(Choose 4)  \nA. Reduce the total amount of computation necessary to complete a job.  \nB. Allow short Jobs to complete even when large, long jobs (consuming a lot of resources) arerunning.  \nC. Support the implementation of service-level agreements for multiple cluster users.  \nD. Allow multiple users to share clustersina predictable, policy-guided manner.  \nE.
