Starling: A Scalable Query Engine on Cloud Function Services [article]

Matthew Perron, Raul Castro Fernandez, David DeWitt, Samuel Madden
2019 arXiv   pre-print
In this paper we present Starling, a query execution engine built on cloud function services that employs number of techniques to mitigate these challenges, providing interactive query latency at a lower  ...  In particular, on a 1TB TPC-H dataset in cloud storage, Starling is less expensive than the best provisioned systems for workloads when queries arrive 1 minute apart or more.  ...  CONCLUSION In this paper we presented Starling, a query execution engine for data analytics built on cloud function services.  ...

Linked open data to represent multilingual poetry collections. A proposal to solve interoperability issues between poetic repertoires

Elena González-Blanco, Gimena del Rio, Clara Martínez Cantón
2016 Zenodo  
Th is paper describes the creation of a poetic ontology in order to use it as a basis to link different databases and projects w orking on metrics and poetry.  ...  It has been built on the model of the Spanish digital repertoire ReMetCa, but its aim is to be enlarg ed and improved in order to fit under every poetic system.  ...  Since 2013, our work on OLiA has been partially supported by the LOEWE cluster "Digital Humanities" at the Goethe-University Frankfurt (2011-2014) and a DFGfunded project on a Virtual Library for General  ...

Self-Organization and Resilience for Networked Systems: Design Principles and Open Research Issues

Simon Dobson, David Hutchison, Andreas Mauthe, Alberto Schaeffer-Filho, Paul Smith, James P. G. Sterbenz
2019 Proceedings of the IEEE  
It is almost inconceivable to contemplate a future without even more dependence on them. Indeed, any unavailability of such critical systems is-even for short periods-a rather bleak prospect.  ...  This will be achieved, on the one hand, through the (self-)adaptation of networked systems and, on the other Manuscript hand, through structural and operational resilience techniques to ensure that they  ...  One area of possible interest would be building and maintaining an SA city database that can be queried by various applicationsincluding ones that try to keep an eye on resilience, e.g., as proposed in  ...

Towards Demystifying Serverless Machine Learning Training [article]

Jiawei Jiang, Shaoduo Gan, Yue Liu, Fanlin Wang, Gustavo Alonso, Ana Klimovic, Ankit Singla, Wentao Wu, Ce Zhang
2021 pre-print
The appeal of serverless (FaaS) has triggered a growing interest on how to use it in data-intensive applications such as ETL, query processing, or machine learning (ML).  ...  We present a design space covering design choices such as optimization algorithms and synchronization protocols, and implement a platform, LambdaML, that enables a fair comparison between FaaS and IaaS  ...  We then implemented LambdaML, a prototype system of FaaS-based training on Amazon Lambda, following which we systematically depicted the tradeoff space and identified cases where FaaS holds an edge.  ...

Utility-based Allocation of Resources to Virtual Machines in Cloud Computing

Dorian Minarolli
2014
In recent years, cloud computing has gained a wide spread use as a new computing model that offers elastic resources on demand, in a pay-as-you-go fashion.  ...  To allocate multiple resources at the local physical machine level, a solution based on feed-back control theory and utility function optimization is proposed.  ...  scalability of the resource management in a large scale cloud infrastructure.  ...

The motivation for this seminar was to showcase recent progress in these different areas with the goal of working towards a common basis of understanding, which should help to facilitate future synergies  ...  This yields both an implicit characterization of polynomial time in terms of ordinary differential equations, and a completeness result on the reachability problems for the corresponding class.  ...  We prove that a particular class of ordinary differential equations (ordinary differential equations with polynomial right hand side) can be solved in polynomial time.  ...
