    Abstract:

    Earth System Modeling is both compute and data intensive. HPC Systems for Earth System Modeling consist of Compute- and Data-Servers as well as additional servers for visualization and other purposes, that are linked together to provide an efficient, easy to use workflow environment Huge amounts of data are exchanged between the Data-Server and its clients. Coupling the different servers of an HPC System via Shared File Systems is an effective solution for the data transfer problem, which has been successfully implemented at DKRZ. All Data and Scalar Compute Services are IA64, Linux-based computer systems which use the Shared File System for data exchange. Lessons learnt from this implementation will be reported.
