Project Description
Project Objectives
Plan of Action
Understand physics behind
Convert and compile existing 3dimensional Fortran subroutines
into one comprehensive “C” tool
propagation and interaction
of high-power USPL with
matter
Make computations of smallscale propagation/
interaction problems
efficient and effective
Make computations of largescale propagation/
interaction problems
possible and efficient
Make output of calculations
easily understandable and
visually appealing
Optimize the 3-dimensional tool
to increase speed calculations
and minimize memory space
required.
Implement a parallel version of
the 3-dimensional tool for largecluster GPU computing using MPI
and CUDA
Develop a GUI to realize the
propagation and interaction of the
laser with matter

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.

Deliverables
(Software/Documentation)
• 3D USPL Propagation Code
– Need for reliable computational tools for the analysis of High-Power USPL
propagation in atmosphere
• GUI Program & GUI User Manual
– Visual representation of the laser propagation in both space and time. Most
likely implemented in Matlab.
– Manual documents the process of creating a new animation from output data.
• GPU Cluster Interface
– Any and all software required to interconnect the multiple standalone
computers into one functional cluster for high performance computations.
• GPU Cluster User Manual
– Complete write-up documenting the process of adding new nodes and running
new codes.
