What means Linux Single User?

The Linux Single User license means that Phonon software may be used only by a single User on a single processor, in practice on personal computer. The computing CPU time of Phonon's option, for problems treated by ab initio codes, last typically seconds, thus there is no need to install Phonon on Computer Cluster or in Computer Center. Phonon is protected by a dongle, however, it may be installed on computers of Users of the same Research Group of the same Institution. Unfortunatelly it means that at any one time Phonon can be used by one User only. Users are not allowed to transfer the Software to another Group, or Institution.
