HiKV, a persistent key-value store with the central idea of constructing a hybrid index in hybrid memory, exploits the distinct merits of hash index and B+-Tree index and adopts ordered-write consistency to ensure crash consistency.
Power--Aware Performance Adaptation of Concurrent Applications in Heterogeneous Many-Core Systems
- Ali Aalsaud, R. Shafik, A. Rafiev, F. Xia, Sheng Yang, A. Yakovlev
- Computer ScienceInternational Symposium on Low Power Electronics…
- 8 August 2016
A novel runtime optimization approach with the aim of achieving maximized power normalized performance considering dynamic variation of workload and application scenarios is proposed and it is demonstrated that it is possible to continuously adapt system configuration through a low-cost and linear-complexity runtime algorithm, which can improve the IPS/Watt by up to 125% compared to the existing approach.
