DistSim

A VM placement simulator with energy-efficiency focus.

DistSim has the following available strategies:

• A KSP (Knapsack) based strategy
• A EC (Evolutionary Computation) based strategy
• An enery-unaware strategy

Execution:

$ python distsim.py -t TRACEFILE -o OUTDIR -pm #PHYSICAL MACHINES -vma #STARTING VIRTUAL MACHINES -vmo #ENDING VIRTUAL MACHINES -vme #INCREMENT VIRTUAL MACHINES STRATEGIES

Where

• TRACEFILE is the trace file to be used. Traces can be found here: https://github.com/vonpupp/planetlab-workload-traces
• OUTDIR is the output folder where simulation results will be stored
• #PHYSICAL MACHINES is the number of physical machines
• #STARTING VIRTUAL MACHINES is the starting number of virtual machines
• #ENDING VIRTUAL MACHINES is the ending number of virtual machines
• #INCREMENT VIRTUAL MACHINES is the increment of the virtual machines
• STRATEGIES are: -seu (energy-unaware strategy) -sksp (Knapsack based strategy) -sec (Evolutionary Computation based strategy)

The setup scripts can be found in the setup folder.
