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.

Using process location to bind IO resources on NUMA architectures

In accordance with one embodiment of the present invention, there is provided a mechanism for implementing transfer of arbitrary length messages between one or more machines in a computing environment comprised of a plurality of machines. With this mechanism, it is possible to send and receive messages of arbitrary length across memory-based or other interconnects using a single operation. In one embodiment, the machines are interconnected by a memory-mapped link. The memory-mapped link includes processes for mapping an image of a buffer allocated in the storage of the receiving machine into the addressing space of the sending machine. The sending machine may transfer the message to the memory of the receiving machine using a single write operation to the memory mapped image in the sending machine's own address space.

Transfer of arbitrary size messages over memory based interconnects

A device driver interface for achieving portability of device drivers for operating with full source level compatibility across multiple instruction set architectures and platforms. The device driver interface makes transparent to the driver the actual data access mechanisms of the host computers on which the driver is compiled.
