Summary  This course introduces theoretical design principles and analysis techniques that enable the creation and evaluation of efficient, scalable and portable algorithms for parallel computers. Concrete examples will span a range of application areas and architectural models seeking wherever possible to exploit commonality through appropriate abstraction. 
Course description 
Introduction: Conceptual frameworks for parallelism, message passing, shared address space, PRAM. Cost models for parallel algorithms. Cost efficiency and scalability. Intermodel emulation. Simple examples.
Problem solving strategies: Embarrassing parallelism, divide & conquer, pipelining, stepbystep parallelisation. Amdahl's Law. Gustafson's law.
Useful primitives: Collective communications, reduction, prefix.
Algorithms in selected problem areas, for example: Sorting (bitonic mergesort, hyperquicksort). Matrix oriented algorithms (multiplication, solving linear systems). Graph algorithms (spanning trees, single source & alltoall shortest paths).

Learning Outcomes
On completion of this course, the student will be able to:
 Define the structure of, and cost models associated with, the PRAM, mesh and hypercube models of parallel computation.
 Define the metrics of cost, speedup and efficiency and use these as conceptual tools with which to analyse and discriminate between alternative candidate parallel algorithms for given problems; demonstrate, by the use of appropriately chosen examples, the importance of scalability in parallel algorithm design.
 Explain and, with appropriate use of diagrams, sketch the structure and operation of well known parallel algorithms in a range of application areas..
 Apply a range of parallel algorithm design techniques (including divideandconquer and pipelining) to previously unseen problems, in order to create new parallel algorithms, which they will be able to describe using an informal mix of pseudocode, textual explanation and diagrams.
 5. Understand and explain the limitations of applying these models to predict actual parallel performance.
