The 2021-22 rates for the Lighthouse Cluster have been approved. These rates represent cost recovery for the Lighthouse Cluster, and do not include any support your unit may choose to provide.
The Lighthouse cluster is meant to support researchers with grants that require the purchase of computing hardware or require hardware configurations not available on Great Lakes. Lighthouse allows researchers to work with ARC to purchase their own hardware and have it within the Lighthouse Slurm environment, with ARC providing the data center, staff, networking, storage and software. More information is available on the Lighthouse webpage. In addition to the hardware purchase cost, there is monthly charge to support the hardware in the Lighthouse environment.
|Lighthouse Service Cost||$743.07/node/year ($61.92/node/month)|
To support research using high performance computing, the College of Literature, Science, and the Arts (LSA) will cost-share the monthly operating charge for researchers paying on LSA unit shortcodes. For fiscal years 2022-23 and 2023-24, LSA will provide a 88% subsidy on the monthly service charge. The table below provides an estimate of Lighthouse Operating Expenses using published ITS rates for FY2021-22. The rates for LSA researchers will change, and the table updated, if ITS rates change. LSA does not anticipate continuing the LSA subsidy for Lighthouse nodes after FY2023 and FY2024 due to the small number of people who use service across U-M and LSA. Please plan accordingly for the change in cost that would occur at the start of FY2025 if you continue to use Lighthouse.
|ITS Rate / Node||LSA Researcher Rate||LSA / College Subsidy|
|Annual||$743.07/node/yr||$89.16 (12%)||$653.90 (88%)|
|Monthly||$61.92/node/month||$6.81 (12%)||$55.11 (88%)|
