What is an HPC Linux administrator?

HPC (High Performance Computing) Linux administrators are IT professionals who manage, configure, and maintain Linux-based HPC clusters and supercomputers. Their responsibilities include installing and updating software, monitoring system performance, troubleshooting issues, and ensuring that computational resources are efficiently allocated to users. They play a critical role in supporting researchers, scientists, and engineers who rely on high-speed computing for complex simulations and data analysis. A strong understanding of Linux, networking, parallel computing, and scripting is essential for this role.

What are the key skills and qualifications needed to thrive as an HPC Linux administrator, and why are they important?

To thrive as an HPC Linux Administrator, you need expertise in Linux system administration, networking, and high-performance computing (HPC) architectures, typically supported by a degree in computer science or a related field. Familiarity with cluster management tools (like Slurm or PBS), scripting languages (such as Bash or Python), and monitoring systems is essential, along with certifications like RHCE being advantageous. Strong problem-solving abilities, attention to detail, and effective communication skills help in troubleshooting complex issues and collaborating with diverse technical teams. These skills are crucial for ensuring the reliability, scalability, and optimal performance of HPC environments in research or enterprise settings.

What are some common challenges faced by HPC Linux administrators, and how can they be addressed?

HPC Linux administrators often encounter challenges such as managing complex cluster environments, troubleshooting performance issues, and ensuring system security while supporting a diverse user base. Staying updated with the latest Linux distributions, scripting automation for repetitive tasks, and implementing robust monitoring tools can help address these challenges. Additionally, effective communication with researchers and end-users is crucial for promptly resolving technical issues and optimizing the computing environment.

What is the difference between Hpc Linux vs Hpc System Administrator?

AspectHpc LinuxHpc System Administrator
Primary FocusManaging Linux-based high-performance computing environmentsOverseeing entire HPC systems, including hardware, software, and network
Required SkillsLinux OS, scripting, cluster management, troubleshootingHardware knowledge, system configuration, user support, security
Work EnvironmentResearch labs, universities, tech companies with HPC needsData centers, research institutions, enterprise IT departments

Hpc Linux specialists focus on configuring and maintaining Linux-based HPC clusters, while Hpc System Administrators manage the broader HPC infrastructure, including hardware and network components. Both roles require Linux skills, but the System Administrator has a wider scope of responsibilities.

Job description

Requisition Id 16496
Overview:
The Field Intelligence Operations Division invites candidates to apply to join our National Security Computing team to contribute to the design, implementation, and management of High-Performance Computing (HPC) systems within a classified environment. We are looking for candidates with experience in HPC architecture, cluster management, and parallel computing, with a proven ability to work within highly secure and regulated environments. This role involves close collaboration with security teams, scientists, and IT leadership to ensure that the HPC infrastructure meets the stringent performance, security, and compliance requirements necessary for classified work.
As part of our team, you will be joining a vibrant group of professionals eager to provide premier customer service to ensure people and information technology remain secure. The team is collaborative and strives to ensure security practices and procedures are understood, implemented, and enforced. All team members deliver ORNL's mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service.
This evergreen posting represents multiple openings for roles across ORNL's high-performance computing classified ecosystem.
Major Duties and Responsibilities:
  • Provide technical leadership in the design, integration, and administration of large-scale Linux-based HPC clusters, high-speed networks, and storage systems.
  • Lead medium to large technical projects, coordinating requirements, schedules, and deliverables across internal and external stakeholders.
  • Architect and deploy advanced infrastructure solutions supporting exascale-class and mission-critical computing environments.
  • Serve as a technical mentor for HPC engineers, guiding best practices in automation, performance tuning, and system security.
  • Develop, implement, and maintain configuration management and automation frameworks (e.g., Ansible, Puppet, Salt) to enhance reliability and reproducibility.
  • Perform advanced system performance analysis, troubleshooting, and optimization, ensuring system scalability and long-term sustainability.
  • Manage critical vendor and partner relationships, representing ORNL's technical requirements during procurement, integration, and system acceptance.
  • Contribute to strategic planning and technology roadmaps, influencing unit goals and technical direction.
  • Collaborate closely with scientists, researchers, and IT specialists to align infrastructure capabilities with research and security objectives.
  • Ensure compliance with DOE cybersecurity standards, configuration baselines, and operational policies.
  • Author technical documentation, present internal briefings, and communicate complex issues and resolutions to management and stakeholders.
  • Participate in on-call rotations, maintenance windows, and incident response as needed to support 24x7 operations.

Basic Qualifications:
  • BS degree in computer science, engineering, or a related technical field.
  • A minimum of 8 years of relevant experience in Linux systems administration or HPC systems engineering.

Preferred Qualifications:
  • Demonstrated experience leading the design and deployment of HPC or large-scale distributed computing systems.
  • Expertise with batch schedulers (SLURM, PBS, LSF) and parallel file systems (Lustre, GPFS/Spectrum Scale).
  • Proven ability to lead technical projects from concept through implementation, balancing technical depth with project delivery.
  • Strong proficiency in automation and infrastructure-as-code frameworks (Ansible, Puppet, Salt).
  • Advanced scripting or programming skills (Python, Bash, Go) for automation and operational tooling.
  • In-depth understanding of high-speed interconnects (InfiniBand, Slingshot, Ethernet) and storage architectures.
  • Experience managing identity and access management systems, including MFA, SSO, and zero-trust frameworks (PingFederate, RSA SecureID, Entra ID).
