Demonstrations

The following X Window demonstrations require the host where scrun(1) is invoked to be allowed to make connections to the X server where the program output will be viewed. See the Running X Window Applications under SCore chapter for more details.

```
The following window should be displayed:
Under the Multi-User Environment:
To execute the Mandelbrot demonstration program written in MPC++ MTTL under the Multi-User Environment, where scored(8) is assumed to be running on the comp3 host, issue the following command:
```
	$ scrun -nodes=4,scored=comp3.pccluster.org \
	        /opt/score/demo/bin/mandel
```
The same window shown above should appear.
Mandelbrot using MPICH-SCore
Under the Single-User Environment:
To execute the Mandelbrot demonstration using the MPICH-SCore program under the Single-User Environment, login to the server host and issue the following commands:
```
	$ scout -g pcc
	$ mpirun -np 4 /opt/score/demo/bin/pmandel
```
The following window should be displayed:
Under the Multi-User Environment:
