TEACHING

The high-light: The decade-long teaching effort in the programming language FORTRAN, still an important tool in (Computational) Physics, was honored by the computer company COMPAQ by donating us (as part of the University of Vienna) their program package VISUAL FORTRAN

http://www.COMPAQ.com/FORTRAN/visual/donation-thanks.html

which we will start to use in 2001/02. It allows teaching FORTRAN in a "standard" Windows Integrated Development Environment (like the MS-Visual Compilersuite today in use) and gives compatibility to normal command line mode, common libraries and FORTRAN extensions ("COMPAQ FORTRAN" is successor of "DIGITAL FORTRAN" and might soon be "INTEL FORTRAN").

This donation, which also includes a limited number of student versions, coincides with the change of the physics curriculum at the University of Vienna making Computational Physics mandatory for physics beginners.

In the past (29th) year of teaching Computer Sciences the volume of formal teaching was decreased to 48 hours (Semesterwochenstunden). This reduction was due to the termination of "Universitätslehrgang Informatik" which was strongly supported by our teaching efforts. Disregarding basic and general subjects other highlights were, like in the previous year,

Parallel computing: Arbeiten an Parallel-Computern (Workstation-Cluster unter MPI)

UNIX: Internet-Werkzeuge (LINUX und JAVA)

Fuzzy Logic: Einführung in die Fuzzy Logic und ihre Anwendung in der Robotik

Internet: Datenverkehr über Computernetze (Netzaufbau, Protokolle, etc.) Publizieren im Internet (Suchmaschinen, HTML, XML, etc.)

graphics: Visualisierung naturwissenschaftlicher Daten and

our only hardware course: Mikroelektronik in der Prozeßsteuerung.

The general programming languages in use were FORTRAN-90, C, ECANSE and JAVA.

To improve and streamline the computational science part of the physics curriculum we started to teach both FORTRAN and C in one class (UE 2 hours, Lektor Penits) and created a new lecture (for our science freshmen) called "Scientific computing" (VO+UE 4 hours, Prof. Neumann, Dr. Karch), stressing programming languages (FORTRAN, C, Mathematica), basic algorithms (from simple equations through Monte Carlo applications) and various skills (UNIX,Gnuplot,LATEX). A script for this course can be found in the tutorial section of our web-server (http://www.exp.univie.ac.at/inst/skripten.html).

Like in the past, the majority of courses were held by external lecturers so that new developments could be covered sooner. Additional physics connected teaching of computer sciences was done by the Computational Physics Group and within the general curriculum of physics students.

The local PC Class Room Web-Server was dramatically downgraded due to a lack of accessibility from outside. It is now behind a firewall making students' homework via Internet a lot more inconvenient. In this PC Class Room 14 PCs are connected under Novell NetWare 4.x working alternately under the operating systems MS-DOS, Windows NT or LINUX. During the reporting period some of the hardware was updated. At the end of the recording period a Philips Multimedia Projector (or Videobeamer) was added with XGA-Resolution and 1500 ANSI Lumen.

The Workstation ClassRoom in the building Sensengasse 8 is used for Practical Courses, and for Diploma works in the field of Computational Physics. There are two clusters with classical "workstations" available: a DEC Alpha-Cluster with a DEC 3000-400 and five DEC 3000-300Ls under OpenVMS, and a DEC VAX-Cluster with two VAXstations 4000-60 under VMS. However, teaching there is now mainly done under a PC-based double processor LINUX Computer.

Aside from the local computers, those of the local branch of the Central Computing Division of the University of Vienna (AP des ZID der Universität Wien) running under UNIX, or any other computer accessible via INTERNET (like the OPEN-VMS cluster of the Institute) are available for all students working either in the PC Class Room or the Workstation Class Room.

WWW-Server of the Institute: Since March 1995 the Institut für Experimentalphysik has been present in World Wide Web (WWW) with the address:

http://www.exp.univie.ac.at

This service was made possible by the endeavor of Prof. Neumann who is still in charge of it and who is spending some of his valuable time on rather frequent updates of it.
