Secure Computing Environments


The Armis2 high-performance computing (HPC) environment is composed of task-managing administrative nodes and standard Linux-based two- and four-socket server class hardware in a secure data center, connected by both a high-speed ethernet (1 Gbps) and InfiniBand network (40/100Gbps), and a secure parallel file system for temporary data, provided by HIPAA-aligned Turbo Research Storage. The two-socket nodes have up to 24 cores and 156 GB of memory.  There are also 12 V100 GPUs currently on the cluster, but others can be moved on request.

If you are a new user of Armis2, you will need to create an account by submitting an application form (UMICH [Level-1] password required). On the form, please specify the PH-based need for an Armis2 account (e.g., access to a specific dataset through the Precision Health Analytics Platform). Please allow one business day for your application to be processed. If you already have an Armis2 account available, you will need to send an email to specifying the Precision Health–based need to use your Armis2 account as well as the Slurm account owner.

Precision Health also has a private set of six nodes on Armis2. Each node has eight (48 total) RTX2080Ti GPUs and large volumes of fast local storage, and can see all data and software provided on Armis2. These nodes are optimized for machine learning/AI, computer vision, molecular dynamics, and any other GPU-accelerated workload. Precision Health–affiliated researchers who have interest in using the condo nodes should contact


The Yottabyte Research Cloud (YBRC) is a private cloud environment that provides high-performance, secure, and flexible computing environments enabling the analysis of sensitive datasets restricted by federal privacy laws, proprietary access agreements, or confidentiality requirements. The system is built on Yottabyte’s composable, software-defined infrastructure platform and represents U-M’s first use of software-defined infrastructure for research, allowing on-the-fly personalized configuration of any-scale computing resources. This platform allows the creation of any combination of network, CPU, RAM, and storage components into resource groups that can be used to build multi-tenant, multi-site infrastructure as a service.
