[http://gridwizardenterprise.org/ Grid Wizard Enterprise] provides powerful tools for harnessing the computing power and making tedious computations feasible. You can follow the instructions on the GWE web site, or the following steps to get running with GWE very quickly.

These steps worked with GWE 0.7.3 on SPL '''linux''' machines

1. Download the installation package from [http://www.gridwizardenterprise.org/maven/org/gwe/client/0.7.3.alpha/gwe-0.7.3.alpha-client.zip here], and put it on your local machine where you are not restricted in disk space

2. Edit your .cshrc/.bashrc to set the environment variables that GWE requires, following by ''source ~/.chsrc''

<pre>
setenv GWE_HOME /path/to/gwe/directory
setenv PATH $GWE_HOME/bin:${PATH}
setenv JAVA_HOME /local/os-exact/bin/java
</pre>

3. edit ''$GWE_HOME/conf/gwe-auth.xml'' to include your login credentials for the resources you are planning to use:

<pre>
<!-- User authentication information -->
<!-- Detailed configuration guide @ http://www.gridwizardenterprise.org/guides/config.html -->
<keystore>
  <accessControl>
     <account user="fedorov" password="?"/>
        <realms>
          <realm schemes="ssh;sftp" domain="*.bwh.harvard.edu" testHost="george.bwh.harvard.edu"/>
        </realms>
     </accessControl>
</keystore>
</pre>

and ''$GWE_HOME/conf/gwe-grid.xml'', to have the correct path to the Slicer installation you are planning to use:

<pre>
<!-- End User Environment & Definitions -->
<!-- Detailed configuration guide @ http://www.gridwizardenterprise.org/guides/config.html -->
<grid>
  <cluster name="LOCALHOST" 
           host="localhost" 
           installRootPath="/projects/birn/fedorov/software" 
           resourceManager="local" 
           queueSize="1" 
           maxWaitMins="0.5" 
           maxHijackMins="120" 
           maxIdleMins="1" >
           <p2elVar name="SLICER_HOME" value="/projects/birn/fedorov/software/Slicer/Slicer3-3.4-2009-05-21-linux-x86_64" />
  </cluster>
</grid>
</pre>

4. launch gwe-web.sh

5. point your browser to [http://localhost:8080 http://localhost:8080]

6. you should see a web interface to GWE, and localhost in the "My Grid" tab. Click on "LOCALHOST", and in the bottom click on the button to install GWE daemon.

7. The daemon should be running, and you should be able to see in with the green "ok" triangle in the list "GWE Daemons"

8. Click on the "LOCALHOST" link to the daemon, and you should be able to submit the following P2EL script that describes a small parameter exploration study for GradientAnisotropicDiffucion filter:

<pre>
${CONDUCT}=$range(0.5,1.5,1) 
${TIME}=$range(0.01,0.05,0.03)
${ITER}=$const(11)
${grad_EXPLORATION_ID}=${CONDUCT}-${TIME}-${ITER} 

${output}=$out(sftp://localhost.bwh.harvard.edu/projects/birn/fedorov/data/Testing/${grad_EXPLORATION_ID}.nrrd)
${input}=$in(sftp://localhost.bwh.harvard.edu/projects/birn/fedorov/data/Testing/MRMeningioma1.nrrd) ${grad}=$const(${grad_SLICER} --conductance ${CONDUCT} --timeStep ${TIME} --iterations ${ITER}) ${grad_SLICER}=$const(${SLICER_HOME}/Slicer3 --launch ${SLICER_HOME}/lib/Slicer3/Plugins/GradientAnisotropicDiffusion) 

${grad} ${input} ${output}
</pre>

At least, this should get you started. Good luck!
