To get the source code for this example, create a directory called
org/openspaces, make it your working directory, and use Subversion:

     svn co http://www.openspaces.org/svn/scn/trunk ./scn

To build the example, cd to org/openspaces/scn and run 'ant build'.
This will create a subdirectory named deploy with the standard OSGi
deployment structure.

To deploy the example, run 'ant deploy'.  This will create the
directories shared-computation-feeder and shared-computation-worker in
the $JSHOMEDIR/deploy directory.

To run the example:

     - Start one GSM
     - Start four GSCs
     - Start gs-ui
     - Deploy shared-computation-worker with two primaries and one
       backup
     - Deploy shared-computation-feeder

By default there are five worker threads running in each processing
unit.  The GSC output window will show some workers calculating
results and others waiting for results (the allowed price values are
quantized to ensure some collisions).
