GPT Versions: Recent GPT versions run under Microsoft-Windows, Linux
and Mac OS X. However, the Linux and Mac releases do
not contain
the graphical 'GPTwin' user interface, and are therefore not able to produce
graphical output. GPT version 3.1 contains a different tracking engine with a new output mechanism as described on our
Features page. Because this substantial rewrite of an essential part of the code can not be easily be merged back into GPT versions 2.8 and 3.0 we decided to stop active development of the 2.8 and 3.0 branches. This is the reason they are not for sale anymore.
More detailed information about the different GPT versions is
shown in the GPT Versions and the GPT platforms tables.
Pricing information can be found in the Pricing table.

2) The
output of GPT can be converted to the SDDS and ASCII formats, for which
excellent plotting packages are available for Linux and Mac. We plan to port
the MS-Windows graphical interface to both Linux and Mac. On-line help is
provided in the form of PDF files of the User Manual.
3) Parameter scans can be distributed automatically over several PC's and/or
over multi-core machines using the MPIMR program. This program is included
in both the Windows and the Linux version of GPT, but requires MPI to be
installed.
