ClinWulf | Research Computing & Informatics

ClinWulf is where RCI's clusters handle protected health information. It's for IRB-approved studies in Health Sciences and Medicine, and keeps notebooks, R sessions and viewers on ClinWulf's own nodes and storage.

30compute nodes

24GPUs, including 8 NVIDIA A100

11high-memory nodes, 750 to 1,000 GB

1.5 PBVAST storage

Working with PHI. Use only the data your IRB protocol approves and keep it in your study's folders on ClinWulf. Moving PHI to a laptop or another system must follow your protocol and any data use agreement. Don't take PHI to SeaWulf or NVwulf.
