Variable credit per work unit
BOINC assigns a variable amount of credit per completed work unit, based on your CPU speed and the CPU time used.
Highly configurable preferences
You have more control over how your computer is used: for example, you can limit the disk usage, the network bandwidth, and the work hours. You can also control the amount of work that your computer downloads each time it connects to our server. These 'preferences' are managed using a web-based interface, and they automatically are applied to all the computers on which you run SETI@home.
SETI@home's graphics now have a modern 3-D look. When they're running in a window, you can use the mouse to rotate and zoom. You can even customize the graphics using a web-based interface.
