AI/HPC Data cluster system Administrator 

What you will do

System Architecture innovations are key to position imec for success in fast evolving workloads of tomorrow and to differentiate imec’s process technology innovations with system level value propositions. The Compute System Architecture (CSA) group at imec leads research for futuristic compute hw-sw codesign to extend imec’s semiconductor research leadership deep into the next decade.  
The CSA unit is building its own high-performance compute cluster for system research experimentation. We rely on this HPC/AI cluster to drive our research and succeed with consumers all over the world. 
We are seeking an experienced Unix System Administrator who is eager to use and to grow his or her technological skills on a worldwide stage. In this role, the successful individual builds, maintains and manages the HPC/AI cluster, working out solutions to support the research, providing training, and assisting in the development of an overall research IT strategy. From early on, you help empower our breakthrough innovations. You can expect to be given challenging assignments, following-up and researching state-of-the-art cluster management techniques, and taking ownership and responsibility for the HPC/AI cluster. 

Objectives of this Role

  • Linux HPC sysadmin
  • Hardware maintenance of HPC system 
    • Maintain complex setups involving Infiniband, Lustre, and various hardware accelerators in servers and workstations (GPU, FPGA, …).
    • Monitor datacenter health using preexisting management tools and respond to hardware issues as they arise; help build, test, and maintain new systems as needed.
    • Help install and maintain servers and components.
  • Software maintenance of HPC system
    • Installing and maintaining complex and optimized software stacks across a variety of machines.
    • Installing and maintaining scientific software packages through configurable module systems (eg EasyBuild).
    • Installing, maintaining and supporting the creation and running of containers and virtualization systems.
    • Installing and maintaining job scheduling system(s) for varied workloads.
  • Perform server administration tasks, including user/group administration, security permissions, group policies, print services, research event log warnings and errors, and resource monitoring, ensuring system architecture components work together seamlessly.
  • Closely interact with the central ICT management. 
  • Perform routine/scheduled audits of the systems, including all backups.
  • Proactively follow-up and experiment with the newest trends in high-performance computing systems (tools, hardware and software, …) to continuously support and improve the research.
