GPT Versions: All 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. The main feature of GPT version 3.1 is a different tracking engine with significantly faster and more accurate output. Our multi-objective genetic optimizer was first introduced in GPT version 3.2 and the main addition to the 3.3 release are wakefields and CSR capabilities. GPT version 3.5 includes spin tracking and performance enhancements such as memory-mapped 3D field-maps.

1) Sold as a seperate product for electron microscopy applications.
2) The Linux and Mac versions of GPT do not ship with a graphical user interface. We therefore recommend converting GPT and GDFA output to ascii or SDDS, and subsequently using public domain plotting packages such as GNUplot and the SDDStoolkit. Alternatively, scripts are available on the GPT Community page that convert binary output to Matlab and HDF formats. On-line help is always available as PDF manuals.
3) Running the MPI-cluster version requires one 'per machine' license for that machine in addition to an individual 'per user' GPT license for each active GPT user.
4) Default OS is CentOS7. Distributions for other systems can be created upon request.
