Using the Compute Interface with Xpress

The Xpress Optimizer libraries can be configured to out-source optimization computation to a remote Insight Server that supports the Compute Interface.

The Xpress software applications which depend on the Optimizer library for optimization computation (Optimizer Console, BCL, Mosel, Xpress Workbench) therefore inherit the ability to transparently send jobs to Insight.

Some features such as callbacks, multi-start, and the solution enumerator have restrictions applied. For more, see the Xpress Solver online help.

When a solve is started, the optimizer directs any operations that can be solved remotely to the remote server.

To integrate an Insight Compute Server with Xpress you must complete two tasks:
  1. Configure your environment variables.
  2. Configure the user account credentials.
Covered Topics
  • Environment Configuration
    Integration with the Compute Interface must be explicitly enabled, and the URL identifying the location of your Xpress Insight 5 Server must be set before Xpress will create and send jobs. You can also enable additional configuration by settings the path to a configuration file.
  • Providing the REST API Credentials
    For security reasons, the Xpress software does not accept the credentials to the Insight Server via command line or environmental variable.
  • Using the Optimizer to Solve a Problem remotely
    This section provides an overview of submitting a job using the Xpress Optimizer Console from the Command Window prompt.
