Dynamic Partitioned Global Address Spaces (DPGAS) is an abstraction that allows for quick and efficient remapping of physical memory addresses within a global address space, enabling more efficient sharing of remote DRAM. While past paper has proposed several uses for DPGAS, the most pressing issue in today's data centers is reducing power. This paper uses a detailed simulation infrastructure to study the effects of using DPGAS to reduce overall data center power through low-latency accesses to \"Virtual\" DIMMs.
