Theory Computing Environment

Linux Cluster

The Linux machines are named tppc11, tppc12, tppc13, tppc15 and tppc16. The members of the Theory Group can login directly into these machines from their X-Terminal or with telnet, rsh from other machines.

The home directories of user johndoe at the Computing Centre's AIX- and Linux-Cluster are mounted on

/RZ_AIX_U/johndoe /RZ_LNX_U/johndoe

If John Doe has separate home directories on the Theory Clusters these are accessible as

/THE_AIX_U/johndoe /THE_LNX_U/johndoe

Ask Jörn Knoll or Thomas Neff, if you want separate home directories on the Theory Clusters.

The home directory on the Theory Linux Cluster

/u/johndoe

is then a link to /RZ_LNX_U/johndoe or /THE_LNX_U/johndoe.

Software

We provide a great range of software on our Linux machines. Only a subset of the installed software is mentioned here. Follow the links to get more documentation about the mentioned programs.

Besides the usual shells ksh, csh and bash, the scripting languages perl, python and tcl are available for scripts.

For program development we provide compilers for C/C++ (gcc and g++) and Fortran 77 (g77).

The Batch System DQS should be used for long running non-interactive jobs.

For Mathematics you can use Mathematica. There is also a free product called MuPad. Octave ist a Matlab clone suited for numerical work.

Editing bitmap graphics is a job for gimp or xpaint. Vector graphics can be done with xfig. For scientific diagrams you can use IDL, xmgr or gnuplot.

Typesetting in the physics world is a synonym for tex or latex. We use the very complete teTeX distribution.

Communication with the rest of the world is done by email (mail, elm, emacs, netscape), news (emacs gnus, knews, netscape) and surfing (lynx, netscape).

For those of you prefer a click-oriented work-style on your desktop we have KDE and tkdesk.
