Abstract
Task management in a Non-Uniform Memory Access (NUMA) architecture having multiple processor cores is aware of the NUMA topology in task management. As a result memory access penalties are reduced. Each processor is assigned to a zone allocated to a memory controller. The zone assignment is based on a cost function. In a default mode a thread of execution attempts to perform work in a queue of the same zone as the processor to minimize memory access penalties. Additional work stealing rules may be invoked if there is no work for a thread to perform from its default zone queue.
