In a multicore processing system, a method comprising: commencing a time window including at least two time partitions, in a sequence of time windows, wherein the time windows have the same or different durations; determining a shared resource access quota for at least one time partition in the time window , wherein each time partition of the at least one time partition comprises a subset of processes, wherein each time partition is associated with one or more cores of a multicore processor within a time window, wherein the shared resource access quota may vary from time window to time window, and wherein the shared resource access quota of the at least one time partition in the time window is a measure of a number of accesses to shared resources during the at least one time partition in the time window, and wherein the shared resources comprise interconnects, cache memory, memory controllers, at least one data bus, and main memory; allocating each determined shared resource access quota to a corresponding time partition in the time window ; determining if an allocated shared resource access quota of any time partition in the time window has been met or exceeded ; upon determining that an allocated shared resource access quota for a time partition in the time window has been met or exceeded, halting an executing process in the time partition; and upon determining that all of at least one process in a time partition in the time window completed execution without using all of the shared resource access quota allocated to the time partition, allocating the unused shared resource access quota to at least one other time partition in the same time window . commencing a time window including at least two time partitions, in a sequence of time windows, wherein the time windows have the same or different durations; determining a shared resource access quota for at least one time partition in the time window , wherein each time partition of the at least one time partition comprises a subset of processes, wherein each time partition is associated with one or more cores of a multicore processor within a time window, wherein the shared resource access quota may vary from time window to time window, and wherein the shared resource access quota of the at least one time partition in the time window is a measure of a number of accesses to shared resources during the at least one time partition in the time window, and wherein the shared resources comprise interconnects, cache memory, memory controllers, at least one data bus, and main memory; allocating each determined shared resource access quota to a corresponding time partition in the time window ; determining if an allocated shared resource access quota of any time partition in the time window has been met or exceeded ; upon determining that an allocated shared resource access quota for a time partition in the time window has been met or exceeded, halting an executing process in the time partition; and upon determining that all of at least one process in a time partition in the time window completed execution without using all of the shared resource access quota allocated to the time partition, allocating the unused shared resource access quota to at least one other time partition in the same time window . <EOS>
