  1. New Julia Developments

i. Major New Release of DataFrames.jl v0.11:

DataFrames v0.11 has been released by the Julia community with a number of important updates:

  • ‘NA’ has been replaced with ‘missing’, making it much easier to work with missing data

  • Faster joining and grouping

  • Better display of DataFrames

  • Improved documentation

  • Modeling features are now in StatsModels.jl, whereas data import/export features are now in CSV.jl

  • Many other improvements

Don’t let the version number fool you. This version has been in the works for a long time, and leverages important new features in the Julia compiler. See the release announcement and try it out!

ii. JuliaBox - Commercial Version Now Available for University and Corporate Users with Enhancements and Support:

In response to user demand, Julia Computing has introduced a new and improved JuliaBox experience with increased memory and more support. For pricing and more information about the new commercial version of JuliaBox, please contact us. The free version of JuliaBox remains available for current and new users.

iii. Improved C++ Interoperability Interface:

Cxx.jl and CxxWrap.jl allow users to wrap C++ libraries in Julia. Use Cxx.jl to write the wrapper package in Julia code or CxxWrap.jl to write it entirely in C++ and call from Julia with a single line of Julia code. It is also possible to write and call Julia code from within C++, giving Julia and C++ complete two-way interoperability.

iv. JuliaPro Amazon Machine Image and Docker Image:

JuliaPro, the fastest on-ramp for quants, data scientists and researchers, is now available as an Amazon Machine Image on AWS EC2 (Red Hat Enterprise Linux v7.4 and Ubuntu 16.04) and as a Docker image (Ubuntu 16.04 and Centos 7) for use in containerized environments such as Kubernetes. More information is available here.

  1. Julia Computing at SC17 and Intel HPC Developer Conference

Denver hosted the Intel HPC Developer Conference November 11-12 and SC17 November 12-17. Julia Computing participated in both conferences and presented the Celeste case study, one of the latest and most exciting developments in high performance computing using Julia. Julia Computing’s Ranjan Anantharaman was recognized for providing the Best Tutorial at the Intel HPC Developer Conference.  Julia Computing’s Ranjan Anantharaman (left), winner of the Best Tutorial Award at the Intel HPC Developer Conference 2017

  1. Julia Computing at Analytics Vidhya’s DataHack Summit, Sponsored by Intel

Julia Computing was featured as part of the Intel keynote presentation about the future of high performance computing at Analytics Vidhya’s DataHack Summit in Bangalore, India held November 9-11. Julia Computing’s Rajshekar Behar presented Julia’s work with Celeste, Intel and Intel Skylake architecture.

  1. Julia for Astrodynamics

Helge Eichhorn, Software Engineer at Telespazio VEGA Deutschland, presented Astrodynamics.jl: An Open-Source Framework for Interactive High-Performance Mission Analysis at the Open Source Cubesat Workshop on Nov 23 at the European Space Operations Center (ESOC/ESA) in Darmstadt, Germany. 

  1. Julia in Linux Magazine

Professor Mark Vogelsberger, Theoretical Astrophysicist at MIT, published an article in Linux Magazine in Jan 2016 titled “Getting Parallel: Creating Parallel Applications with the Julia Programming Language.” According to Professor Vogelsberger: “The Julia code is ... more than 100 times faster than the equivalent Python code. Multiple dispatch with function calls gives Julia extremely efficient code that is practically superior to any high-level language. Faster code in Julia can be achieved without any tricks like vectorization or outsourcing to C extensions. By contrast, such tricks are often necessary to speed up Python or R code.”

About Julia and Julia Computing

Julia is the fastest high performance open source computing language for data, analytics, algorithmic trading, machine learning, artificial intelligence, and many other domains. Julia solves the two language problem by combining the ease of use of Python and R with the speed of C++. Julia provides parallel computing capabilities out of the box and unlimited scalability with minimal effort. For example, Julia has run at petascale on 650,000 cores with 1.3 million threads to analyze over 56 terabytes of data using Cori, the world’s sixth-largest supercomputer. With more than 1.2 million downloads and +161% annual growth, Julia is one of the top programming languages developed on GitHub. Julia adoption is growing rapidly in finance, insurance, machine learning, energy, robotics, genomics, aerospace, medicine and many other fields.

Julia Computing was founded in 2015 by all the creators of Julia to develop products and provide professional services to businesses and researchers using Julia. Julia Computing offers the following products:

  • JuliaPro for data science professionals and researchers to install and run Julia with more than one hundred carefully curated popular Julia packages on a laptop or desktop computer.

  • JuliaRun for deploying Julia at scale on dozens, hundreds or thousands of nodes in the public or private cloud, including AWS and Microsoft Azure.

  • JuliaFin for financial modeling, algorithmic trading and risk analysis including Bloomberg and Excel integration, Miletus for designing and executing trading strategies and advanced time-series analytics.

  • JuliaDB for in-database in-memory analytics and advanced time-series analysis.

  • JuliaBox for students or new Julia users to experience Julia in a Jupyter notebook right from a Web browser with no download or installation required.
