Grading policy

Dear students,

I have clarified with the Registrar that the class can be taken either for a letter grade, or P/F. So, if you are taking it for credit, please email me:

Your name, option, and whether you want a letter grade or P/F

And, just in case you are wondering, the grading will be as follows: I will assume that the honor system is working, and that you have done all of the assignments and suggested exercises and readings. Thus everyone gets an A or a P, and now you can stop worrying about grades, and focus on learning! (In case someone believes that they do not deserve such a grade, please let me know, and I'll give you the grade you think you deserve....)

Thanks, George

Hamming numbers

Hi all,

I was wondering if we could start a discussion on the assignment of Lecture 2 (computing Hamming numbers in 3 different languages). I have gone ahead and used Matlab, Fortran95 and Python. I have the following questions:

* How do you test memory usage for codes such as Python, C, Fortran, Matlab?
* Is there a particular code profiling tool for Linux and/or (Intel) Mac OS X that people can recommend?

I would be interested in any comments, ideas and findings!
