DRAGON: Direct Resource Access for GPUs Over NVM

DRAGON is a host-based framework that transparently extends the GPU addressable global memory space beyond the host memory using NVM-backed data pointers. DRAGON allows storing the binary memory dump of application data in a file on NVM and mapping it to the global memory space of the GPU. This enables GPU kernels to access the data via regular load/store instructions, similar to how mmap() operates in CPUs.
