The Ray shell

The Ray shell is responsible for managing all the services that are running on a given node, like the local scheduler, the Plasma store and the Python workers. There is one shell per node.

You can start the shell using

./mojo_shell --enable-multiprocess
             --external-connection-address=/home/ubuntu/shell
             ray_node_app.mojo

This starts ray_node_app.mojo, which starts the object store and listens on the socket /home/ubuntu/shell to establish connections to Python and C++ clients.
