Windows or Linux Phonon version?

Windows

Windows Phonon ver. 5.10. 5.11 use a dongle which must be plugged-in to USB port. No driver need to be installed. Phonon consists practically of a single executable file, so one clicks the icon and makes Phonon running.
All results produced by Phonon are text files. Phonon can be used on your second computer in the sense that you take off the dongle from the first computer, and plug it into another computer. Then you need to copy only text files of your project and you may continue to work.
Ab initio calculations must be trasfered from linux to windows platform. There are a few programs which facilitates this process.

Linux

Due to many linux kernels and fast change of linux versions it might happen that not all Phonon Software options run properly on linux platforms. However, to minimize the risk we advice to run the Demo-Phonon for Linux, which runs only a few examples, but uses all needed libraries.
Phonon for linux has three stages of statically linked libraries. Be sure that one of them works properly.
Linux Phonon ver. 5.10 uses a dongle which must be plugged-in to USB port. No driver need to be installed, except to activate the port. Phonon consists practically of a single executable file, so one runs it from the terminal.
All results produced by Phonon are text files. Phonon can be used on your second linux computer in the sense that you take off the dongle from the first computer, and plug it into another linux computer. Then you need to copy only text files of your project and you may continue to work. Some advantage is that ab initio calculations can be done on the same linux platform.
