Abstract
A computing device having a non-uniform memory access (NUMA) architecture implements a method to attach a resource to an application instance that is unaware of a NUMA topology of the computing device. The method includes publishing the NUMA topology of the computing device, where the published NUMA topology indicates for one or more resources of the computing device, a NUMA socket associated with each of the one or more resources of the computing device. The method further includes grouping one or more resources that have a same attribute into a resource pool, receiving a request from the application instance for a resource from the resource pool, determining a central processing unit (CPU) assigned to execute the application instance, where the CPU is associated with a NUMA socket, choosing a resource from the resource pool that is associated with a NUMA socket that is closest to the NUMA socket associated with the CPU assigned to execute the application instance, and attaching the chosen resource to the application instance.
