System Requirements

• 64-bit architecture (Linux, Windows, OS X)
• GPU Hardware (NVIDIA, AMD, Intel)
• OpenCL (already included by default with most GPU drivers)

Programming Environment

• Scala
• SBT (Scala build tool)
• IntelliJ IDEA (preferred IDE)

Download, Install, and Configure Programming Environment

Note: These instructions are based on the preferred IDE, IntelliJ IDEA.

1. Download and install the lastest 64-bit JDK (JDK8).

2. Download and install the latest IntelliJ IDEA IDE. (The Community Edition works fine.)

3. Download and install the Scala Plugin in IntelliJ. This plugin includes SBT.

   From the Welcome to IntelliJ IDEA window, select Configure, select Install JetBrains Plugins (or Browse Repositories), select Scala, click Install

4. Configure the project SDK in IntelliJ

   From the Welcome to IntelliJ IDEA window, select Configure, select Project Defaults, select Project Structure. If there is <No SDK>, click New to add the JDK that was installed in Step 1.

Now you are ready to clone a CCT repository.

Download CCT-Tutorial and Verify

1. Check out from Version Control.

   • From the Welcome to IntelliJ IDEA window, select Check out from Version Control, select GitHub, enter https://github.com/hpe-cct/cct-tutorial.git" for the Git Repository URL. Enter the Parent Directory. Then click Clone.
   • Click “Yes” to open the build.sbt project file.
   • Check “Use auto-import” and “Create directories..”, make sure the proper “Project “SDK” is selected, then click “OK”.
   • Select both the root and build modules to include. Click “OK”.

2. Verify. A good first example to try is the BackgroundSubtraction application, available here.

   • In your IDE, navigate to the directory cct-tutorial/src/main/scala/tutorial/cogio/.
   • Open BackgroundSubtraction.scala.
   • Right click in the source window and select Run ‘BackgroundSubtraction’.
   • Verify that the application compiles and launches in a debugger window.
   • You can then double click on any field in the left panel, such as “suspicious”.
   • And then click Run.

Now you are ready for the next step, Getting Started. (Note: this is just a place holder link for now)

Common Problems

1. Problem: The BackgroundSubtraction application has an error loading the courtyard.mp4 file.

   Solution: The courtyard.mp4 file in the CCT-Tutorial repository is stored with Git LFS. You will need to download and install this program. More information can be found here: http://git-lfs.github.com.

2. Problem: IntelliJ IDEA does not show any Featured Plugins, Browse JetBrains Plugins, or in Browse Repository.

   Solution: If you are behind a firewall, you will need to configure an HTTP proxy setting in IntelliJ. To find the proxy settings dialog box from the Welcome to IntelliJ IDEA window, select Configure, select Plugins, click Browse repositories…, click HTTP Proxy Settings…. Enter your proxy settings here.

3. Problem: Intellij IDEA doesn’t work with 64-bit JDK in older versions of IntelliJ IDEA.

   Solution: Make sure you launch the 64-bit version of IntelliJ IDEA.

4. Problem: IntelliJ IDEA cannot find the 64-bit JDK VM in older versions of IntelliJ IDEA.

   Solution: Make sure you set the JAVA_HOME and IDEA_JDK_64 environment variables to the 64-bit JDK you have installed.
