Notes about CDE

  • Licensing:

    Before using CDE, please check that the environment variable for the license: ALTAIR_LICENSE_PATH is set as system environment variable.

    Warning: If ALTAIR_LICENSE_PATH is set as user environment variable only, CDE will fail. For CDE to work properly, ALTAIR_LICENSE_PATH environment variable must be set as system environment variable.

  • User temporary directory %TEMP%:

    (The user temporary directory is by default: C:\Users\<username>\AppData\Local\Temp)

    If there are a lot of files in the user temporary directory (according to our tests, "a lot" means more than 50 000 files, but it could be lower or higher on your computer), then CSS and CDE services will not start. In order to fix this issue, please follow the procedure described below:
    1. Delete unnecessary temporary files, for instance:
      • Using Windows Storage Sense
      • Using another tool (for example: CCleaner,…)
      • Manually…
    2. Restart your computer
    3. Reinstall CSS and CDE:

      Run as administrator the executable file: Active_Distributed_Computation_and_API.bat

      This file is located in the directory: <Installation Directory>\flux\Flux\Bin\prg\win64
