WAT Distributed Compute Controller Configurations

The distributed compute works through a controller node and compute nodes. The controller node needs to be set up in a slightly different way than the compute nodes. This configuration set defines the controller node configurations.

The Distributed Compute package can be downloaded HERE.  You will want to download Overlay-WAT1.1.7z.

Program Setup

The distributed compute package downloaded only provides supplemental files that are needed for distributed compute. You will still need to set up your Controller and Compute Nodes with HEC-WAT and perform additional steps to set up.

  1. Under your C Drive, create a folder called Programs (if it does not already exist).
  2. Within Programs, unzip your HEC-WAT package.
    Location where HEC-WAT Package should be unzipped

  3. Unzip Overlay-WAT1.1.7z. Copy the contents within (HEC-WAT and DC folders) and paste them in C:\Programs.

  4. Navigate to C:\Programs\HEC-WAT\HEC-WAT and open the following config editors in a text editor
    1. HEC-WAT-controller.config
    2. HEC-WAT.config
  5. Copy the contents from HEC-WAT-controller.config and paste them at the bottom of the HEC-WAT.config file.
  6. Comment out line 77 in the HEC-WAT.config file for the controller node. (vmparam -Djava.rmi.server.hostname=127.0.0.1) 
  7. Save and close the config file. 
  8. To streamline running HEC-WAT, recommend navigating to C:\Programs\HEC-WAT\HEC-WAT and creating desktop shortcuts for HEC-WAT.exe and WatTaskList.exe.
  9. Last, HEC-RAS is not an executable and needs to be installed. HEC-WAT 1.1 uses HEC-RAS 6.5. The setup package can be downloaded from HERE.
