There will be four major aspects of the course:

  • Part I will start with current trends in high-end computing systems and environments, and continue with a practical short description on parallel programming with MPI, OpenMP, and Pthreads.

 

  • Part II will illustrate the modeling of problems from physics and engineering in terms of partial differential equations (PDEs), and their numerical discretization using finite difference, finite element, and spectral approximation.

 

  • Part III will be on solvers: both iterative for the solution of sparse problems of part II, and direct for dense matrix problems.  Algorithmic and practical implementation aspects will be covered.

 

  • Finally in Part IV, various software tools will be surveyed and used.  This will include PETSc, Sca/LAPACK, MATLAB, and some tools and techniques for scientific debugging and performance analysis.

 

The grade would be based on homework, a midterm project, a final project, and a final project presentation. Topics for the final project would be flexible according to the student's major area of research.

Schedule Class Final Reports

 

 

The project is to describe and demonstrate what you have learned in class.

The idea is to take an application and implement it on a parallel computer.

Describe what the application is and why this is of importance.

You should describe the parallel implementation, look at the performance,

perhaps compare it to another implementation if possible.

You should write this up in a report, 10-15 pages, and in class you will have

20 minutes to make a presentation.

 

 

Here are some ideas for projects:
