Accelerating reactive-flow simulations using vectorized chemistry integration
Nicholas J. Curtis, Kyle E. Niemeyer, Chih-Jen Sung
The high cost of chemistry integration is a significant computational bottleneck for realistic reactive-flow simulations using operator splitting. Here we present a methodology to…

Using SIMD and SIMT vectorization to evaluate sparse chemical kinetic Jacobian matrices and thermochemical source terms
Nicholas J. Curtis, Kyle E. Niemeyer, Chih-Jen Sung
Accurately predicting key combustion phenomena in reactive-flow simulations, e.g., lean blow-out, extinction/ignition limits and pollutant formation, necessitates the use of detail…
