Abstract

Embodiments that facilitate the fair and dynamic distribution of central processing unit (CPU) time are disclosed. In accordance with one embodiment, a method includes organizing one or more processes into one or more groups. The method further includes allocating a CPU time interval for each group. The allocation of a CPU time interval for each group is accomplished by equally distributing a CPU cycle based on the number of groups. The method also includes adjusting the allocated CPU time intervals based on a change in the quantity of the one or more groups.
