Under this tab, a third tag bar displays the RAPIs (Resource Allocation Project Identifiers) for the selected allocation year. The tables contain detailed information for each allocation project and the resources used by the projects on all of the clusters. The top of the page summarizes information such as the account name (e.g. def-, rrg- or rpp-*, etc), the project title and ownership, as well as allocation and usage summaries. | Under this tab, a third tag bar displays the RAPIs (Resource Allocation Project Identifiers) for the selected allocation year.

Compute-related resources granted by core-year and GPU-year allocations require research groups to submit what are referred to as | Compute-related resources granted by core-year and GPU-year allocations require research groups to submit what are referred to as <i>jobs</i> to a <i>scheduler</i>. A job is a combination of a computer program (an application) and a list of resources that the application is expected to use. The [[What is a scheduler?|scheduler]] is a program that calculates the priority of each job submitted and provides the needed resources based on the priority of each job and the available resources. | ||
