The PAGE system is implemented in Common-Lisp and ANSI C and builds on standardized graphical tookits (the X Window System and Motif) in order to achieve a great degree of portability. In general, it should be possible to port the system to most Un*x workstation for which a suitable Common-Lisp implementation, C compiler, and X and Motif are available; the following combinations of hardware platforms and Common-Lisp implementations (and versions) are known to work and more or less actively maintained:

Allegro CL Lucid CL Macintosh CL
SparcStation; SunOS 4.1.x
SparcStation; Solaris 2.4 or 2.5
HP Prism Architecture; HP-UX 9.x and 10.x
SGI Indigo; Irix 5.2
IBM RS6000; AIX 4.1.3
x86 personal computer; Linux 2.x
Apple Macintosh; MacOS 7.x

As system development at DFKI primarily focusses on Sun workstations and Allegro CL, these are most likely to allow for an easy out-of-the-box installation. For Un*x environments the use of GNU Emacs 19.x is recommended as a frontend to the Common-Lisp systems; Allegro CL comes with a propietary, fully integrated Emacs interface while Lucid CL (at least as of version 4.1) is best embedded into Emacs by virtue of the ilisp package available from the public domain..

The PAGE resource consumption and performance heavily depends on, among others, grammar and lexicon size. For serious grammar engineering purposes a powerful cpu (> 60 SPECint), at least 50 MByte of disk space, and a minimum of 64 MByte of main memory are required. Processing times (e.g. using the DFKI grammar for German or the VerbMobil HPSG of English) on a SparcStation 5 range from a few seconds to around one minute for average length sentences (10 words).
