ARCC operates its HPC clusters via an investment model: a UW researcher may invest into compute nodes on the ARCC HPC clusters by funding their purchase. This gives them priority access to those specific nodes, meaning that any jobs running on the investment nodes at the time of request by the investor, will be killed in order to give the investor access. ARCC owns those nodes. Investment buys priority access, not ownership, for the investor. The cost of nodes is based on current market conditions and is shown in this regularly updated page: Node Purchase Estimates .
General (non-investment) cluster usage is free for UW faculty, staff and students within an approved UW research project. If a general-user job lands on an investor’s node, it can be pre-empted (killed) when the investor requests access. Checkpointing the jobs for the purpose of continuing computation on a different node is the responsibility of the users.
Teton Compute Storage (Teton Creek)
Home directory
Each user gets 25G at NO COST.
NO backups.
If a user would like to increase their home directory quota, we charge $100/ TB / year for the storage over 25G.
Gscratch
Each user gets 5T at NO COST (Subject to purge policy).
NO backups.
If a user would like to increase their home directory quota, we charge $100/ TB / year for the storage over 5T.
Project
Each project gets 1T at NO COST.
No Backups, but we do keep 20 days worth of snapshots to help recover from recent accidental data loss.
Users can apply once for a no-cost increase, by providing written justification for the amount of extra storage and its benefit to the UW missions of research, education and economic development.
For any other storage increases in the /project space, we charge $100/ TB / year.
