Table 2.
Simulation speed (in photon/ms, the higher the faster) of MMCL in six benchmarks (B1 to B4, single grid; B1D and B2D, dual-grid); we also report the voxel-based MCX-CL speed in benchmarks B1D and B2D. The master script to reproduce the above results can be found in the “mmc/examples/mmclbench/” folder of our software.
