JuliaHub v6.3.0: JuliaHub v6.3.0 is now available with a number of new features. Release notes are available here and below.

  • v6.3.0 adds the capability to build a sysimage to go along with your job run. The sysimage is built before the job starts. After the sysimage build completes the sysimage is mounted to every Julia process the job utilizes (main and workers). JuliaHub users can choose to create a SYSIMG by checking the "Build SYSIMG" checkbox during job submission. More information on "What a SYSIMG is?" can be found in following link: https://julialang.github.io/PackageCompiler.jl/dev/sysimages.html#sysimages
  • We now have simple caching based on the pre-built SYSIMG's, this feature ensures that additional runs of a job with the same manifest will reuse the already built sysimage.
  • We're excited to introduce a fresh and modern user interface for JuliaHub. This update brings a host of usability improvements and a cleaner design, making user interactions smoother and ensures faster loading. UI improvements includes a major overhaul to Notifications, Registrator and Projects features.
  • We have added a new grouping for shared datasets for easy distinction, using these groupings; end-users can easily distinguish between shared datasets based on who shared them; without going into details.
  • Users can now create folders or directories in File explorer UI, this will help users to organize there files in an efficient way
  • We now have a new search filter for dependencies & dependents in the packages UI, using this feature, end-users can now search for direct and indirect dependencies & dependents for a particular package.
  • You can now remove a project viewer's access by setting the resource's general access level to "No Access"


  • Job time limits can now be made optional by an admin on enterprise installs, if this option is enabled, end-users on the JuliaHub instance can start jobs with no time limits.


  • Julia version has been updated to v1.9.2 in Julia IDE and batch jobs
  • We have added following R packages to WindowsWorkstation app:- ggplot, ggPMX, xpose, xpose4 and vpc
  • End-users can now access JuliaHub Datasets through RStudio app
  • R package "units" is now part of the RStudio app
  • End-Users can now install TinyTex packages in RStudio server and all the newly installed TinyTex packages will automatically go to persistent storage, hence, these packages can be loaded across the sessions without installing them again.

JuliaSim v0.30.0: JuliaSim v0.30.0 is now available with new capabilities and features. Release notes are available here and below. If interested in running JuliaSim on juliahub.com or locally, please do contact us.

  • Improvements in performance, stability and correctness of Collocation Methods
  • Overall stability in the API for generic use cases

Julia for Differential Equations Using Graphics Processing Units (GPUs): Automated Translation and Accelerated Solving of Differential Equations on Multiple GPU Platforms is a new paper co-authored by JuliaHub’s Yingbo Ma (Modeling & Numerics Team Lead), Tim Besard (Software Engineer), Alan Edelman (Co-Founder and Chief Scientist) and Chris Rackauckas (VP Modeling & Simulation). Click here for more.

Julia for Solving Inverse Problems: A Tutorial on the Bayesian Statistical Approach to Inverse Problems is a new paper from 3 Oregon State researchers using Turing.jl’s No-U-Turn Sampler (NUTS), a Markov Chain Monte Carlo (MCMC) algorithm to solve inverse problems.

Julia for Fish: A Bayesian Inverse Approach to Identify and Quantify Organisms from Fisheries Acoustic Data is a new paper in the ICES Journal of Marine Science. Researchers from the National Oceanic and Atmospheric Administration (NOAA) Alaska Fisheries Science Center and the University of Washington Applied Physics Lab use sonar with ProbabilisticEchoInversion.jl to identify and count fish. According to co-author Sam Urmy: “This work was inspired by Celeste.jl, and would not be possible without Julia's automatic differentiation capabilities and the Turing.jl ecosystem.”

Julia for Epidemics and Spin Dynamics: Matrix Product Belief Propagation for Reweighted Stochastic Dynamics Over Graphs is a new paper in the Proceedings of the Natural Academy of Sciences using Julia for two applications: “inference of infection probabilities from sparse observations within the SIRS epidemic model and the computation of both typical observables and large deviations of several kinetic Ising models.” Click here for the paper and source code.

Julia for Net-Zero Hydrogen Production: A Cost Comparison of Various Hourly-Reliable and Net-Zero Hydrogen Production Pathways in the United States is a new paper in Nature Communications. The authors “build a model that enables direct comparison of the cost of producing net-zero, hourly-reliable hydrogen from various pathways … For the United States (California, Texas, and New York), model results indicate next-decade hybrid electricity-based solutions are lower cost ($2.02-$2.88/kg) than fossil-based pathways with natural gas leakage greater than 4% ($2.73-$5.94/kg). These results also apply to regions outside of the U.S. with a similar climate and electric grid.” Furthermore, the authors “use the Gurobi Linear Optimizer in the Julia mathematical programming tool (JuMP) to size system components such that we minimize the LCOH from electricity-based pathways.”

Why Jahan.ai Uses Julia: Why We Use Julia in Our AI Startup is a new blog post from Jahan.ai, an AI startup. According to Jahan.ai, “Handling enormous data for retail giants, including forecasts for over 20 million series in near real-time, demands a robust, efficient, and cost-effective language. Julia fits this bill perfectly with its minimal latency and high-performance capabilities. It allows us to scale effortlessly, processing vast datasets quickly thanks to efficient memory usage and parallel processing. This speed is crucial in an industry where trends shift rapidly. Julia's just-in-time (JIT) compilation and performance, rivaling that of C, enables us to update forecasts multiple times a day. Its unique blend of speed and interpretability, without sacrificing power, helps our clients to react proactively to the ever-changing market demands.”
