Follow these steps to set up your CEC account so that you can use the Playground software tools. (The first four steps are necessary only the first time you use Playground.)
in your UNIX shell. It will cause the Playground software and course executables to be added to your path every time you create a new shell. The second line will give you access to Playground in the current session.
to get access to the required version of the compiler.
and verify that /home/cec/class/cs333/bin and /pkg/playground/bin are in your path. If they aren't, ask for help.
Your account is now set up to use the Playground software tools. Read the information below for directions on how to start each Playground session and some time-saving recommendations. Then continue with Lab T-1.
Follow these steps each time you begin a session with the Playground distributed programming environment.
to start up the Playground connection manger graphical user interface.
After you start the PGcmgui, an empty window should appear on your screen. It is empty because you have no other Playground modules running.
Once you have started some other Playground modules, you can create a logical connection by drawing an arrow from the presentation entry of one module to the presentation entry of the other module while holding the left mouse button . You create a bidirectional connection the same way, but with the middle mouse button. To delete a connection, click on the connection line with the right mouse button.
Note: Your graphics display is associated with your local machine. If you start PGcmgui on a different machine, you will need to give the other machine permission to put up an X window on your display. For example, suppose your local machine is called foo and you want to run PGcmgui on another machine called bar. Before starting it up, you should type
in a shell on your local machine. Then, in a shell running on bar, you should type
so that the graphics information will go to the correct display.
Another way to create an xterm on a remote machine is to type xrsh followed by the machine name. If you create an xterm this way, it is not necessary to set the display environment variable separately.
