      abstract     = {The paper describes a parallel-I/O extension of the
                      Universal Access Layer, a multi-language interface used for
                      exchange of standardized data objects between Integrated
                      Tokamak Modeling (ITM) codes. Although our evaluation
                      focuses on Lustre, the general idea also applies to other
                      parallel file systems. A snapshot of the current
                      implementation is given, followed by an analysis of user and
                      system requirements. The design derived from the serial
                      version of the UAL is described, and emphasized features
                      such as the ability to choose between serial and parallel
                      I/O are explained. Performance tests comparing the
                      implementation to other I/O methods are made to analyze the
                      impact of the implementation. The outcome shows that the new
                      implementation not only enables the I/O of datasets with
                      several GB in size but also speeds up the write rate by a
                      factor of 13 in the best case.},
