Introduction to Computational Physics

Before the class starts:

OPENING COMPUTER ACCOUNTS:
  1. Course work for this class will be done on phelafel and phclass1-5, LINUX computers in Rm 315, or elsewhere after OK from Dr Adler.
  2. BUT, every student in this course must have an account on TX (graduates) or T2 (undergraduates), before we will open accounts on phelafel. You should have received forms for T2/TX accounts on enrolment, they are the machines on which you once got your e-mail, but are now mainly used to enter thru the Technion firewall. This account that has an address of YOURNAME@tx.technion.ac.il (or at t2.technion.ac.il is also an account on a computer called aluf.technion.ac.il that is a LINUX computer you can log onto and run programs, latex etc on it. All programs needed for this class are installed there. Unlike the computer physics that is meant for websites and mail aluf is meant to run things on too, although there is an interactive time limit. Physics graduate students should ask the Physics Department software engineer Riva in Rm 454 for help with their tx or physics accounts if they need it.
  3. Once your TX/T2 account has been opened you may link to the phelafel website and follow the instructions to open your an account on phelafel.
  4. VERY IMPORTANT! you can log on to phelafel and the phclasses from anywhere in the Technion (including TX/T2) so you MUST NEVER switch them off!!!!! because someone else may want to log in from remote.

ACCESS TO ROOM 315: see above - you need to get a key from Avi or Misha.

QUESTIONS: If you have a question about the course please read the frequently asked questions FAQs page and if the answer is not there email Dr Joan Adler. If I think an answer is of interest to others I will add it to the FAQs.

FIRST WEEK: BACKGROUND MATERIAL FOR COMPUTATIONAL PHYSICS
  1. History: this seems to include also the computers used for the course a few years ago. The big question is whether the lecturer is also already part of history??? more details
  2. Hardware: a discussion about different types of computer architectures, printers, switches and modems. more details
  3. Software: operating systems, languages, compilers, graphics formats, libraries, output drivers, word processors and software issues such as public domain and site-licenses. What software is on PHELAFEL and how to set up your account there and compile simple fortran programs. more details
  4. Communications: TCP/IP protocols, ethernet etc, accessing PHELAFEL from remote. We will make a class email list. more details
  5. Manuals and Consultants: on any UNIX system, to get information about a command (e.g. ssh) try to type ``man ssh''. Different software packages have their help files in different places, but, in general, lots of good information and help for Technion graduate students with computing matters related to their RESEARCH can be found from the Computer Center consultants. more details
  6. The Web: an introduction to the web and some websites that are relevant to this course. Preparing your own homepage, to be listed on the class website list.

At the start of the next lecture I might ask short oral questions about the material on the pages linked in the section above. So please think now if there was anything you did not understand and see the sample questions.

Check out the commands page for helpful advice.


The targil for the first week is to download, compile, and run the file sur2016.f which can be found here . See the commands page for how to compile fortran.

Extra help for the targil.

You must also get a key to Rm 315, get your account(s) opened and get your web browser sorted out ready for the next lecture in rm 315. If you need information on an editor check out Riva's guides.


ROOM 315:
  • See MAP of Rm 315 and view connections under the desks, internet cables are in the cupboard.
  • Phelafel and phclass1-5 are for your use during this course and for general interactive use for new Physics MsC students who do not yet have a supervisor and for project students.
  • Reference material for later lectures and all targilim will be listed here.

    Check that you do the following before the next class:
    1. Register on the LISTSERV - http://tx.technion.ac.il/archives/ph118094W-l.html - this does not register you to course or oblige you to register - it does get you all emails about the course and helps me allocate a computer.
    2. Get key to Rm 315 from Avi or Misha.
    3. Print, complete and place in my letterbox the registration form for an account on phelafel/phclass.
    4. Download the homework exercise, do it, hand in ``printed'' version and email the output file to me at phr76ja@tx.technion.ac.il
    Students who missed the first lecture must do the 4 items here before the next class if they wish to join it.


    Please also view details about the Undergraduate Computational Physics Projects and projects from recent sessions of this course.
