Optimizing General-Purpose CPUs for Energy-Efficient Mobile Web Computing
Yuhao Zhu, Vijay Janapa Reddi
Article No.: 1
DOI: 10.1145/3041024

Mobile applications are increasingly being built using web technologies as a common substrate to achieve portability and to improve developer productivity. Unfortunately, web applications often incur large performance overhead, directly affecting...

Reining in Long Tails in Warehouse-Scale Computers with Quick Voltage Boosting Using Adrenaline
Chang-Hong Hsu, Yunqi Zhang, Michael A. Laurenzano, David Meisner, Thomas Wenisch, Ronald G. Dreslinski, Jason Mars, Lingjia Tang
Article No.: 2
DOI: 10.1145/3054742

Reducing the long tail of the query latency distribution in modern warehouse scale computers is critical for improving performance and quality of service (QoS) of workloads such as Web Search and Memcached. Traditional turbo boost increases a...

Fast In-Memory Transaction Processing Using RDMA and HTM
Haibo Chen, Rong Chen, Xingda Wei, Jiaxin Shi, Yanzhe Chen, Zhaoguo Wang, Binyu Zang, Haibing Guan
Article No.: 3
DOI: 10.1145/3092701

DrTM is a fast in-memory transaction processing system that exploits advanced hardware features such as remote direct memory access (RDMA) and hardware transactional memory (HTM). To achieve high efficiency, it mostly offloads concurrency control...
