Efficient Radiation Transport Algorithms Using GPU Technology
Agency / Branch:
DOD / MDA
Visidyne, Incorporated, proposes to complete development of the Efficient Radiation Transport Testbed (ERTT), which combines the strengths of state-of-the-art programmable graphical processing units (GPUs) with standard correlated-k (CK) and line-by-line (LBL) methods for computing atmospheric radiation transport. During Phase I, Visidyne showed that overall performance enhancements (decreased computation time) approaching two orders of magnitude are possible with GPU technology. Visidyne also proposes to develop an ERT API library suitable for incorporation into other atmospheric radiation transport codes, such as SAMM2, and to collaborate with Spectral Sciences Incorporated on incorporating the ERT API into SAMM2. Finally, Visidyne proposes to investigate additional strategies for leveraging the power of GPUs beyond those developed in Phase I, concentrating on new functionality available in recently-released and emerging GPU hardware, and in particular on the application of GPU technology to real-time atmospheric-background scene generation.
