Abstract: A multiprocessor-scalable streaming data server arrangement in a multiprocessor data server having N processors, N being an integer greater than or equal to 2, includes implementing N NICs (Network Interface Cards), a first one of the N NICs being dedicated to receiving an incoming data stream. An interrupt from the first one of the N NICs is bound to a first one of the N processors and an interrupt for an nth NIC is bound to an nth processor, 0<n<=N. A DPC (Deferred Procedure Call) for the nth NIC is bound to the nth processor. M client connections may be tightly coupled to the nth processor via the nth NIC, M being a positive integer. P server threads may be bound to specific ones of a second through N processors. L1 (Level 1) and L2 (Level 2) caches may be defined for each of the N processors, instructions and temporal data being stored in L2 caches of the N processors and non-temporal data being stored in L1 caches of the N processors, bypassing the L2 caches.

Abstract: A method and apparatus for power management is disclosed. The invention reduces power consumption in multiprocessing systems by dynamically adjusting processor power based on system workload. Particularly, the method and apparatus determines the number of required processors based on the number or active threads and sets a processor affinity to run the active threads on the determined number of required processors, thereby allowing the free processors to enter a low-power state.
