What You'll Do

The High Performance Computing (HPC) Engineer works with directorates within TTS to support, refine and advance the system administration/management of Tufts High Performance (HPC) compute cluster. The HPC system is critical to researchers and users (faculty, student, staff) at all levels across the university and is maintained with enterprise level expectations. The position will take ownership of projects that include identifying problems, developing testing protocols, and developing and implementing solutions. The work often requires coordination of Tufts researchers, TTS staff, and outside vendors. The role will also assist the larger team within Research Technology to assess and evaluate ongoing innovation and cutting-edge solutions to meet research computing needs. 

HPC Systems Support: 

• Maintain the HPC ecosystem from system spec, provisioning, OS installation, maintenance including login, file transfer nodes, compute nodes, job schedulers (slurm), virtualization layer (vmware) and interface with larger team regarding network, storage administration, data center load balancer and firewall issues.
• Maintain user facing HPC web gateways (Open OnDemand, Jupyter Notebook, Lab, Hub, FastX, OpenXDMod, Starfish, Galaxy, RStudio, etc).
• Install, maintain and test common open source and commercial software stacks for both cpu and gpu computing. AI/ML/DL stacks, Anaconda, PyTorch, TensorFlow, RAPIDS, etc.) and containers such as singularity and docker.
• Utilize configuration management and security best practices to maintain systems with tools such as ansible. Document all work and provide regular progress updates.
• Work closely with storage admin to co-maintain HPC storage, features and subsystems
• Respond to outage, emergency or urgent systems issues.

Operational Improvements: 

• Develop, document, automate continual operational improvements in the HPC system administration service.
• Improve metrics, availability, and resource management of cpu/GPUs.
• Maintain scripts to user, group, systems management.

HPC Systems Innovation and Support: 

• Provide system administration services and assist other team members to evaluate Proof of Concept (POC) systems to foster innovative architectures and solutions in new and emerging paradigms such as composable computing, GPU virtualization, cloud bursting, multi-site federation.

Service Management, Education, Outreach: 

• Work with team members to provide full life cycle system administration service through specification, purchase, installation, maintenance as well as service marketing, community building, outreach, training, education, and support.
• Maintain ties with the larger system administration and research computing community to better understand new management paradigms, methods, and opportunities.
