Zusammenfassung
In energy meteorology research, scientists from several domains such as physics, meteorology and electrical engineering work together to obtain information needed to characterize energy production from regenerative energy sources such as wind and solar power. For this purpose, several scientific applications were developed to process large data sets from heterogenous data sources in complex and sometimes long-running process chains. In our project WISENT a Grid infrastructure is created to speed up execution of these applications and to ease access to computational and data resources. To achieve this goal, Grid software such as Globus Toolkit and Condor is employed to connect the existing resources of each project partner. But this ongoing process is hindered by blocking firewalls due to strong security policies and by the use of network address translation (NAT). In this paper we describe the current Grid architecture and focus on problems that occurred due to the use of firewalls and NAT. We contribute our present solutions and also discuss alternative solution ideas. One solution using the so-called “hole punching” technology is described in more detail.
