‘Why We Created Julia’ Turns Ten Years Old: The Julia community celebrated the 10th anniversary of ‘Why We Created Julia’, the announcement that introduced Julia to the world on February 14, 2012. This celebration includes a new retrospective, ‘Why We Use Julia, Ten Years Later’. One hundred Julia users from fields as diverse as data science, finance, robotics, pharmaceuticals, neuroscience, entomology, quantum physics, astronomy, environmental science and energy each contributed a short paragraph (or more) about how they came to use Julia, why they use Julia to replace Python, C, C++, Fortran, MATLAB, SAS and R, what they have accomplished using Julia and why they continue to love the language.

Highlights include:

• “Come for the speed, stay for the community.” Elliot Saba

• “The code was so clean and nice compared to the horrible Python version! … Julia could easily run 50x faster than almost identical code in Python. From then on I was hooked.” David Sanders

• “I stumbled into Julia while trying to do a crazy data transformation in R that was taking forever. I was instantaneously hooked! The syntax is so easy …” Jose Storopoli

• “I am tremendously grateful to have come across the language, as well as its community and all the wonderful people that have helped me on this journey. It is not an exaggeration to say that much of my career successes I owe to the language.” George Datseris

• “I remember working on an R script that needed to loop through 33 million rows of data, doing a complicated … computation that would take 18 hours to run. Literally during one of these 18 hour runs, I saw the Julia announcement post and was immediately desperate for the kind of simple performance it promised. I read the initial manual over a weekend, rewrote my script the following Monday morning, and it ran in 5 minutes. I thought for sure I had made some kind of early termination mistake, but no, it was really just that fast.” Jacob Quinn

• “Best programming decision I ever made :)” Simon Danisch

• “I would not be surprised if, within the next 10 years, Julia is dubbed ‘the language of science’.” Ranjan Anantharaman

• “Using Julia is one of the best choices I made concerning my numerics and code development.” Ronny Bergmann

• “Without the Julia community it is unlikely I would have completed my PhD (and I certainly wouldn't have my current job).” Frames Catherine White

• “This language is awesome.” Tobias Knopp

• “I was hooked. Almost 3 years later I've found that Julia has been my go-to language for nearly everything. The ease of use, speed and community keep bringing me back for more.” Matt Brzezinkski

• “Julia is the language I was longing for.” Cristóvão Sousa

• “In 2020, I switched my work code to Julia, and have never looked back since.” Jakob Nissen

• “Julia is the perfect language for scientific computing and beyond.” Mark Kittisopikul

• “The performance is awesome and amazing!” Qingyu Qu

Free Webinars from Julia Computing: Register today to participate in a free one hour live Webinar from Julia Computing.

Single Instruction, Multiple Data (SIMD) in Julia: SIMD (Single Instruction, Multiple Data) is when the processor executes the same instruction (like addition) on multiple numbers (data) in one instruction. Recent processor architectures come with the capability of running these SIMD instructions on even larger batches of data, making it quite important to make sure that SIMD is used when possible for best performance. Julia offers many ways to take advantage of SIMD. Sometimes it happens automatically, as an optimization, but it is also possible to manually write SIMD code. This workshop will give an overview of the different ways you can use SIMD in Julia.

Performance Optimization of Graphics Processing Unit (GPU) Applications in Julia: In this webinar, we will focus on how to analyze and improve the performance of Compute Unified Device Architecture (CUDA) GPU applications implemented in Julia. This will include the use of CUDA profiler tools, how to effectively use them with a Julia codebase, as well as Julia-specific optimization guidelines.

Free Julia Computing Webinars Available Online: Nearly 40 free Webinars from Julia Computing are available to watch online, including Accelerating Functional Mock Up (FMU) Models with Jacob Vaverka and End-to-End Machine Learning Workflow Using Julia with Jeremie Bouchard. These Webinars highlight how companies are using JuliaHub. Click here to watch.

Inside Big Data Features Julia Computing CEO and Co-Founder Dr. Viral Shah: Inside Big Data published How Cloud Computing is Helping to Solve 3 Problems on Everyone’s Mind Right Now by Julia Computing CEO and Co-Founder Dr. Viral Shah. Dr. Shah describes how Julia is used in the cloud to help analyze the spread of COVID-19, develop safe pharmaceutical treatments and route school buses.

Using Julia With Intel’s oneAPI: Intel’s oneAPI is an open ecosystem for developing performant cross-architecture applications for CPUs, GPUs, and other accelerators. Open-source implementations of Julia are now available using oneAPI. Robert Cohn is a Senior Principal Engineer at Intel Development Tools Software. He explains: “Beyond C++, Intel and the community are enabling open-source implementations of Python, Julia, and Java for oneAPI. Intel developed oneAPI accelerated, drop-in replacements for the very popular NumPy, pandas, and scikit-learn packages and enabled writing accelerator kernels directly in Python with Numba. You can write accelerator kernels using Julia thanks to Julia Computing, and in Java through the efforts of University of Manchester’s Advanced Processor Technologies group. The languages all sit on top of the Level Zero runtime. Level Zero provides services for loading and executing programs, allocating memory, etc. Looking forward, we are leveraging our experiences with Python, Julia, and Java to provide better language runtime support in Level Zero.” More information is available here.
