Franck Cappello is an expert in HPC with more than 20 years of experience. He initiated the SZ lossy compressor software at ANL. The SZ compressor is one of the most effective existing lossy compressors for scientific datasets. SZ can be used to compress scientific data from simulations and instruments. SZ is integrated into the main I/O libraries (HDF5, netCDF, ADIOS). Franck is involved in several projects of the Exascale Computing Project. He leads the EZ software technology project on lossy compression. He leads the data reduction topic of the CODAR co-design project. He co-leads the data analytics topic of the "Computing the Sky at Extreme Scale" application project where he focuses particularly on lossy compression of N-body datasets. He contributed to several Exascale road-mapping efforts (IESP and EESI). Franck is fellow of the IEEE and recipient of the 2018 IEEE TCPP Outstanding Service Award. He is associate editor of IEEE Transactions on Parallel and Distributed Systems.
