RELION
RELION (for REgularised Likelihood OptimisationN) is a program that employs an empirical Bayesian
approach to refinement of (multiple) 3D reconstructions or 2D class averages in electron cryo-microscopy
(cryo-EM). Figure 11 shows the performance of RELION on CPU and P100-PCIe. Note that y-axis is in
logarithmic scale. It demonstrates that 1 P100 is 8.8x faster than dual CPU. From the figure we also notice
that it does not scale well starting from 4 P100 GPUs. Because of the long execution time, we did not
perform the profiling for this application. But it is possible that the reason of the weak scaling is similar to
LAMMPS, HOOMD-blue and Amber.
