Dynamic balancing of io resources on numa platforms

A system, comprising:

• a plurality of Non-Uniform Memory Access (NUMA) nodes comprising:
• a first NUMA node comprising a first processor and a first memory;
• a second NUMA node comprising a second processor and a second memory;
• an input/output (I/O) device group comprising an I/O device;
• an I/O Subsystem executing on at least one of the plurality of NUMA nodes, configured to:
• receive a request to use the I/O device from a process executing on the first NUMA node;
• determine a first resource necessary to service the request;
• and
• generate a first I/O object corresponding to the first resource, wherein the first I/O object is unbound;
• and
• a NUMA I/O Framework executing on at least one of the plurality of NUMA nodes, configured to:
• receive the first I/O object from the I/O Subsystem;
• obtain a first I/O object effective load from the first I/O object;
• obtain a first I/O load capacity of the first NUMA node;
• obtain a second I/O load capacity of the second NUMA node;
• compare the first I/O load capacity and the second I/O load capacity to the first I/O object effective load;
• select the second NUMA node based on a determination that the second I/O load capacity is greater than the first I/O object effective load;
• and
• bind the first I/O object to the second NUMA node,
• wherein the request is serviced by processing, on the second NUMA node, the first resource corresponding to the first I/O object.

A method for binding input/output (I/O) objects to nodes, the method comprising:

• receiving, by a Network Media Access Connection (MAC) Layer, a request to create a data link from a process, wherein the Network MAC Layer is associated with a physical network interface card (NIC);
• determining, by the Network Mac Layer, a thread to service the request;
• generating, by the Network Mac Layer, a first I/O object corresponding to the thread, wherein the first I/O object is unbound;
• sending, by the Network Mac Layer, the first I/O object to a Non-Uniform Memory Access (NUMA) I/O Framework;
• obtaining, by the NUMA I/O Framework, a first I/O object effective load from the first I/O object;
• obtaining, by the NUMA I/O Framework, a first I/O load capacity of a first NUMA node of a plurality of NUMA nodes;
• comparing, by the NUMA I/O Framework, the first I/O load capacity and the first I/O object effective load;
• selecting the first NUMA node based on a determination by the NUMA I/O Framework that the first I/O load capacity is greater than the first I/O object effective load;
• binding, by the NUMA I/O Framework, the first I/O object to the first NUMA node;
• and
• servicing the data link by executing, on the first NUMA node, the thread corresponding to the first I/O object.
