To: Whom it may concern I have been using this simulator for some processor related educational projects. I noticed a drastically slower performance in simulation as compared to the real thing. To my knowledge, there are no parallelization features included in the simulator as mentioned in this issue https://github.com/cirosantilli2/gem5-issues/issues/15  . I am writing to enquire are there any such features that I am not aware of or are there any plans to include parallelization features into future versions. Hope to hear from you soon.
