摘要： In general, in one aspect, the invention relates to a method for binding input/output (I/O) objects to nodes. The method includes receiving a request to use an I/O device from a process, determining a resource to service the request, generating a first I/O object corresponding to the resource, wherein the first I/O object is unbound, and generating a proc object, wherein the proc object comprises a reference to the process requesting to use the I/O device. The method also includes sending the first I/O object and the proc object to a Non-Uniform Memory Access (NUMA) I/O Framework, determining that the process is executing on a first NUMA node, selecting the first NUMA, binding the first I/O object to the first NUMA node, and servicing the request by processing, on the first NUMA node, the resource corresponding to the first I/O object.
