CS 290N: Parallel Computer Architectures


Announcements

Final Project Reports due Friday 12/15


Time: WF 1-2:50
Room: Phelps 1401
Instructor: Prof. Fred Chong; office hours by appointment; Eng I 5163

As the computing industry struggles to meet performance expectations set by Moore's Law, many-core architectures have become the wave of the future. This course will examine the foundations of parallel architecture and the basic mechanisms to support efficient parallel computation. Topics may include: multiprocessor synchronization, speculative locks, transactional memory, interconnect design, application partitioning, race detection, and reliability issues.


Grading

  • Problem Sets 25%
  • Discussion Topics 20%
  • Project Proposals and Drafts 15%
  • Project Final Report 40%

    Discussion Information

  • Assign a paper for the class to read, one week before your discussion day.
  • Present the paper and supplemental material on your assigned day. Lead discussion, with my help, on the subject.

    Problem Set Information

    For each assigned paper, write up the following and hand in hardcopy to me at the beginning of class:
  • A summary of the main points of the paper.
  • A critique of any shortcomings of the paper.
  • Any ideas on how one would extend the ideas in the paper or address its shortcomings.

    Project Information

    Here is an example project paper. The project has two goals:
  • A critique of three related research papers. This is not a book report. Do not just summarize what is in the papers. Point out shortcomings and possible areas for extension.
  • Extension of the area. Address shortcomings or extend the work in the papers. Come up with some ideas and test them with a short project. This can be in the form of some simple analysis, study of application attributes, small machine simulations, or implementation on parallel machines. Remember to pick something that will fit in a quarter.

    Ideally, both goals would be well-addressed in a project. Since we only have a quarter, however, you may emphasize one or the other.
