At DUG, we offer high-performance computing as a service (HPCaaS) for a wide variety of clients. Built on many years of experience in geophysics, our world-class compute cluster is tailor-made for scientific computing and attracts a diverse range of computationally-intensive projects.
We’re looking for an HPC Expert with experience in on-boarding clients, helping them to build and tune complex packages for performance on DUG’s worldwide HPC infrastructure.
As HPC Expert, you’ll be part of a team of technical experts responsible for ensuring that customers can use our compute infrastructure as productively as possible. Your pragmatic approach will help you deal with third-party software that's not always especially easy to build, compile, understand and tune. You’ll become proficient in the languages and techniques used in these projects, as well as an evolving and somewhat-unique HPC environment.
The HPC Expert will work with end users to perform onboarding, installation, porting, optimisation and tuning.
