We are excited to announce that R-Universe has been awarded a Google Season of Docs grant. R-Universe is rOpenSci’s platform for testing, building, distributing, and discovering R packages, led by Jeroen Ooms.
ul a:hover{text-decoration: underline;}Pretty permanent URLs! We have improved the URL schema for the r-universe.dev front-end to make it even easier to find and share a link to an R package, article, API, or other resource. The old URLs will now automatically be redirected to the new locations, so this should be a non-breaking change.
Two new packages! We released two new packages that we are using in r-universe to render package documentation: postdoc and prismjs. The goal of postdoc is very simple: generate beautiful single-page package manuals in HTML format. Postdoc uses our prismjs and katex packages for server-side highlighting and math.
The Underworld Community has been supporting usage of Docker containers for developing and running Underworld powered scientific models.
How does Underworld scale on a HPC? In this post we showcase how Underworld 2.11 scales across two of Australia's premiere HPC systems. Gadi - https://nci.org.au/our-systems/hpc-systems Magnus - https://pawsey.org.au/systems/magnus/ The reference model chosen for this scaling showcase is a extended 3D stokes flow: Analytic Solution SolDB3D . Q1P0 elements were used and a fixed solver iteration count for solving the saddle point problem.
The new generation of Apple Mac comes with the new Apple Silicon (M1) chip which has an Arm architecture (as opposed to the older generation that had i386 Intel processor). This brings all manner of troubles and requirements for the development of codes. Here I detail how to install Underworld on Mac OSX Big Sur 11.5.2 (Apple Silicon) using Python 3.9 Important Note: The following guide uses the CMake branch of Underworld.
First of all - I could have put much more words in the title because we are covering a complete workflow for our TYPO3 documentation (for our customers and their sites). We will see the tools used, how it is organized and finally how it is deployed. Format TYPO3 used to use an OpenOffice-based documentation shipped as *.sxw files ages ago.
To date weak scaling tests have been run on two of the largest computers in Australia: Gadi (NCI) and Magnus (Pawsey). Here we present the results of those tests and discuss: Gadi: Weak scaling - SolDB3D Q1 Gadi: Weak scaling - SolDB3D Q2 Magnus: Weak scaling - SolDB3D Q2 - v2.10 vs v2.9 Underworld's Gadi installation is setup as a
As mentioned, packages can be installed directly from our conda channel. You may however want to build your own package at some point in the future or you may want to fix some of ours by submitting a Pull Request on github (You are more welcome to do so...) The following goes through the steps of building a conda package for Badlands which contains Python and Fortran code. This is relatively advanced but not really difficult.
Version control systems and online-communities such as Github have made contributing to the development of opensource software incredibly easy. That is assuming that people get over their initial fear of sharing their code! In this short blog post I go through how to submit a pull request to one of our repository. Do not fear and join us for some fun!
