Abstract
The main objectives of task AT-10, as part of contract W7701-083373, was to profile the performance of the infrared scene generator (IRSG) module of the KARMA simulation framework, pinpoint bottlenecks, optimize critical portions of code through basic corrective measures, and update the SMART (Suite for Multi-resolution Atmospheric Radiative Transmission) library to the latest version. The work has been carried out from January 2012 to March 2012. The profiling has been limited to a basic scenario using the IRSG and the wideband mode. The code optimizations allowed to double the frame rate for this scenario. Some optimization avenues were investigated and could be realized as a part of another task or contract.
