Abstract
One or more embodiments of the invention set forth techniques to allocate a memory buffer in the system memory of a computer system that is shared among a plurality of graphics processing units (GPUs) in the computer system. The GPUs are able to engage in Direct Memory Access (DMA) with the memory buffer thereby eliminating additional copying steps that have been needed to combine data output of the various GPUs without such a shared memory buffer.
