Oversubscription of GPU Memory through Transparent Swapping

GPUswap

GPUswap is a modification to the pscnv GPU driver, which enables transparent oversubscription of GPU memory. If applications allocate more GPU memory than available, some application data is transparently moved to system RAM, allowing applications to allocate arbitrary amounts of memory. Since moving data to system RAM causes performance degradation, GPUswap also balances the available GPU memory between applications. For more information, please see our paper at VEE '15.

Building

GPUswap is built along with the rest of pscnv. No special action is required. See README.pscnv for details.
