A few examples of how Julia is being used today include:
BlackRock, the world’s largest asset manager, is using Julia to power their trademark Aladdin analytics platform.
Aviva, Britain’s second-largest insurer, is using Julia to make Solvency II compliance models run 1,000x faster using just 7% as much code as the legacy program it replaced.
“Solvency II compliant models in Julia are 1,000x faster than Algorithmics, use 93% fewer lines of code and took one-tenth the time to implement.” Tim Thornham, Director of Financial Solutions Modeling
Berkery Noyes is using Julia for mergers and acquisitions analysis.
“Julia is 20 times faster than Python, 100 times faster than R, 93 times faster than Matlab and 1.3 times faster than Fortran. What really excites us is that it’s interesting that you can write high-level, scientific and numerical computing but without having to re-translate that. Usually, if you have something in R or Matlab and you want to make it go faster, you have to re-translate it to C++, or some other faster language; with Julia, you don’t—it sits right on top.” Keith Lubell, CTO
UC Berkeley Autonomous Race Car (BARC) is using Julia for self-driving vehicle navigation.
“Julia has some amazing new features for our research. The port to ARM has made it easy for us to translate our research codes into real world applications.” Francesco Borrelli, Professor of Mechanical Engineering and co-director of the Hyundai Center of Excellence in Integrated Vehicle Safety Systems and Control at UC Berkeley
Federal Aviation Administration (FAA) and MIT Lincoln Labs are using Julia for the Next-Generation Aircraft Collision Avoidance System.
“The previous way of doing things was very costly. Julia is very easy to understand. It’s a very familiar syntax, which helps the reader understand the document with clarity, and it helps the writer develop algorithms that are concise. Julia resolves many of our conflicts, reduces cost during technology transfer, and because Julia is fast, it enables us to run the entire system and allows the specification to be executed directly. We continue to push Julia as a standard for specifications in the avionics industry. Julia is the right answer for us and exceeds all our needs.” Robert Moss, MIT Lincoln Labs
Augmedics is using Julia to give surgeons ‘x-ray vision’ via augmented reality.
“I stumbled upon Julia and gave it a try for a few days. I fell in love with the syntax, which is in so many ways exactly how I wanted it to be. The Julia community is helpful, Juno (the interactive development environment for Julia) is super-helpful. I don’t know how one can write without it. As a result, we are achieving much more and far more efficiently using Julia.” Tsur Herman, Senior Algorithms Developer
Path BioAnalytics is using Julia for personalized medicine.
“We were initially attracted to Julia because of the innovation we saw going on in the community. The computational efficiency and interactivity of the data visualization packages were exactly what we needed in order to process our data quickly and present results in a compelling fashion. Julia is instrumental to the efficient execution of multiple workflows, and with the dynamic development of the language, we expect Julia will continue to be a key part of our business going forward.” Katerina Kucera, Lead Scientist
Voxel8 is using Julia for 3D printing and drone manufacture.
“The expressiveness of a language matters. Being high level and having an ability to iterate quickly makes a major difference in a fast-paced innovative environment like at Voxel8. The speed at which we’ve been able to develop this has been incredible. If we were doing this in a more traditional language like C or C++, we wouldn’t be nearly as far as we are today with the number of developers we have, and we wouldn’t be able to respond nearly as quickly to customer feedback regarding what features they want. There is a large number of packages for Julia that we find useful. Julia is very stable – the core language is stable and fast and most packages are very stable.” Jack Minardi, Co-Founder and Software Lead
Federal Reserve Bank of New York and Nobel Laureate Thomas J. Sargent are using Julia to solve macroeconomic models 10x faster.
“We tested our code and found that the model estimation is about ten times faster with Julia than before, a very large improvement. Our ports (computer lingo for “translations”) of certain algorithms, such as Chris Sims’s gensys (which computes the model solution), also ran about six times faster in Julia than the ... versions we had previously used.” Marco Del Negro, Marc Giannoni, Pearl Li, Erica Moszkowski and Micah Smith, Federal Reserve Bank of New York
“Julia is a great tool. We like Julia. We are very excited about Julia because our models are complicated. It’s easy to write the problem down, but it’s hard to solve it – especially if our model is high dimensional. That’s why we need Julia. Figuring out how to solve these problems requires some creativity. This is a walking advertisement for Julia.” Thomas J. Sargent, Nobel Laureate
Intel, Lawrence Berkeley National Laboratory, UC Berkeley and the National Energy Research Scientific Computing Center are using Julia for parallel supercomputing to increase the speed of astronomical image analysis 225x.
Barts Cancer Institute, Institute of Cancer Research, University College London and Queen Mary University of London are using Julia to model cancer genomes.
“Coming from using Matlab, Julia was pretty easy, and I was surprised by how easy it was to write pretty fast code. Obviously the speed, conciseness and dynamic nature of Julia is a big plus and the initial draw, but there are other perhaps unexpected benefits. For example, I’ve learned a lot about programming through using Julia. Learning Julia has helped me reason about how to write better and faster code. I think this is primarily because Julia is very upfront about why it can be fast and nothing is hidden away or “under the hood”. Also as most of the base language and packages are written in Julia, it’s great to be able to delve into what’s going on without running into a wall of C code, as might be the case in other languages. I think this is a big plus for its use in scientific research too, where we hope that our methods and conclusions are reproducible. Having a language that’s both fast enough to implement potentially sophisticated algorithms at a big scale but also be readable by most people is a great resource. Also, I find the code to be very clean looking, which multiple dispatch helps with a lot, and I like the ability to write in a functional style.” Marc Williams, Barts Cancer Institute, Queen Mary University of London and University College London
