This paper investigates the achievable uplink spectral efficiency (SE)of a massive multi-input multi-output (MIMO) systems with a mixed analog-to-digital converter (ADC) receiver architecture, in which some antennas are equipped with costly full-resolution ADCs while others are equipped with cheap low-resolution ADCs. We derive the theoretical results and corresponding approximate expressions of the...
Two camps of file systems exist: parallel file systems designed for conventional high performance computing (HPC) and distributed file systems designed for newly emerged data-intensive applications. Addressing the big data challenge requires an approach that utilizes both high performance computing and data-intensive computing power. Thus, HPC applications may need to interact with distributed file...
Faced with mass storage demand in the area of high performance computing, video monitoring, IPTV and multimedia, storage technology have no choice but to be developed rapidly on the basis of current conditions. Network cluster storage technology founded on cluster storage system is most popular storage method to solve mass storage problem at present. Intelligent network disk (IND) is a novel idea...
This paper presents an overview of a control plane architecture for multi-layer, multi-domain networks. Additionally, we report on experiences with implementation, deployment, and use of this architecture on operational networks.
