Administering Execution Workers and Services
The FICO® Xpress Insight Installation Guide documents how to install execution workers. After they have been installed and correctly licensed, workers can be mapped to execution services and made available to the Xpress Insight system.
A single execution worker, xsrv:localhost/insight, is available with a Community license.
The division of concerns among execution workers, 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.
- 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 of a large server 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.
