Unit V: Advanced gem5 Topics

gem5 supports several other features that may be useful for your simulations; these are covered here.

By the end of this unit, you will be able to:

• Incorporate acceleration and sampling methods into simulations as appropriate.
• Modify and use customized disk images to meet a simulation goal.
• Use multisim to run multiple simulations in parallel.
• Incorporate power models into gem5 simulations.
