A generic NUMA-compliant memory selection technique is provided to enable a device capable of accessing memory anywhere in a system to select a near (potentially the nearest) memory for use with the device. For example, an AGP controller can access system memory anywhere within a multiprocessing node system, but will operate more efficiently, and interfere less with other data transactions, if it locates the closest memory, determines the memory addresses corresponding to the closest memory, and locks (or otherwise allocates) memory addresses for AGP functionality within the range of determined addresses in the near memory.

Faster memory access in non-unified memory access systems

The present application describes a system and method of profiling a computer system based on a profiling state machine. The profiling state machine defines various states in which the system data can be collected for a particular application. The state machine allows system data collection regardless of timing intervals or event counters. When a state is identified for system data collection, the profiler application collects system data for the user. A profiling application driver monitors the state machine and manages the data collection based on the state machine. The profiling application driver controls the profiling configurations thus allowing a correlated data collection for timing intervals and event counter.
