If you only have a windows desktop or laptop you have several choices to access TAMNUN or PHELAFEL/PHCLASSES.
Of these options cygwin is the hardest to install, but provides the lightest load communications-wise, especially if working from outside the Technion campus, as you use your local browser, pdf viewer etc. It does mean you need to download then scp files to and from TAMNUN. I am not aware of local support for its use. GoGlobal is the easiest to install.. The TCC provides support so it is recommended for users who require support.
You should now install your selected access tool, and access an account (given in the course for TAMNUN or by the lecturer if you are a physics student), compile and run the surlin.f sample code (or another code of your choice) to check you have mastered the material. Once you have your account and selected your remote access method you should go back to the ``GETTING STARTED'' header on the page about compile/link/run in LINUX.
The final stage for TAMNUN/ALUF only is learning PBS. If you do not have your own program to use to try this out you may download simpson.f and a sample myscript script file. (The program simpson.f is adapted from the interactive routine called chap1b.f described in the numerical quadrature page in week 3 of JA's Computational Physics lectures where a full explanation can be found. It can be made longer by editing the file to increase the value of N.)
For participants in the preliminary course with ALUF accounts course02-course24 a short way to do this is:
cp ~course01/simpson.f .
You then compile it with:
f77 simpson.f -o simpson.ex
and submit to the batch queue with:
qsub -q short myscript
and read the output with
If you run it more than once you will need to remove the output file fort.8 with
before rerunning it.
If you want a test program that runs for even longer then use the file Lsimpson.f and the script Lmyscript.f with the same commands. This program makes a loop over many values of N.
NANCO/TAMNUN users and Technion Physics Department graduate students may contact Dr Joan Adler (phr76ja_at_tx.technion.ac.il) with further questions, OTHERS ARE WELCOME TO USE THE SITE ``AS IS''.
If you have completed all the above tasks you are ready to move to Joan Adler's TAMNUN introduction at http://phycomp.technion.ac.il/~tamnun/tamlearn/tamlearn.html.
