In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Extending EGEE VOs with Desktop Grids and porting applications for the extended infrastructure
University of Barcelona
University of Barcelona
A Grid can be a powerful number crunching machine bringing the power of thousands of processors to an application developer's finger tips. Although current EGEE VO infrastructures offer significant amount of resources to run computation and data intensive applications, some scenarios still overgrow the capabilities of existing EGEE VOs. Unfortunately, the two main types of Grids infrastructures, Service Grids like EGEE and Desktop Grid systems like BOINC and XtremWeb, were not interoperable until recently. The European EDGeS project is currently developing a bi-directional bridge connecting this diverse collection of resources.
There is a strong collaboration between EGEE and EDGeS in order to extend the EGEE infrastructure with volunteer and institutional desktop grids (DG) and to support EGEE users to migrate their applications to the integrated EGEE-DG (EDGeS) infrastructure. The goal of this tutorial is to train the EGEE user community how to extend their VOs with desktop grids, how such an integrated infrastructure works, and how to port and run their applications on this infrastructure. By extending EGEE VOs with DG systems EGEE users can transparently exploit the spare cycles of the interconnected DG systems that can contain very large number of processors.
The tutorial has two main parts:
Part 1 explains the characteristics of DG systems and their interconnection possibilities with EGEE VOs. Special emphasis will be given to the different characteristics of the security mechanisms applied in EGEE and in DG systems and how they can be harmonized. This part gives practical case studies how to connect EGEE VOs with either local DGs (example with a campus DG) or with public DGs. This part also describes the operational characteristics of the already existing EDGeS infrastructure that connects an EGEE VO and several DG systems.
Part 2 shows the methodology, various methods and tools by which existing EGEE applications can be ported to the integrated infrastructure. Programming an application for a Grid is not easy. Current Grid application development efforts very often use ad-hoc approaches only when porting the applications. Developers do not follow any suggested methodology and this may result in poorly documented systems that do not fulfill user expectations. In order to avoid this trap, support application developers and provide guidelines when porting an application to the EDGeS Grid platform, the EDGeS Application Development Methodology (EADM) has been specified. This part of the tutorial introduces the EDGeS Grid platform (EGEE extended with BOINC and XtremWeb Desktop Grids) and the EDGeS Application Development Methodology. So far 17 applications from fields of bio-science, chemistry, physics, engineering, e-market, etc. have been ported to EDGeS. Case studies of tools that make the application development easier and examples for applications that have been ported to EDGeS using the EADM will be presented.
In both parts live demonstrations will be provided in order to help the audience to try the technology and the existing EDGeS infrastructure.
Detailed agenda will be available soon.

Desktop Grids in a Clouded World
In today's world of clouds, we tend to forget, that there is a successfull category of distributed infrastructure that is wideley used in science and industry. These are desktop grids. Both the largest Grids for science and in industry are Desktop Grids. This presentation provides an overview of Desktop Grids and their place in the infrastructure world.
Integrating Desktop Grids and integration with Service Grids such as EGEE
An overview of the results of the EDGeS project about integrating different infarstructures, especially from the view of EGEE users.
Porting applications to the Grid using the EDGeS Application Development Methodology
This part introduces the EDGeS Application Development Methodology. So far about 20 applications from fields of bio-science, chemistry, physics, engineering, e-market, etc. have been ported to EDGeS. Case studies of tools that make the application development easier and examples for applications that have been ported to EDGeS using the EADM are presented.
