Targeted computing load of the data center.
Green: A consolidation-based scheduler. Accounts for computing and not network
load when taking task placement decisions.
RoundRobin: Distributes computing tasks among servers equally in a circular
Random: A server for task execution is selected randomly.

Dynamic Voltage and Frequency Scaling (DVFS) power management of servers.
When enabled all idle servers are put in sleep mode to conserve power.

Changes internal scheduling, so it is also important for virtualization. If
turned on, VMs try to extend the time of task execution to exploit
underlying DVFS. If turned off, VMs execute tasks as fast as possible.
When turned on, a single pool of VMs is already deployed before the
simulation starts, and the task are sent to these VMs. If turned off, no VMs
are deployed and tasks are directly sent to servers.
The number of instructions required to be executed by the task.
TargeAmount of memory required to be allocated during the task execution.
Amount of storage that needs to be available during the task execution.
The size of task description in bytes that need to be sent to the server selected
for task execution.
Task execution deadline in seconds.
Amount of bytes sent out of the data center after successful task execution.
