15. 2013 Status Better development environment and more development tools Significantly increased and more varied software stack Higher level of support for several widely used programs/codes Several advanced trainings regarding code development Several ongoing projects with a variety of objectives and scopes

16. 2013 (Human eCloud) Not reached critical mass of staff yet! Very limited elasticity for taking on (even small) new projects Application expert support Application expert career path? “Salary evolution” Status Advanced support services

17. Coordinated efforts

19. The Role of Application Experts in the Swedish e-Science Infrastructure Date: October 4, 2011 The Role of Application Experts in the Swedish e-Science Infrastructure Date: October 4, 2011 Time and project prioritization Ultimately, it is the responsibility of the center director to assess what a reasonable time-commitment is for a given project. Is it for example okay for the application expert to allocate three, six, or more months to a given project? If many application experts become available for long-term commitments to code development or other research projects, then a formal procedure for obtaining that type of application expert support may have to be set up. For now, however, we propose that long-term commitments are established, handled, and prioritized by the application expert and the center director of the site where the application expert is employed.

20. Role and purpose of the application expert community The general role of the application expert community should be to provide advanced support to e-Science researchers. However, exactly what constitutes advanced support will likely vary significantly among the various e-Science research fields and communities. Examples of advanced support could include: tuning and optimizing code parallelizing code compiling, installing, and benchmarking code helping with visualization techniques and tools helping with workflow for analysis of simulation output and data management helping with selection of code given a specific scientific question creating tutorials and manuals organizing workshops Role and purpose of the application expert community The general role of the application expert community should be to provide advanced support to e-Science researchers.

21. The national SNIC knowledge base The idea is that basic support for any given scientific application can be handled by adding information to the knowledge base. Hence, application experts should provide information, help, tips-and-tricks, etc. regarding the most widely used computational tools and scientific applications within their field of expertise on the national SNIC knowledge base. There is also a SNIC internal wiki, which should be used to share information with other SNIC personnel regarding how to compile, install, and run a given application. The internal wiki could also be used for documenting the resource requirements for major applications.

22. The national application-support RT queue Application experts should commit to monitor the application-support RT queue and work with cases that fall within their field of expertise. Some cases may be handled by providing some application specific insight that enable “first-line” support or system administrators to solve the case, whereas other cases may require substantial efforts. In the latter case, it is not required that the support case receives highest priority immediately as long as it is communicated to the requestor when time can be allocated to looking at the case. The application-support e-mail address will also serve as one of the points of contact for proposing projects for application experts to work on.
