Abstract: Methods, systems, and articles of manufacture for maintaining a virtual counter in a logically partitioned computer system are described. The virtual counter may be based on a remote counter. For some embodiments, while a reset to the remote counter is not in progress, a value of the virtual counter generated based on the remote counter, as well as a current value of an independent counter (e.g., running independently of the remote counter and not affected by a remote counter reset) is stored. While a reset to the remote counter is in progress, an estimated value of the virtual counter may be generated based on the previously stored value of the virtual persistent clock, the previously stored value of the independent counter, and a current value of the independent counter.
