Introduction

The Mosel remote invocation library (XPRD) makes it possible to build applications requiring the Xpress technology that run from environments where Xpress is not installed—including architectures for which Xpress is not available. Relying on the Mosel Distributed Framework (see Mosel module mmjobs), this self-contained library (i.e. with no dependency on the usual Xpress libraries) provides the necessary routines to start Mosel instances either on the local machine or on remote hosts and control them in a similar way as if they were invoked through the Mosel libraries. In particular, the published functionality includes

• redirection of standard streams (input, output and errors);
• compiling and loading of models;
• running and interrupting models.

In addition to these standard operations, the library supports the file handling mechanisms of mmjobs (transparent file access between instances) as well as its event signaling system (events can be exchanged between the application and running models).
