How many processors should we use to solve Problem X?

How many processors should we use to solve Problem X?

Parallel computation puts many CPUs to work on solving a problem much more quickly than one CPU alone. But this only works if the tasks are carefully scheduled and the additional CPUs are not waiting around for something to do. How do we choose the right number of processors for a given problem ?

Developing Underworld using Python Virtual Environments

Developing Underworld using Python Virtual Environments

The Underworld Community has been supporting usage of Docker containers for developing and running Underworld powered scientific models. They provide a good option to control the running environment (dependencies). Docker container can be used for developing the code base but creating a suitable development workflow has proven challenging so far

Underworld 2.11 Scaling

Underworld 2.11 Scaling

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

How to install Underworld on Mac OSX (Apple Silicon M1)

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.

Scaling in Underworld

Scaling in Underworld

To test scalability we run weak scaling tests on various HPC machines to check the numerical framework remains robust when pushing for higher fidelity models.

How to build Conda packages?

How to build Conda packages?

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

Getting started with Pull requests

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
