Abstract: We develop efficient CPU kernels for multiphase compressible flows and evaluate different optimization strategies. The presented software achieves up to 48% of the peak performance on shared memory architectures, outperforming by 9-14X what is considered to be state-of-the-art. On 48-core CPUs we observe speedups of 40-45X and measure up to 360 GFLOP/s over 840 GFLOP/s of the peak.
