Taming Latency in Data Center Networking with Erasure Coded Files

Yu Xiang, Vaneet Aggarwal, Yih-Farn R. Chen, Tian Lan
2015 2015 15th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing  
This paper proposes an approach to minimize service latency in a data center network where erasure-coded files are stored on distributed disks/racks and access requests are scattered across the network  ...  The results provide valuable insight on designing low-latency data center networks with erasure-coded storage. 2015 15th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing 978-1-4799  ...  With knowledge of the access patterns of different files, the use of erasure coding enables a novel latency optimization of data center storage with respect to placement of erasure coded content Y.  ...

Problems in Modern High Performance Parallel I/O Systems [article]

Robert Louis Cloud
2011 arXiv   pre-print
In addressing the two prior issues, one must also question the nature of the data itself; one can ask whether contem- porary practices of data dumping and analysis are optimal and whether they will continue  ...  For a variety of reasons, the I/O subsystems of such computers have not kept pace with the computational increases, and the time required for I/O in an application has become one of the dominant bottlenecks  ...  erasure codes(typical RAID-like parity byte encoding).  ...

Pelican: A Building Block for Exascale Cold Data Storage

Shobana Balakrishnan, Richard Black, Austin Donnelly, Paul England, Adam Glass, David Harper, Sergey Legtchenko, Aaron Ogus, Eric Peterson, Antony I. T. Rowstron
2014 USENIX Symposium on Operating Systems Design and Implementation  
We show that compared to this over-provisioned storage rack Pelican performs well for cold workloads, providing high throughput with acceptable latency.  ...  A significant fraction of data stored in cloud storage is rarely accessed. This data is referred to as cold data; cost-effective storage for cold data has become a challenge for cloud providers.  ...  It uses two servers connected using dual 10 Gbps Ethernet ports to the data center network, providing an aggregate of 40 Gbps of full-duplex bandwidth.  ...

Approximate Networking for Universal Internet Access

Junaid Qadir, Arjuna Sathiaseelan, Umar Farooq, Muhammad Usama, Muhammad Imran, Muhammad Shafique
2017 Future Internet  
The overwhelming focus of the Internet research community has been on improving the ideal networking experience by providing increasingly higher throughputs along with lower latencies.  ...  We see this in wired technologies such as the modern fiber-based broadband high-speed network, which come close to providing "ideal network" performance, have largely been restricted to urban centers and  ...  on cloud data centers with the increased adoption of cloud computing and NFV.  ...

Implementing statically typed object-oriented programming languages

Roland Ducournau
2011 ACM Computing Surveys  
In statically typed object-oriented languages, message sending, or late binding, is implemented with tables often called virtual functions tables (VFT).  ...  Those tables reduce method calls to function calls, with a small fixed number of extra indirections. The overhead is more or less important, whether inheritance and subtyping are single or multiple.  ...  in the code or in the data structures.  ...

Noisy Fields: Interference and Equivocality in the Sonic Legacies of Information Theory

Learning Race and Ethnicity: Youth and Digital Media

As with earlier shifts in media environments, this current turn toward digital media and networks has been accompanied by fear and panic as well as elevated hopes.  ...  Digital media networks support existing forms of mass media distribution as well as smaller publics and collectivities that might center on peer groups or specialized niche interests.  ...  These phrases, while somewhat derogatory in nature, are intended only as a slang means of expression that can be generally accepted by everyone in an effort not to offend or incite, and are not aimed at  ...

We study the never-worse relation (NWR) for Markov decision processes with an infinitehorizon reachability objective.  ...  Using the NWR, states in the same equivalence class can be collapsed. Then, actions leading to sub-optimal states can be removed. Our main results are as follows. 1.  ...  The repair problem refers to correcting one or several erasures with a given error-correcting code using as little inter-nodal communication as possible.  ...
