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 is a

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.

Underworld and Docker (part 2)

By the way, before you read this post, catch up with how we use docker by reading part 1 Docker allows us to distribute pre-built applications which are hosted in a virtual machine and are therefore platform independent. This simplifies things for us (only one platform we need to support)

Underworld and Docker (part 1)

While huge improvements in usability have been achieved in Underworld2, the installation process is still unfortunately as painful as ever. This difficulty is in large part due to Underworld's numerous dependencies, and also the multiple platforms we try to support. Compounding this, the legacy of a individual user's machine often
