SciHadoop: array-based query processing in Hadoop
Joe Buck,Noah Watkins,Jeff LeFevre,Kleoni Ioannidou,Carlos Maltzahn,Neoklis Polyzotis,Scott A. Brandt +6 more
TL;DR: This work describes the implementation of a Sci-Hadoop prototype for NetCDF data sets and quantifies the performance of five separate optimizations that address the following goals for several representative aggregate queries: reduce total data transfers, reduce remote reads, and reduce unnecessary reads.
Proceedings ArticleDOI
The Popper Convention: Making Reproducible Systems Evaluation Practical
Ivo Jimenez,Michael A. Sevilla,Noah Watkins,Carlos Maltzahn,Jay Lofstead,Kathryn Mohror,Andrea Arpaci-Dusseau,Remzi H. Arpaci-Dusseau +7 more
TL;DR: This paper introduces _Popper_, a convention based on a set of modern open source software development principles for generating reproducible scientific publications that leverages existing cloud-computing infrastructure and DevOps tools to produce academic articles that are easy to validate and extend.
Proceedings Article
Flash on rails: consistent flash performance through redundancy
TL;DR: Rails is proposed, a design based on redundancy, which provides predictable performance and low latency for reads under read/write workloads by physically separating reads from writes, and achieves read-only performance while writes perform at least as well as before.
Proceedings ArticleDOI
Mantle: a programmable metadata load balancer for the ceph file system
Michael A. Sevilla,Noah Watkins,Carlos Maltzahn,Ike Nassi,Scott A. Brandt,Sage Weil,Greg Farnum,Sam Fineberg +7 more
TL;DR: A programmable storage system that lets the designer inject custom balancing logic is introduced that shows the flexibility and transparency of this approach by replicating the strategy of a state-of-the-art metadata balancer and concludes by comparing this strategy to other custom balancers on the same system.
Proceedings ArticleDOI
Malacology: A Programmable Storage System
Michael A. Sevilla,Noah Watkins,Ivo Jimenez,Peter Alvaro,Shel Finkelstein,Jeff LeFevre,Carlos Maltzahn +6 more
TL;DR: This work introduces the programmable storage approach, which exposes internal services and abstractions of the storage stack as building blocks for higher-level services, and illustrates the advantages and challenges of this approach by composing existing internal abstractions into two new higher- level services.
