Resource pools and budgets
Resource pools are the cost center units of Nuvolos. Resource pools are associated with the tree structure of Nuvolos. Organisations and spaces can be completely or partially mapped to Nuvolos via the management view of the Nuvolos resource control centre.
Resource pools hold a budget against which resources mapped to the resource pool account their usage.
Please note that users cannot create resource pools in a self-service manner. Please reach out to us if you would like to originate a new resource pool - we will discuss your use case with you and offer you the most efficient layout based on your needs.
We call associations between resource pools and Nuvolos objects mappings. The following type of objects can be mapped to resource pools:
- Organisations: An entire organisation may be mapped to a resource pool. This means that all resource usage in the organisation will be billed against the corresponding resource pool.
- Spaces: An entire space may be mapped to a resource pool. All usage in the space will be billed against the corresponding resource pool.
- Specific resource(s) in a space: A particular resource or set of resources may be mapped to a resource pool. This means that for example scaled computation may be mapped to a different resource pool in a space than all other resources.
It is not possible to map a specific resource in all organisation objects to a particular resource pool - this can only be done on a space-by space basis.
The following resource types are available for mapping in Nuvolos currently (the list may change with time as our offering evolves):
- File system storage: File system storage currently used by the user.
- Database storage: Database storage in the Nuvolos Scientific Data Warehouse allocated to the user.
- Database computation: Database computation used by querying the Nuvolos Scientific Data Warehouse.
- HPC interactive computation: Any usage generated by using the interactive high-performance computing feature of Nuvolos.
- Professional services: Professional services carried out by the Nuvolos team, on agreed terms.
- Nuvolos Compute Units: General application runs, which count against the package-based quota specified in the service agreement.
Resource mappings are atomic: it is not possible to split the usage of a particular resource in a space between multiple resource pools. Consequently, it is not possible to:
- Split the file system storage between "normal" and "extra" and only allocate the "extra" to your resource pool.
- Split the interactive high-performance computation costs in a particular space between resource pools depending on the node pool being used.
If you require such fine-grained splitting of resources, we suggest creating multiple spaces.
The role structure of the resource pool builds on top of the Nuvolos role hierarchy while adding an additional administrative role. With respect to resource usage, you may anticipate the following patterns:
- Instance viewers cannot generate and resource consumption. Instance viewers may check the overall budget of their resource pool.
- Instance editors are able to generate resource consumption but they will not induce any change in the resource mappings of a resource pool. Instance editors may check the overall budget of their resource pool.
- Space administrators are able to generate resource consumption but they will not induce any change in the resource mappings of a resource pool. They are additionally able to see detailed usage of their own spaces as well as redacted information about other spaces in the resource pool.
- Organization faculty are able to create new spaces, thus implicitly change (by adding more objects) to the resource pool mapping, however, they may not explicitly re-map resources between resource pools.
- Organization managers are able to create new spaces, thus implicitly change (by adding more objects) to the resource pool mapping, however, they may not explicitly re-map resources between resource pools.
- Resource pool managers are able to check and modify the resource mapping of the resource pool as well as get information about the space administrators of spaces they might be interested in.
New resource pools can only be created by the Nuvolos support. Please reach out to us via intercom to originate a new resource pool.
Users who are space administrators of a space and resource pool managers of a resource pool may map all extra services to resource pools they are managers of. This is particularly useful for researchers who have their own research budget and work in a shared organisation resource pool normally.
This mapping impacts:
- HPC interactive computation - any scaled application runs will be accounted against the selected resource pool.
- Database computation - any query compute time will be accounted against the selected resource pool.
- Database storage - any database storage hold of the space will be accounted against the selected resource pool.
The map does not impact regular provisions, such as NCU capacity for application runs and file system storage hold.
To map a space upon creation to a particular resource pool, if you have resource pool management role in at least one resource pool, you will see a Resource Pool dropdown menu. Select the resource pool you want to map all the extra services in the space to. Following the selection, all extra services will be booked against the selected resource pool. The basic services will still be booked against the organisation's default resource pool.
If you want to change the resource pool mapping of extra services for an existing space, you need to have both space administrator rights and resource pool manager rights in the resource pool you want to map to.
In order to change the space mapping, navigate to Project Configuration from the space overview and select the resource pool in the Resource Pool selection menu item.
Please note that previous resource usage will not be re-mapped by changing the resource pool of a space. In order to reconcile previous usage, please reach out to our support.
Nuvolos supports video library, high-performance computing, and database tables services that can be changed in a self-service manner at three different levels: resource pool level, organisation level, and space level. Resource pool managers can change resource pool level services.
Resource pool level services can only be enabled if the term of the contract allows adding additional services. If your contract does not allow for a specific service but you would like to make use of one, please reach out to support.
To review or change the service settings of your resource pool, go to the reporting dashboard as shown in the video below and change the settings by clicking on the button of the service you wish to enable.
Resource pool level services cannot be disabled in a self-service manner. If you wish to disable a service, please reach out to us.
As resource pools are associated with a list of spaces, organisations and resources, it is possible to create budgets for colleagues that share funding by setting up a resource pool for each budget. This section details some standard use cases for such budgets.
It is possible to create a single resource pool that is being used by multiple organisations. This is useful if:
- The subscriber entity is very large and would like to split its Nuvolos object layout into multiple organisations.
- The subscriber entity is a conglomerate of loosely related sub-units.
It is possible to create personal budgets for your research team members.
- The research team has its own organisation.
- Each member will have their own resource pool, which is mapped to a set of spaces only.
It is possible to create personal budgets for your research team members for only a particular resource type (in practice this is likely to be high-performance computing or data storage).
- The research team has its own organisation.
- Each member has their own space which is generally mapped to the main resource pool.
- The personal resource is mapped to a separate resource pool for each team member.
