The Flux Operating Environment (FOE) supports researchers with grants that require the purchase of computing hardware. FOE allows researchers to place their own hardware within the Flux cluster.
To use FOE, we suggest researchers:
- coordinate with ARC prior to including hardware in a proposal or purchasing hardware;
- purchase hardware that is compatible with the rest of the Flux installation;
- obtain a subscription to FOE for each compute node.
A subscription to FOE provides access to the Flux infrastructure — data center, staff, networking, storage and basic software — except the compute hardware.
FOE is available for:
- Researchers who receive funds from external funding agencies for purchasing equipment.
- Researchers who have workflow and/or infrastructure needs that differ significantly from those that can be met by other Flux services (i.e. Standard-Memory, Larger-Memory or GPU Flux allocations).
The hardware added to FOE is for the exclusive use of the research group that added it and will not be part of the Flux allocation pool.
Budgeting for the Flux Operating Environment
The FOE subscription rate and node purchase charges allow for funding from a range of sources: federally funded research projects; general funds; departmental instructional funds; faculty discretionary and research incentive accounts; cost-sharing funds; and faculty start-up or retention package funds. All FOE purchase and subscription costs are charged to a U-M shortcode; no other payment method (cash, credit cards, etc.) is accepted. The costs are determined by the FOE rate that applies to the purchasing researcher and the number and price of the compute nodes being added. FOE use is billed monthly by ITS. The details of the FOE charges will appear on the normal monthly Statement of Activity.
Hardware purchases for FOE are a one-time expense. If made from federal funds, the timing of the purchase relative to the end of the grant period must be consistent with federal regulations. FOE subscription charges are a recurring expense. If made from federal funds, subscription charges can not be prepaid to extend beyond the end of the grant period.
