Marc Wiedemann


Since 2011, Dipl. Phys. Marc Wiedemann has been working on I/O analysis and optimization. He writes his thesis about cross-layer analysis and optimzation of input/output of high performance computing systems“. Currently, he is focussing on system-wide time and energy monitoring of parallel programs on application, middleware and kernel level. Mr. Wiedemann has reviewed papers for international conferences and took part in paper and poster sessions of the International Supercomputing Conference (ISC) from 2012 to 2015. Currently, he contributes to simultaneous faster, energy conserving runs of parallel I/O workflows in science.
