Effective Parallelization Strategies for Scalable , High Performance Radio Frequency Ray Tracing

We present StingRay, an interactive environment for combined RF simulation and visualization based on ray tracing. StingRay is explicitly designed to support scalable, high performance simulation and visualization of RF energy propagation in complex urban environments using modern, highly parallel computer architectures. We explore three strategies for exploiting parallelism in StingRay and provide evaluations of their scalability and performance on a modern workstation-class system. Results show that a more scalable, higher performing version of StingRay is possible with careful attention to the expression of task-level parallelism in OpenMP.
