94 * Plain Coulomb runs through the RF kernels, except with CUDA.
95 * invsqrt is counted as 6 flops: 1 for _mm_rsqt_ps + 5 for iteration.
96 * The flops are equal for plain-C, x86 SIMD and CUDA, except for:
97 * - plain-C kernel uses one flop more for Coulomb-only (F) than listed
98 * - x86 SIMD LJ geom-comb.rule kernels (fastest) use 2 more flops
99 * - x86 SIMD LJ LB-comb.rule kernels (fast) use 3 (8 for F+E) more flops
100 * - GPU always does exclusions, which requires 2-4 flops, but as invsqrt
101 * is always counted as 6 flops, this roughly compensates.
