PEPSY works on the computers of the CIP-Pool and the sun workstations of Informatik 4. All users with a valid account on one of these machines can use PEPSY.
The program package is distributed via the automounter, the directory is /local/pepsy. This directory is the so-called PEPSYHOME. The programm binaries are in the subdirectory bin, which has to be included in your searchpath. Additionally the environment variable PEPSYLANG has to be set, because PEPSY allows the use of english, german and hungarian language. The following lines have to be included in the .cshrc file in your HOME-directory:
setenv PEPSYHOME /local/pepsy
setenv PEPSYLANG englisch
setenv MANPATH /usr/man:/local/man:$PEPSYHOME/man
set path=($path $PEPSYHOME/bin)
Important commands of PEPSY-QNS are eingabe (input), auswahl (selection) and analyse (analysis). After you start the programm eingabe on the command line you can interactively enter the parameters of the net and save the data to e.g. filename. Then you have to find out which analysis routines can be used with your net. You do this by typing in auswahl filename. After this you execute the analysis of the model with the command analyse routine filename. The results are shown on the screen and stored in a file.
If you type pinfo you get a list of all collected routines. Detailed information can be obtained via pinfo routine.
Further exists a GUI, xpepsy, which comprises all functionality from generating a net to analysing it.
There are manpages for the most important commands: pepsy(1), eingabe(1), auswahl(1), analyse(1), pdiff(1), pcheck(1), pls(1), transform(1), zusatz(1).
