Administering Execution Workers

Xpress Insight executes scenarios by sending jobs to an execution service running on an execution worker. An Xpress Insight Execution Worker is an instance of the Mosel remote launcher—it accepts jobs from the Xpress Insight server, runs any required scenarios, and returns results. Workers can be mapped to execution services and made available to the Xpress Insight system.

When deployed on the cloud, the Xpress Insight server provides a local execution service with one local execution worker that is suitable for small/medium jobs.

High capacity worker servers can be added as part of a paid contract and deployed for use with Xpress Insight.

The division of concerns among execution services and execution service mappings provides for fine-grained control of the compute resources that can be dedicated to or consumed by executing jobs.

For example:

  • You might create a FAST_LANE execution service for small, high-throughput jobs, and a SLOW_LANE execution service for jobs that will take a long time. This arrangement would prevent the slow jobs from blocking the fast jobs.
  • By creating several execution services, you can divide the compute resources into equal (or unequal) chunks for use by several apps with different requirements.

Model developers specify execution modes through Mosel source code annotations, and these are mapped to execution services via the Execution Services page of the admin interface.

Covered Topics
  • Requeuing Disconnected Jobs
    A disconnected job is one that has terminated unexpectedly. They may occur, for example, if a Mosel process terminates unexpectedly, or because of an infrastructure outage of the network or an execution worker's host.
  • Accessing the Execution Services Page
    Go to Execution Services in the Admin menu to configure Execution Workers.
  • Editing Execution Worker Settings
    An Execution Worker is hosted and provisioned when an instance of the Xpress Insight server is deployed. Additional execution workers can be added by FICO as part of a paid contract.
  • Adding or Editing Execution Services and Mappings
    For information on adding and editing Execution Services and Execution Service Mappings, see the FICO Xpress Insight User and System Administrator Guide.
