Wolfgang FringsHead of Application Optimization Team, Jülich Supercomputing Center
Wolfgang Frings is heading the application optimization team at the Jülich Supercomputing Centre (JSC). He works together with developers and users on porting and optimizing codes, especially focusing on parallel I/O. He is author of several software tools used at many HPC centers. Among these are SIONlib, a library to support task-local parallel I/O on large-scale systems; LLview, a batch-system monitoring software; JuBE, a benchmarking environment; and LinkTest, a highly scalable MPI point-to-point network benchmark used for interconnect verification on various HPC systems. He has contributed to a number of national and European projects including PRACE, where he is involved in the development and management of the technical review process for access to Tier-0 resources. Moreover, he works together with international partners on the integration of LLview components into the Eclipse Parallel Tools Platform with particular focus on their optimization for petascale systems.
