<p>A parallel computer includes a plurality of processors (4) and respectively associated dedicated local storage (6), at least one system controller (13), an interprocessor communications channel (IPC) (16) interconnecting the processors under the control of a particular system controller and a controller communication channel (20) interconnecting the system controller and the processors under its control. Each of the processors includes a principal processing element (PPE) (285) and a memory control unit (230). The PPE is adapted to execute program sequences of instructions, which instructions include local-storage-access instructions for accessing information in the dedicated local storage, and to generate a PPE access-priority-state signal for signaling that the PPE is in an access-priority state defined in conjunction with an access to the dedicated local storage by the PPE. Access to the dedicated local storage from a plurality of information resources is controlled by the memory control element in response to a dedicated local storage enable signal generated at the time program sequences of instructions are complied.</p> |
