The getting-started guide presents a series of steps where you can
generate flexpoints by combining Simics and Flexus. The goal for
flexpoints generation is described in much more detail in several papers.
These are listed in the simflex webpage: www.ece.cmu.edu/~simflex
Please, spend some time going through any one of them to get the
high-level picture of SimFlex. Also, slides from tutorials are
available in the same website.
The two scripts you mentioned in your e-mail (create-initial-flexpoint
and create-flexpoints) can only use Trace-based
simulators. These two scripts are NOT performing the actual simulation.
They are just setting up checkpoints and flexpoints of your benchmark. The
actual simulation takes place in the run-job script, where
you are able to choose any available simulator to perform your
experiments.
