[ANNOUNCE] Apache Mahout 0.14.0 Release
The Apache Mahout PMC is pleased to announce the release of Mahout 0.14.0.
Mahout's goal is to create an environment for quickly creating
machine-learning applications that scale and run on the highest-performance
parallel computation engines available. Mahout comprises an interactive
environment and library that support generalized scalable linear algebra
and include many modern machine-learning algorithms. This release ships
some major changes from 0.13.0, most in support of simplicity and tidiness.
To get started with Apache Mahout 0.14.0, download the release artifacts
and signatures from http://www.apache.org/dist/mahout/0.14.0.
Many thanks to the contributors and committers who were part of this
release.
RELEASE HIGHLIGHTS
The theme of the 0.14.0 release is a major refactor for simplicity of usage
and maintenance. Non-core items have been moved to the new “community”
module, and a new “experimental” area has been created for cutting-edge
work that may require user tuning for specific hardware configurations.
STATS
A total of 15 separate JIRA issues are addressed in this release [1].
GETTING STARTED
Download the release artifacts and signatures at
https://mahout.apache.org/general/downloads.html. The examples directory
contains several working examples of the core functionality available in
Mahout. These can be run via scripts in the examples/bin directory. Most
examples do not need a Hadoop cluster in order to run.
FUTURE PLANS
0.14.1
As the project moves towards a 0.14.1 release, we are working on the
following:
* Further Native Integration for increased speedups
* JCuda backing for In-core Matrices and CUDA solvers
* Enumeration across multiple GPUs per JVM instance on a given instance
* GPU/OpenMP Acceleration for linear solvers
* Further integration with other libraries such as MLLib and SparkML
* Incorporate more statistical operations
* Runtime probing and optimization of available hardware for caching of
correct/most optimal solver
CONTRIBUTING
If you are interested in contributing, please see our How to Contribute [2]
page or contact us via email at d...@mahout.apache.org.
CREDITS
As with every release, we wish to thank all of the users and contributors
to Mahout. Please see the JIRA Release Notes [1] for individual credits.
Big thanks to Trevor Grant for a large effort on the refactoring and
cleanup in this release.
KNOWN ISSUES:
* The classify-wikipedia.sh example has an outdated link to the data files.
A workaround is to change the download section of the script to: `curl
https://dumps.wikimedia.org/enwiki/latest/enwiki-latest-pages-articles10.xml-p002336425p003046511.bz2
-o ${WORK_DIR}/wikixml/enwiki-latest-pages-articles.xml.bz2`
* Currently GPU acceleration for supported operations is limited to a
single JVM instance
* Occasional segfault with certain GPU models and computations
* On older GPUs some tests fail when building ViennaCL due to card
limitations
* Currently automatic probing of a system’s hardware happens at each
supported operation, adding some overhead
* Currently the example in the main README errors out due to a packaging
error; we will be fixing this in the next point release

4 Apache Events in 2019: DC Roadshow soon; next up Chicago, Las Vegas, and Berlin!
Dear Apache Enthusiast, (You’re receiving this because you are subscribed to one or more user mailing lists for an Apache Software Foundation project.) TL;DR: * Apache Roadshow DC is in 3 weeks. Register now at https://apachecon.com/usroadshowdc19/ * Registration for Apache Roadshow Chicago is open. http://apachecon.com/chiroadshow19 * The CFP for ApacheCon North America is now open. https://apachecon.com/acna19 * Save the date: ApacheCon Europe will be held in Berlin, October 22nd through 24th. https://apachecon.com/aceu19 Registration is open for two Apache Roadshows; these are smaller events with a more focused program and regional community engagement: Our Roadshow event in Washington DC takes place in under three weeks, on March 25th. We’ll be hosting a day-long event at the Fairfax campus of George Mason University. The roadshow is a full day of technical talks (two tracks) and an open source job fair featuring AWS, Bloomberg, dito, GridGain, Linode, and Security University. More details about the program, the job fair, and to register, visit https://apachecon.com/usroadshowdc19/ Apache Roadshow Chicago will be held May 13-14th at a number of venues in Chicago’s Logan Square neighborhood. This event will feature sessions in AdTech, FinTech and Insurance, startups, “Made in Chicago”, Project Shark Tank (innovations from the Apache Incubator), community diversity, and more. It’s a great way to learn about various Apache projects “at work” while playing at a brewery, a beercade, and a neighborhood bar. Sign up today at https://www.apachecon.com/chiroadshow19/ We’re delighted to announce that the Call for Presentations (CFP) is now open for ApacheCon North America in Las Vegas, September 9-13th! As the official conference series of the ASF, ApacheCon North America will feature over a dozen Apache project summits, including Cassandra, Cloudstack, Tomcat, Traffic Control, and more. We’re looking for talks in a wide variety of categories -- anything related to ASF projects and the Apache development process. The CFP closes at midnight on May 26th. In addition, the ASF will be celebrating its 20th Anniversary during the event. For more details and to submit a proposal for the CFP, visit https://apachecon.com/acna19/ . Registration will be opening soon. Be sure to mark your calendars for ApacheCon Europe, which will be held in Berlin, October 22-24th at the KulturBrauerei, a landmark of Berlin's industrial history. In addition to innovative content from our projects, we are collaborating with the Open Source Design community (https://opensourcedesign.net/) to offer a track on design this year. The CFP and registration will open soon at https://apachecon.com/aceu19/ . Sponsorship opportunities are available for all events, with details listed on each event’s site at http://apachecon.com/. We look forward to seeing you! Rich, for the ApacheCon Planners @apachecon
