The benchmark was run on a single KNL7210 processor (256 cores) set to quadrant mode and using the MCDRAM as cache. XDS was compiled with the -xMIC-AVX512 option of ifort. This gives | |||

when run with MAXIMUM_NUMBER_OF_JOBS=16 and MAXIMUM_NUMBER_OF_PROCESSORS=16. These parameters, as well as the KNL setup could still be optimized. | |||
