Networks and Concurrent Computing

Annoucements

• 9-Jan-2002: At long last, the answers and discussion for the final exam have been posted. You are also quite welcome to stop by my office and pick up your graded exam.
• 15-Dec-2001: Look below for a list of questions and answers that people have sent about the final exam material.
• 29-Nov-2001: To submit the merge sort assignment, you should use the submit command with an assignment name of mergesort (with no spaces or anything else). Let me know if you have trouble submitting.
• 28-Nov-2001: There is a need for tutors on networking material for CS 5 students. If you are interested, please contact me. It could be a good way to review networking material for the exam!
• 8-Nov-2001: I've finally posted instructions for electronic submission -- they can be found below. Also note that I've posted a page on the plus-scan in NESL assignment on the Assignments page. Be sure to check it out and ensure that you're doing everything required.
• 26-Oct-2001: The manual and user's guide for NESL has been posted (see below). Be sure not only that you can read it, but that you can also login to romulus.amherst.edu, preferrably with VNC to get a graphical environment in which to work, and are able to run NESL itself with the runnesl.sh command, which is located in the following directory:

  /mnt/user1/sfkaplan/local-installations/bin

• 9-Oct-2001: Check the Assignments pages, as solutions to Problem Set 1 have been posted. I will be handing back your graded work tomorrow.
• 1-Oct-2001: I will be meeting with Professor Cox, in his office (SMudd 404), to ask him questions about CRC's and polynomials at 4 pm, today. You are welcome to join us!
• 25-Sept-2001: Problem set 1 has been posted on the Assignments page.
• 24-Sept-2001: I was unable to put together the problem set yet. I will post it as soon as possible, and it won't be due until October 1^st.
• 14-Sept-2001: Class is cancelled today. If you have questions about material or want to talk about anything else, you should be able to find me in my office.
• 10-Sept-2001: My error with Differential Manchester Encoding was simple but fundamental. It does not solve the problem that only half of the available data rate is used. It still yields 1/2 bit per baud. It exists because, for reasons not obvious to me, it performs better than Manchester Encoding in the presence of equivalent noise levels. That the timing information imposes a constraint is not surprising: Transmission of metadata, such as timing, must also consume some amount of the available data rate. Sorry about the confusion!
• 21-Aug-2001: Be sure to check here regularly (that is, daily) to see if there are any important annoucements about the class, assignments, materials, etc.
