Abstract
One or more embodiments of the invention set forth techniques to create a process in a graphical processing unit (GPU) that has access to memory buffers in the system memory of a computer system that are shared among a plurality of GPUs in the computer system. The GPU of the process is able to engage in Direct Memory Access (DMA) with any of the shared memory buffers thereby eliminating additional copying steps that have been needed to combine data output of the various GPUs without such shared access.
