Hi, 1) Do you use multiprocessing? If so, which implementation, MPICH or OpenMPI? 2) Do you use HDF5 export? If so, which kind of HDF libraries, MPI-enabled or "serial"? The latter is known to be very slow when used in multiprocessing setup, though they should not alter subpixel averaging. 3) Did the FDTD time-stepping speed drop, too, or is it just the initialization? Did you observe performance drop with other computational tools as well?
