The EELA-2 project is organized into 6 main activities, just like "departments" in a factory. The activity identified by "NA3" is the one in charge of providing technical support to researchers wanting to port their applications on the EELA-2 Grid infrastructure.
Using another metaphor, if we imagine the EELA-2 project as a tree, it would look like the picture below. SA2 (the network layer) as the base. SA1 (the Grid infrastructure itself) as the trunk, supporting the brunches and leaves (which are the applications). On the top of SA1, JRA1 provides additional services/APIs that can be used by the applications. NA1 (the administrative management) takes care of the tree so that it can grow up healthy. Last but not least, NA2 (dissemination) is in charge of attracting new users/consumers to the fruits (the results generated by the applications).

The set of application supported by NA3 is not closed. New applications are welcome to join at any time. The candidate applications will be selected taking into consideration the following criteria:
- Suitability for Grid deployment
- Easiness of gridification
- Grid added value
- Usage of the infrastructure (number of jobs and frequency of runs)
- Number of involved institutions from Europe and Latin America
- Potential outreach / impact (in the scientific community, industry, socially in the country, towards policy / decision makers).
However, only applications proposed by researchers affiliated with one of the EELA-2 partner/member institutions are eligible to be supported.
Organizational structure
Formally, NA3 is organized into 4 sub-activities, named tasks:
