kessler, Linköpings universitet

Examination

TEN1: Written exam 4.5hp.
UPG1: Programming exercise (lab report) 1.5hp.
UPG2: Paper presentation, opposition, and written summary (1-2 pages) of the presented paper, 1.5hp.

Credit

7.5hp if all examination moments are fulfilled.
Partial credits can be given, too.

Organized by

CUGS

Comments

There is a partial overlap in contents with FDA125 Advanced Parallel Programming, which corresponds to 1p = 1.5hp in the written exam.

In contrast to FDA125, we focus in this course on shared memory systems and add more material on software engineering techniques for parallel systems, such as design patterns for synchronization and optimized composition of parallel components. We also give more emphasis to parallelization techniques that are especially useful for multicore systems, such as speculative parallelization, transactional programming and lock-free synchronization. Scheduling for shared memory systems will be considered in more detail, in particular scheduling algorithms for malleable task graphs.
