7 DISTRIBUTION STATEMENT XXX– Unclassified, Unlimited Distribution Major Milestones Converted Propagation Code ( December 23, 2011 ) – Previous Fortran subroutines have been converted and coupled into one object oriented C program effectively modeling all Non-Linear Schrodinger terms. GPU Cluster Implementation ( April 15, 2011 ) – Parallel version of the 3D code has been implemented with CUDA to allow for meaningful large scale testing. Numerical Testing and Comparison ( April 30, 2011 ) – Real experimental laser characteristics are input and simulated to compare with that of the experimental results. GUI Development ( May 7, 2011 ) – Output data is compiled and converted into a 3D animation that portrays the laser propagation and interaction with matter.
