 Demo: Apache UIMA DUCC

DUCC stands for Distributed UIMA Cluster Computing. DUCC is a cluster management system providing tooling, management, and scheduling facilities to automate the scale-out of applications written to the UIMA framework.

Core UIMA provides a generalized framework for applications that process unstructured information such as human language, but does not provide a scale-out mechanism. UIMA-AS provides a scale-out mechanism to distribute UIMA pipelines over a cluster of computing resources, but does not provide job or cluster management of the resources. UIMA-DUCC defines a formal job model that closely maps to a standard UIMA pipeline. Around this job model DUCC provides cluster management services to automate the scale-out of UIMA pipelines over computing clusters.

What is ducc-mon?

ducc-mon stands for Distributed UIMA Cluster Computing Monitor. It comprises a web server that is meant to display information about the running DUCC including: user Jobs, user Reservations, user Services and the DUCC System itself.

What is the DUCC demo?

The demo comprises a DUCC installation within the apache.org domain. A computing cluster has been configured and started, and a continually running driver simulates user work submissions.
