The Case for Energy-Proportional Computing
Luiz Andre Barroso,Urs Hölzle +1 more
TL;DR: Energy-proportional designs would enable large energy savings in servers, potentially doubling their efficiency in real-life use, particularly the memory and disk subsystems.
Proceedings ArticleDOI
B4: experience with a globally-deployed software defined wan
Sushant Jain,Alok Kumar,Subhasree Mandal,Joon Ong,Leon Poutievski,Arjun Singh,Subbaiah Venkata,Jim Wanderer,Junlan Zhou,Min Zhu,Jonathan Zolla,Urs Hölzle,Stephen Stuart,Amin Vahdat +13 more
TL;DR: This work presents the design, implementation, and evaluation of B4, a private WAN connecting Google's data centers across the planet, using OpenFlow to control relatively simple switches built from merchant silicon.
Journal ArticleDOI
Web search for a planet: The Google cluster architecture
TL;DR: Googless architecture features clusters of more than 15,000 commodity-class PCs with fault tolerant software that achieves superior performance at a fraction of the cost of a system built from fewer, but more expensive, high-end servers.
Proceedings ArticleDOI
Jupiter Rising: A Decade of Clos Topologies and Centralized Control in Google's Datacenter Network
Arjun Singh,Joon Ong,Amit Agarwal,Glen Anderson,Ashby Armistead,Roy Michael Bannon,Seb Boving,Gaurav Desai,Bob Felderman,Paulie Germano,Anand Kanagala,Jeff Provost,Jason Simmons,Eiichi Tanda,Jim Wanderer,Urs Hölzle,Stephen Stuart,Amin Vahdat +17 more
TL;DR: This paper built a centralized control mechanism based on a global configuration pushed to all datacenter switches, and modular hardware design coupled with simple, robust software allowed the design to also support inter-cluster and wide-area networks.
Book ChapterDOI
Optimizing Dynamically-Typed Object-Oriented Languages With Polymorphic Inline Caches
TL;DR: PICs provide a new way to reduce the overhead of polymorphic message sends by extending inline caches to include more than one cached lookup result per call site.
