Great Lakes

Great Lakes is the university’s flagship open-science, high-throughput, high-performance computing (HPC) cluster. It is designed to support both compute- and data-intensive research. To enable faster access to HPC services, researchers pay only for what they use. It is available to all U-M researchers and replaces Flux.

The Armis2 high-performance computing cluster, in conjunction with Turbo Research Storage, provides a secure, scalable, and distributed computing environment that aligns with HIPAA privacy standards.

Key dates for Armis, the previous service:

  • Armis /scratch directories will be available via Globus through January 27, 2020.
  • Armis /home directories will be available as “read-only” on Armis2 through the end of 2019. Beginning in 2020, the /home directories will be compressed and stored until January 2021.

Armis2 features:

  • Administrative nodes running the Slurm resource manager and job scheduler
  • Linux-based 2 and 4 socket server class hardware in a secure data center
  • High-speed Ethernet (1 Gbps) and InfiniBand (56-100Gbps) network
  • Secure parallel filesystem for temporary data, provided by HIPAA-aligned Turbo Research Storage
