Notably different than the rest of the projects in this portfolio, this page is to showcase my published conference paper that I presented at the International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics in 2021.

Under the supervision of Dr. Matthew Barry at the University of Pittsburgh and in collaboration with NASA's Jet Propulsion Lab, I contributed to a project working to calculate the view factor of thermoelectric generators using ray-tracing. The view factor is a metric for the proportion of radiation shared between two bodies, while ray tracing is the method of tracking the trajectory of a path from an emitter to a receiver.

The calculating program itself had already been established by previous student researchers, but my contribution was that of implementing multi-GPU acceleration. By subdividing the code onto each available GPU of a computer the total computational time could be reduced by a linear factor of how many GPUs were used. The maximum speed-up ratio achieved was 1.89, indicating near-perfect linear speed-up
