DN2264 Parallel Computations for Large-Scale Problems, Part 1 6.0 credits

Basic ideas including hardware architectures, memory hierarchies, communications, parallelization strategies, measures of efficiency;

Simple numerical algorithms including matrix operations, Gaussian elimination;

Algorithms on graphs including graph partitioning problems;

Parallel sorting;

More advanced parallel problems including the n-body problem;

Advanced numerical methods including multi-grid and FFT methods;

Standard libraries.

The overall goal of the course is to provide a basic understanding of how to develop algorithms and how to implement them in distributed memory computers using the message-passing paradigm.

This understanding means that after the course you are able to

• explain parallelization strategies;
• select and/or develop an algorithm for solving a given problem which has the potential for an efficient parallelization;
• select and/or develop data structures for implementing parallel computations;
• theoretically analyze a given parallel algorithm with respect to efficiency;
• implement a given algorithm on a distributed-memory computer using the message passing library MPI;
• understand the message flow and avoid unwanted situations (e.g. deadlock, synchronization delays);
• modify and adapt a set of basic routines to special situations;
• experimentally evaluate the performance of a parallel program;
• explain differences between the theoretically expected performance and the practically observed performance.

Single course students: 90 university credits including 45 university credits in Mathematics or Information Technology. English B, or equivalent.

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

If the course is discontinued, students may request to be examined during the following two academic years.

In this course all the regulations of the code of honor at the School of Computer science and Communication apply, see: http://www.kth.se/csc/student/hederskodex/1.17237?l=en_UK.

Homework and a mid-term quiz (HEM1; 3 university credits)
Lab report (LAB1; 3 university credits)

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

Please observe that the first lesson is compulsary to attend.
