> Key: MESOS-3765

> Project: Mesos
> Issue Type: Improvement
> Components: allocation

> The built-in allocator performs "coarse-grained" allocation, meaning that it always allocates the entire remaining agent resources to a single framework. This may heavily impact allocation fairness in some cases, for example in presence of numerous greedy frameworks and a small number of powerful agents.
> A possible solution would be to allow operators explicitly specify granularity via allocator flags. While this can be tricky for non-standard resources, it's pretty straightforward for {{cpus}} and {{mem}}.
