Member of the Exper. Team Group The UNICOREpro Client Introduction to Client Plugins Ralf Ratering Pallas Gmb. H Hermülheimer Straße 10 50321 Brühl, Germany ralf. ratering@pallas. com http: //www. unicorepro. com
Functionality of the UNICOREpro Client n Job Preparation – File, execution and control tasks – Complex workflows – Editing, copying, saving, etc. n Resource Handling n Job Monitoring n Job Control n Remote File Browsing n Certificate Handling © Pallas Gmb. H. No distribution without authorization.
Plug-In Concept n Add your own functionality to the Client! – Heavily used in research projects all over the world – More than 10 plug-ins already exist n No changes to basic Client Software needed n Plug-Ins are written in Java n Distribution as signed Jar Archives © Pallas Gmb. H. No distribution without authorization.
Deployment and Installation n User gets Plug-in Jar archive from Web-Site, Email, CD-ROM, etc. n Store it in Client‘s search path 1. Lib directory 2. User Defaults Plugin directory n Client checks signature – Is a certificate in the chain a trusted entry in the keystore? – Is the signing certificate a trusted entry in the keystore? © Pallas Gmb.

Task Plugins n Add a new type of task to the Client GUI n New task can be integrated into complex jobs n Application support: CPMD, Fluent, Gaussian, etc. Add task item Settings item Icon Plugin info © Pallas Gmb. H. No distribution without authorization.
Extension Plugins n Add any other functionality n Resource Broker, Interactive Access, etc. JPA toolbar Settings item Extensions menu Virtual site toolbar Plugin info © Pallas Gmb. H. No distribution without authorization.
Supporting an application at a site n Install the application itself n Add entry to the IDB APPLICATION Boltzmann 1. 0 Description „Boltzmann Simulation“ INVOCATION [ /usr/local/boltzmann/bin/linux. Exec. bin ] END © Pallas Gmb. H. No distribution without authorization.
