The advent of many core era breaks the performance wall but it causes severe energy consumption. NVRAM as a main memory can be a good solution to reduce energy consumption due to large size of DRAM. In this paper, we propose MN-MATE, a novel architecture and management techniques for resource allocation of a number of cores and large size of DRAM and NVRAM. In MN-MATE, a hyper visor partitions and allocates cores and memory for guest OSes dynamically. It is clear that optimized matching of heterogeneous cores, DRAM, and NVRAM enhances system performance. Selective locating of data in a main memory composed of DRAM and NVRAM significantly reduces energy consumptions. Preliminary results show that integration of dynamic resource partitioning and selective memory allocation scheme with MN-MATE reduces energy usage significantly and suppresses performance loss from NVRAM's characteristics.
