GPU-Accelerated Finite Element Method for Modelling Light Transport in Diffuse Optical Tomography
Figure 3
Effect of single-precision arithmetic on forward solutions. Shown are the differences between single and double precision solutions for logarithmic amplitude (a) and phase (b) of the complex field computed in a cylindrical domain along a line from the source across the cylinder. The solid line shows the solution error for a system matrix assembled in double precision and solved in single precision while the dashed line represents the solution for a system matrix assembled and solved in single precision.
