Applying patterns for porting complex workflows onto the Grid
The Grid is becoming a mature infrastructure for running complex scientific applications, not limited to one single domain. Recently, an increasing interest to port applications to the Grid (legacy or not) has emerged in different scientific communities, and several higher level portals and tools have been developed. Unfortunately, very little attention has been given to the manner in which an application should be re-designed or modified to be executed on the Grid. Based on our experience, we propose a set of patterns for porting applications onto the grid, which collect typical problems or design decisions to be done during the “gridification” of applications. We present some results obtained by the application of these patterns to real-word applications that were ported onto the Grid.
