Abstract: In one embodiment, a computer system, comprises at least a first computing cell and a second computing cell, each computing cell comprising at least one processor, a routing device to couple the first and second computing cells, a global clock signal source coupled to the at least two computing cells to generate a global clock signal, at least one timing manager to generate a timing control signal, wherein the at least two computing cells comprise a local oscillator to generate a local clock signal, and a multiplexer coupled to receive the global clock signal, the local clock signal, and the timing control signal, and to output one of the global clock signal or the local clock signal in response to the control signal.

Abstract: There is provided a method of operating a computer system. The computer system comprises at least two cabinets and the at least two cabinets have at least one clock signal. The method includes selecting one of the at least one clock signal to serve as a master signal, and synchronizing the computer system to operate from the master signal. Additionally, the method includes altering the capacity of the system while the system is operating.
