Research Scientist in High Performance Computing (HPC)

Conducting research for a changing society: This is what drives us at Forschungs­zentrum Jülich. As a member of the Helmholtz Association, we aim to tackle the grand societal challenges of our time and conduct research into the possibilities of a digitized society, a climate-friendly energy system, and a resource-efficient economy. Work together with around 6,800 employees in one of Europe’s biggest research centres and help us to shape change!
TL;DR: Use HPC on largest computers to optimize NLP workloads within the OpenGPT-X project.

No matter whether you create daily COVID-19 forecasts, simulate the largest climate models or tiniest elementary particles – or you build more natural digital conversational partners able to answer the most complex questions: supercomputers are essential for solving the grand scientific challenges of our time.

Jülich Supercomputer Centre (JSC) operates one of the most advanced supercomputing infrastructures for scientific applications in Europe. Amongst them is the JUWELS Booster, currently Europe’s fastest supercomputer utilizing 3,600 NVIDIA A100 GPUs to achieve more than 70 PFLOP/s performance. The “Accelerating Devices Lab” at JSC bundles GPU-related expertise working tightly together with domain scientists and hardware vendors.
