Groups and Allocations
The policies guiding the interaction between investments, research groups, and allocation groups are outlined below. In a nutshell:
- A faculty member with a Research Computing investment is known as an investor. The investor may sponsor other users to work with the resources.
- Every user of Research Computing resources must have a sponsor. Every user’s primary group will be that of their sponsor.
- Access to the resources of other investments is granted through secondary membership in an allocation group. Allocation groups have no primary members.
- All groups must have at least one Long-term Storage Unit (LSU) in order to be functional.
A University of Florida faculty member may purchase Research Computing resources, at which point that faculty member becomes an investor.
- All investments have a beginning date and an end date. There are no restrictions on when an investment is allowed to begin.
- It is not uncommon for an investor to have multiple investments spanning different time period.
- Investors may sponsor a group of other users to work with their investment, including students, post-docs, or other collaborators.
Each sponsor has an associated Linux/LDAP group. Sponsored users will be added to the sponsor’s group, which becomes their primary group.
- The name of the sponsor’s group will generally be the last name of the sponsor, or something similar.
For accounting and collaboration purposes, investors may request that additional groups be created under their sponsorship, and that some portion of one or more of their investments be allocated to those groups. Such groups are referred to as allocation groups.
- Allocation groups have no primary members. In other words, a user’s primary group will always be that of his or her sponsor.
- Through secondary membership in an allocation group, users can gain access to any resources that have been designated for that allocation group.
A research collaboration, department, college, center, or institute may invest in Research Computing resources. In such a case, a faculty member will be designated as the investor (and therefore sponsor) of the collaborative allocation group.
- A faculty member must be associated with the investment for contact, management, and accounting purposes.
- Access to collaborative allocation groups is still through secondary group membership. Any user of these resources must still have a faculty sponsor, whose group will serve as the user’s primary group.
In the special case that an investor wants to sponsor a user to be a member of an allocation group, but not the investor’s primary group, a new group will be created in order to record the association of the user with the sponsor. The name of this group will be the same as the sponsor’s associated primary group with a “0” added to the end.
A faculty member’s first investment into Normalized Compute Units (NCUs), no matter the quantity, includes a default allocation of two Long-term Storage Units (LSUs), which is retained until the faculty member ceases investment.
- If the investor is sponsor of one or more allocation groups, the investor may choose which group receives the default LSU allocation.
- Separate LSU investments must be made in order to provide storage for remaining groups.
