Embedding GPU Computations in Hadoop

Jie Zhu, Hai Jiang, Juanjuan Li, Erikson Hardesty, Kuan-Ching Li, Zhongwen Li
2014 International Journal of Networked and Distributed Computing (IJNDC)  
To utilize GPU in Hadoop, four approaches including Jcuda, JNI, Hadoop Streaming, and Hadoop Pipes, have been accomplished and analyzed.  ...  Hadoop schedules MapReduce's Map and Reduce functions across multiple different computing nodes through Java, whereas CUDA code helps accelerate local computations further on attached GPUs.  ...  Unlike Hadoop streaming, Hadoop Pipes connect JVM and C/C++ code through a Socket rather than a JNI, as shown in Fig. 8 and 9 .  ...

Analysing the performance and costs of reactive programming libraries in Java

Julien Ponge, Arthur Navarro, Clément Escoffier, Frédéric Le Mouël
2021 Proceedings of the 8th ACM SIGPLAN International Workshop on Reactive and Event-Based Languages and Systems  
This paper discusses the performance of the three major reactive streams compliant libraries used in Java applications: RxJava, Project Reactor, and SmallRye Mutiny.  ...  Reactive programming and reactive streams are gaining traction in the Java ecosystem. However, reactive streams implementations tend to be complex to work with and maintain.  ...  The authors would like to thank Georgios Andrianakis, Rodney Russ and Stéphane Épardaud for their constructive feedback.  ...

ThreadLocalMRG32k3a: A statistically sound substitute to pseudorandom number generation in parallel Java applications

Jonathan Passerat-Palmbach, Claude Mazel, David R. C. Hill
2012 2012 International Conference on High Performance Computing & Simulation (HPCS)  
The latest release of the Java Development Kit (JDK 7) tries to tackle this problem with a new class called ThreadLocalRandom.  ...  This point can appear to be very tricky for non-experts, who might be tempted to move this part of the simulation aside.  ...  Acknowledgements The authors would like to thank Florian Guillochon for his careful reading and useful suggestions on the draft.  ...

Changing engines in midstream

Xueyuan Su, Garret Swart, Brian Goetz, Brian Oliver, Paul Sandoz
2014 Proceedings of the VLDB Endowment  
In this paper, we build on Java 8 Stream and add a DistributableStream abstraction that supports federated query execution over an extensible set of distributed compute engines.  ...  With the addition of lambda expressions and the Stream API in Java 8, Java has gained a powerful and expressive query language that operates over in-memory collections of Java objects, making the transformation  ...  There is a rich library of Collector building blocks in Java SE 8 for composing common queries.  ...

A big data file transfer tool for tablet-class machines

Tevaganthan Veluppillai, Brandon Ortiz, Robert E. Hiromoto
2013 2013 IEEE 7th International Conference on Intelligent Data Acquisition and Advanced Computing Systems (IDAACS)  
The motivation for this study is the development of a client/server big data file transport protocol for tablet-class client machines that rely on the Java Remote Method Invocation (RMI) package for distributed  ...  The data transfer protocols include standard Java and C++, and block-data transfers protocols that use both the Java New IO (NIO) and the Zerocopy libraries, and a block-data C++ transfer protocol.  ...  ZEROCOPY Zerocopy is a stream-based file transfer library that differs from Java IO in that it reduces the number of internal data copying and associated context switches.  ...

Stream security particularities in Java

Michał Chromiak, Zdzisław Łojewski
2008 Annales UMCS Informatica  
As an answer to those needs, we discuss the SUN's Java Virtual Machine mechanism provided to assure security to a single object.  ...  Thanks to the mechanism of serialization in Java, it is possible to provide secure solution.  ...  This of course is just a theory, because the results (Figure 3) for the encryption of a stream provide much better byte distribution than the pure stream did, but not to such an extent.  ...
