What you do at AMD changes everything 

At AMD, we push the boundaries of what is possible.  We believe in changing the world for the better by driving innovation in high-performance computing, graphics, and visualization technologies – building blocks for gaming, immersive platforms, and the data center. 

Developing great technology takes more than talent: it takes amazing people who understand collaboration, respect, and who will go the “extra mile” to achieve unthinkable results.  It takes people who have the passion and desire to disrupt the status quo, push boundaries, deliver innovation, and change the world.   If you have this type of passion, we invite you to take a look at the opportunities available to come join our team.


Job Description
You will be working on one of the worlds largest and newest HPC systems, at one of the most distinguished global HPC Centres. This system has been designed around AMDs latest EPYC processor, Rome, and will launch later this year; as such, it would currently earn a place in the top 20 systems in the world according to top500.org. This is a significant HPC facility and we are seeking two HPC Applications experts with considerable knowledge in leveraging optimum application performance on large systems.

The HPC Applications Expert role is focused upon initially porting and then subsequently optimizing key HLRS codes. You will already have gained considerable experience working with some of the largest HPC community codes and are familiar with the challenges these codes take in porting and optimizing for a new HPC system. Your optimisation skills will also include a good understanding of compiler and math library optimisation; and there will also be the need to investigate code sensitivities subject to memory latency and cache hierarchy, develop strategies for extreme scaling, and to work with our partner HPE on future memory architectures and Gen-Z networks.

You will also have experience working with well known ISV codes such as LS-DYNA, Star CCM+, Powerflow, Gaussian, Ansys CFX, and Molpro for example.

Based onsite at HLRS, you will be a member of AMDs HPC Centre of Excellence. This will provide the opportunity to interface to other teams within AMD and engage with teams working at a deeper level within the processor and with our compiler and math library teams. As such these roles provides a significant opportunity for an individual to grow their depth of HPC knowledge down to chip level by working for one of the most exciting semiconductor companies currently in the HPC sector.


Role of the HPC Applications Expert

  • Porting and optimizing both source codes and ISV applications to the new HLRS system.
  • Seeking maximum performance through a combination of compilation flags, libraries, and understanding the AMD Rome architecture down to the Floating Point Unit
  • Testing different compilers and math libraries in the pursuit of maximum performance
  • Scaling codes within a single server and then across very large systems
  • Understanding how code performance is affected at the system-level: memory, cache, network, storage etc.
  • Interface with HPC-related groups within AMD: e.g. compilers, libraries, engineering
  • Document and publish performance results and procedures you have generated
  • Automate repeatable procedures such as code compilation, running jobs, etc.
  • Provide feedback to AMDs compiler and math libraries development teams to improve performance
  • Collaborate with HPE on future GenZ HPC investigations and performance testing


Job Requirements
This position requires an individual with excellent verbal and written communication skills (English language) and a good balance of hardware, system architecture and software expertise. The successful candidate must demonstrate the ability to independently manage multiple priorities to deliver results on time, and to build excellent working relationships with both HPE and HLRS

  • Expertise in compiling large codes from source, with appropriately linked math libraries and flag optimisation: VASP, CP2K, NAMD for example
  • Experience with large CFD and Structural ISV codes
  • Appreciation of the different math Libraries for HPC
  • Impact of system level hardware and configuration on performance, such as Infiniband and shared parallel filesystems
  • Solid understanding of configuring baseline synthetic codes e.g. HPL, STREAM, DGEMM, HPCG, HPCC
  • Application expertise across any of CFD, Molecular Dynamics, Quantum Chromodynamics, Structural Mechanics, Climate Change, and weather
  • Hands-on experience with performance profiling and monitoring tools and software performance optimization
  • Bachelor’s degree in a technical discipline (computer science, electrical engineering preferred, physics, applied mathematics)
  • At least 5 years experience working with High Performance Computing applications
  • Good command of the English language 


Preferred Candidate should have

  • Any experience with assembly
  • Experience with large ISV codes including: LS-DYNA, Star CCM+, Fluent, ABAQUS, NASTRAN, Paraview, CFX, Gaussian
  • Knowledge in hybrid MPI+OMP
  • Understanding of memory and cache hierarchy and methods to query performance/latency at each level
  • Understanding HPC dataflow down to the register-level 
  • Experience making performance projections


Additional Expectations

  • Role is based onsite at HLRS in Stuttgart but there will be requirements to travel to other HPC Centres and relevant conferences within Europe, and possibly further afield
  • 2-3 trips a year to Austin, Texas.
  • Possible travel to global HPC conferences (ISC, SC for example)
  • Possibly some travel to India to work with our compiler and library teams
