| <h2>What is DUCC?</h2> |
| |
| <p> |
| 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. |
| |
| <p> |
| <i style="color:#009900;"> |
| Core UIMA |
| </i> |
| provides a generalized framework for applications that |
| process unstructured information such as human language, |
| but does not provide a scale-out mechanism. |
| <i style="color:#009900;"> |
| UIMA-AS |
| </i> |
| 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. |
| <i style="color:#009900;"> |
| UIMA-DUCC |
| </i> |
| 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. |
| |
| <h2>What is ducc-mon?</h2> |
| |
| <p> |
| <i style="color:#009900;"> |
| ducc-mon |
| </i> |
| stands for Distributed UIMA Cluster Computing Monitor. |
| It comprises a web server that is meant to display information about |
| the running DUCC including: users' Jobs, users' Reservations, users' |
| Services and the DUCC System itself. |
| |
| <h2>What is the DUCC demo?</h2> |
| |
| <p> |
| The |
| <i style="color:#009900;"> |
| demo |
| </i> |
| comprises a DUCC installation within the apache.org domain. |
| A computing cluster has been configured and started, and a continually |
| running driver simulates users? work submissions. |

| Use a browser to visit |
| <a href='http://uima-ducc-vm.apache.org:42133'>http://uima-ducc-vm.apache.org:42133</a> |
| which yields |
| the associated web server home page. The visitor is free to navigate and |
| explore an actual DUCC working system as a view-only user. |
| |
| <p> |
| The purpose of the web server (known as ducc-mon) is to provide information |
| about the running system. It will help to answer questions such as: |
