We expect that starting in May, Magellan will be subdivided into smaller resource pools based on the requirements of different cloud testbeds and types of cloud research being done. All MPP users have access to the Magellan cloud nodes via the magellan queue from Carver. To account for cloud usage in NIM, new cloud repositories have been created. They usually have the name c###, where ### is the same as the ### part of your MPP repo name. The exception is if there are mp### and m### repos that share the same number - in this case the project with mp### will have a cloud repo with the name cd###. On May 1 charging will start for Carver. Also on May 1, NERSC will implement "Magellan bank accounts". Cloud repositories act as "Magellan bank accounts". These are not really allocations, but a way to ensure that all projects have fair access to the Magellan resources (when not being used for cloud research). Startup projects will have access to 15,000 MPP hours on Magellan; all other MPP projects will have access to a maximum of 200,000 MPP hours on Magellan. This is a maximum amount a project may use, but there is no commitment to deliver 200,000 hours to any one project. Both Carver and Magellan have a machine charge factor of 1.5.
