  We present a computational model for the construction of Feldman-Cousins (FC)
corrections frequently used in High Energy Physics (HEP) analysis. The program
contains a grid-based minimization and is written in C++. Our algorithms
exploit vectorization through Eigen3, yielding a single-core speed-up of 350
compared to the original implementation, and achieve MPI data parallelism by
using DIY. We demonstrate the application to scale very well at High
Performance Computing (HPC) sites. We use HDF5 in conjunction with HighFive to
write results of the calculation to file.
