The Teton HPC cluster is the successor to Mount Moran. Teton contains several new compute nodes. All Mount Moran nodes have been reprovisioned within the Teton HPC Cluster. The system is available by SSH using hostname teton.arcc.uwyo.edu or teton.uwyo.edu. We ask that everybody who uses ARCC resources cite the resources accordingly. See Citing Teton. Newcomers to research computing should also consider reading the Research Computing Quick Reference.

Overview

...

Teton is an Intel x86_64 cluster connected via a Mellanox FDR/EDR InfiniBand and has a 1.3 PB IBM Spectrum Scale global parallel filesystem available to all nodes. The system requires UWYO two-factor authentication (2FA) for login via SSH. The default shell is BASH with Lmod modules system is leveraged for dynamic user environments to help switch software stacks rapidly and easily. The Slurm workload manager is employed to schedule jobs, provide submission limits, and implement fair share as well as provide the Quality of Service (QoS) levels for research groups who have invested in the cluster.

Teton has a Digital Object Identifier (DOI) (https://doi.org/10.15786/M2FY47) and we request that all use of Teton appropriately acknowledges the system. Please see Citing Teton for more information.

Global Filesystems

...

The Teton global parallel filesystem configured with a 160 TB SSD tier for active data and 1.2 PB HDD capacity tier for less-used data. The system policy engine moves data automatically between pools (disks and tiers). The system will automatically migrate data to HDD when the SSD tier reaches 70% used capacity. Teton has several spaces that are available for users to access described in the table below.

...

Purge Policy - File spaces within the Teton cluster filesystem may be subject to a purge policy. The policy has not yet been defined. However, ARCC reserves the right to purge data in this area after 30 to 90 days of no access or from creation time. Before performing an actual purge event, the owner of the file(s) will be notified by email several times for files that are subject to being purged.

Storage Increases on Teton

• Project PIs can purchase additional scratch and/or project space at a cost of $100 / TB / year.

• Additionally, PIs can request allocation increases at no cost for scratch and/or project space by submitting proposals that must be renewed when substantial cluster or storage changes occur:

  • the scientific gain and insights that will be or have been obtained by using the system,

  • how data is organized and accessed in efforts to maximize performance and usage.

  • Projects are limited to 1 no-cost increase.

• To request more information, please contact ARCC.

Special Filesystems

Certain filesystems exist on different nodes of the cluster where specialized requirements exist. The table below summarizes these specialized filesystems.

...

The Bighorn filesystems will be provided for a limited amount of time in order for researchers to move data to either the petaLibrary, Teton storage or to some other storage media. The actual date that these mounts will be removed is still TBD.

Project and Account Requests

...

For research projects, UWYO faculty members (Principal Investigators) can request a Project be created on Teton. PIs can then add access to the project for UWYO students, faculty and external collaborators. User Accounts on Teton require a valid UWYO e-mail address and a UWYO-Affiliated PI sponsor. UWYO faculty members can sponsor their own accounts, while students, post-doctoral researchers, or research associates must use their PI as their sponsor. Non-UWYO external collaborators must be sponsored by a current UWYO faculty member.
