REEF: Retainable Evaluator Execution Framework

by Byung-gon Chun, Chris Douglas, Shravan Narayanamurthy, Josh Rosen, Tyson Condie, Sergiy Matusevych, Raghu Ramakrishnan, Russell Sears, Carlo Curino, Brandon Myers, Sriram Rao, Markus Weimer
"... In this demo proposal, we describe REEF, a framework that makes it easy to implement scalable, fault-tolerant runtime environments for a range of computational models. We will demonstrate diverse workloads, including extract-transform-load MapReduce jobs, iterative machine learning algorithms, and a ..."

, and ad-hoc declarative query processing. At its core, REEF builds atop YARN (Apache Hadoop 2’s resource manager) to provide retainable hardware resources with lifetimes that are decoupled from those of computational tasks. This allows us to build persistent (cross-job) caches and clusterwide services

A complete network-on-chip emulation framework

by N. Genko, D. Atienza, G. De Micheli, J. M. Mendias, R. Hermida, F. Catthoor - In DATE , 2005
"... Current Systems-On-Chip (SoC) execute applications that demand extensive parallel processing. Networks-On-Chip (NoC) provide a structured way of realizing interconnections on silicon, and obviate the limitations of bus-based solution. NoCs can have regular or ad hoc topologies, and functional valida ..."

Semantics and evaluation techniques for window aggregates in data streams

by Jin Li, David Maier, Kristin Tufte, Vassilis Papadimos, Peter A. Tucker - In SIGMOD , 2005
"... A windowed query operator breaks a data stream into possibly overlapping subsets of data and computes a result over each. Many stream systems can evaluate window aggregate queries. However, current stream systems suffer from a lack of an explicit definition of window semantics. As a result, their im ..."

, their implementations unnecessarily confuse window definition with physical stream properties. This confusion complicates the stream system, and even worse, can hurt performance both in terms of memory usage and execution time. To address this problem, we propose a framework for defining window semantics, which can

GraphX: Graph Processing in a Distributed Dataflow Framework

by Joseph E. Gonzalez, et al. - USENIX ASSOCIATION 11TH USENIX SYMPOSIUM ON OPERATING SYSTEMS DESIGN AND IMPLEMENTATION (OSDI ’14) , 2014
"... In pursuit of graph processing performance, the systems community has largely abandoned general-purpose dis-tributed dataflow frameworks in favor of specialized graph processing systems that provide tailored programming ab-stractions and accelerate the execution of iterative graph algorithms. In thi ..."

QACO: Exploiting Partial Execution in Web Servers

by Jinhan Kim, Seung-won Hwang, Sameh Elnikety, Shaolei Ren, Yuxiong He
"... Web servers provide content to users, with the requirement of providing high response quality within a short response time. Meeting these requirements is challenging, especially in the event of load spikes. Meanwhile, we observe that a response to a request can be adapted or partially executed depen ..."

of two modules: (1) A control module adjusts the quota to meet the response time target. (2) An optimization module exploits partial execution and allocates the quota to pending requests in a manner that improves total response quality. We evaluate the framework using a system implementation

Finding Concurrency Bugs with Context-Aware Communication Graphs

by Brandon Lucia, Luis Ceze
"... Incorrect thread synchronization often leads to concurrency bugs that manifest nondeterministically and are difficult to detect and fix. Past work on detecting concurrency bugs has addressed the general problem in an ad-hoc fashion, focusing mostly on data races and atomicity violations. Using graph ..."
