Support for AI and data-driven research
The Longwood high-performance compute (HPC) cluster supports HMS researchers working with AI, machine learning, and data-intensive projects. Hosted at the Massachusetts Green High-Performance Computing Center, it supports both Intel (DGX) and ARM (Grace Hopper) architectures in a secure, flexible computing environment.
The cluster provides scalable GPU power, shared and scratch storage options, containerized tools like Singularity, and job scheduling with Slurm.
Access to the Longwood cluster is available through a secure shell (SSH) at: login.dgx.rc.hms.harvard.edu
Eligibility
Limited to select HMS research projects.The use of the Longwood cluster is restricted due to its limited capacity. It is currently designated for projects funded by the Dean's Innovation Awards (DIA). Eligible researchers will be granted access during their award period.
Security
Supports data up to DSL4 with network-based access control.The Longwood cluster is approved to handle data up to Level 4 data. To improve security:
- Access is restricted to HMS network environments
- Connections must be made via SSH
- Access is gated at the network level (so 2FA is not necessary)
Access details
Connect via SSH from the HMS network.Access to the Longwood cluster is available through a secure shell (SSH) at: login.dgx.rc.hms.harvard.edu
Access is limited to devices on the HMS wired LAN, HMS Secure wireless, or the HMS VPN. The sign-in server does not require two-factor authentication, as connections must originate from a trusted HMS network.
Specifications
Includes DGX and Grace Hopper nodes with H100 GPUs.Longwood features 64 NVIDIA H100 GPUs across a heterogeneous architecture. The setup includes:
- 8 NVIDIA DGX nodes, each equipped with 8 GPUs (80GB VRAM per GPU)
- 2 Grace Hopper nodes, each with 1 GPU (~96GB VRAM) and 400GB+ of shared RAM
This design supports demanding AI and HPC workloads with substantial memory and compute performance.
Cost
Free access for DIA awardees during the project period.There is no charge for researchers using the Longwood cluster as part of a Dean's Innovation Awards (DIA) project for their funded award period.
