Longwood is the newest High-Performance Compute Cluster at HMS. It is located at the Massachusetts Green High Performance Computing Center.
...
This provides a heterogeneous environment with both Intel (DGX) and ARM (Grace Hopper) architectures. Module management is supported through LMOD, allowing easy loading of software suites like the NVIDIA NeMo deep learning toolkit and more.

The cluster is currently only accessible via secure shell (ssh) command line from the HMS network:
Two-factor authentication (DUO) is not required for logins because all connections must originate from an HMS network. Currently, the login server hostname is: login.dgx.rc.hms.harvard.edu |

gpu_dgx - the standard GPU partition
gpu_grace - this targets the special Grace Hopper nodes. You’ll need to be using software compiled for ARM
gpu_dia - the DIA dedicated GPU partition which takes priority over gpu_dgx
cpu - the partition available to run jobs that do not require a GPU card. This partition does not include Grace Hopper nodes.
TimeLimit is up to 5 days for both partitions
