Elektron: Pluggable Scheduling Policies
=======================================
##__Scheduling Policies__
* **First Fit** - *Find the first task in the job queue whose
resource constraints are satisfied by the resources available in
a resource offer. If a match is made between an offer and a task,
the offer is consumed in order to schedule the matching task. Else,
move onto a new mesos resource offer and repeat the process.*
* **Bin-packing** - *For each resource offer received, tasks are matched
from the priority queue keyed by the Watts resource requirement. If a task's
resource requirements are not satisfied by the remaining resources in the
offer, the next task in the queue is evaluated for fitness. This way, tasks
are packed into a resource offer.*
* **Max-Min** - *Pack a resource offer by picking a mixed set of tasks
from the job queue (used as a double-ended queue) that is sorted in
non-decreasing order of tasks' Watts requirement. Max-Min alternates
between picking tasks from the front and back of the queue.*
* **Max-GreedyMins** - *Similar to Max-Min, a double-ended queue,
sorted in non-decreasing order of tasks' Watts requirement, to store
the tasks. Max-GreedyMins aims to pack tasks into an offer by picking
one task from the end of the queue, and as many from the beginning,
until no more task can fit the offer.*
