Assembly of FETI dual operator using CUDA

Dataset attached to the conference paper titled "Assembly of FETI dual operator using CUDA" submitted to the PDSEC 2025 workshop.All data is in CSV format, semicolon is used as a separator.The parameters_* files contain the measurements for determining the optimal parameter settings. On the left side of the table there are the parameters used, on the right side the timing results. (Factor order is replaced with solve type. L,U=rowmajor, LHH,UHH=colmajor.)The dualop_approaches.csv file contains the timings of all available approaches to assemble and apply the dual operator.set = preparation, update = preprocessinghttps://github.com/It4innovations/espreso
