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.

摘要： Apparatus, methods and computer program products are disclosed for specifying a MAC identifier for a network-interface-device that includes multiple universally administered MAC identifiers and connects to a network through a port. The network-interface-device accepts data packets received through the port if the data packets contain a destination address that matches any active MAC identifier. The method includes reserving a first and second universally administered MAC identifiers from the available universally administered MAC identifiers. The first universally administered MAC identifier and the second universally administered MAC identifier are respectively associated with a first and second resource of the network-interface-device. The MAC identifier is assigned to one of the first or second resource and activated. Other aspects include apparatus logics and program products that perform the method.

摘要： One embodiment of the present invention provides a system that specifies a MAC identifier for a network-interface-device in a computing device. In this system, the network-interface-device is configured to connect to a network though a port. During operation, the network-interface-device receives data packets through this port, and accepts a data packet if the data packet contains a destination that matches the MAC identifier for the network-interface-device, which can be a universally-administered MAC identifier. The system is also configured to determine whether the network-interface-device supports one or more additional MAC identifiers. If so, the system adds and activates an additional MAC identifier. By activating the newly-added MAC identifier in the computing device, the system allows the network-interface-device to logically separate data packets based on MAC identifiers.

摘要： A method for binding input/output (I/O) objects to nodes. The method includes binding an I/O object group to a NUMA node of a plurality of NUMA nodes on a system, obtaining an I/O object group size of the I/O object group, and determining an I/O object group target size based on an I/O object group aggregate load of the I/O object group. The method further includes comparing, by the NUMA I/O Framework, the I/O object group target size and the I/O object group aggregate load, determining, by the NUMA I/O Framework, that a difference between the I/O object group target size and the I/O object group aggregate load exceeds a threshold, and instructing, by the NUMA I/O Framework, an I/O Subsystem associated with the I/O object group to change the I/O object group size, wherein the I/O Subsystem changes, in response to the instruction, the I/O object group size.
