The Planck Process Coordinator Workflow Engine ProC

The vast amount of data produced by satellite missions is a challenge for any data reduction software in terms of complex job submission and data management. The demands on computational power and memory space qualify the satellite data reduction to be prototype of grid applications.

Therefore, the Planck Process Coordinator Workflow Engine ProC for the Planck Surveyor satellite has been chosen as a Grid Use Case within the AstroGrid-D project.

The ProC is interfaced to the Grid Application Toolkit (GAT), which allows the execution of jobs on the submission host, on clusters via the PBS and SGE GAT adapters, and on the Grid, using the Globus Toolkit 2 and 4 GAT adapters for process-to-process communication.
