 The [gem5-resources repository](https://gem5.googlesource.com/public/gem5-resources/) also comes with a number of sample applications that can be used to verify that the model runs correctly.  We recommend users start with [square](https://resources.gem5.org/resources/square), as it is a simple, heavily tested application that should run relatively quickly.

 #### Building gem5 using the image
 See square in [gem5 resources](https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/gpu/square/) for an example of how to build gem5 in the docker.  Note: these directions assume you are pulling the latest image automatically.
