What is the difference between screensaver, service and command-line versions?
ZetaGrid starts a process to do the calculation on your computer. It can start this process in a number of different ways. The simplest way is that you issue a command, e.g. ‘zeta.sh’ under Linux or ‘zeta.cmd’ / ‘zeta.bat’ under Windows. Then the calculation begins. For your convenience there exist two additional versions for use under Windows. The service is a daemon process which is automatically started whenever you start your Windows NT/2000/XP system. It always runs in the background, so you do not need to manually start the calculation. This is a low priority process (default). The other version is the screensaver. There, Zeta calculation only takes place when the screensaver is active. It is suspended as long as you use the computer. Thus, you do not have any performance effects during your normal work with the computer, but of course the overall calculation speed is slower.
