Generally looks reasonable to me. Why is this better than at compile time? |

In an HPC setting for example, it makes it easier to generate one binary that we can use on all nodes without loss of performance. In general, I'm planning to implement some of the BLAS API (as in #207), and the industry standard is to bundle a number of kernels and do runtime dispatch. |

This way we support all architectures that Rust supports, but we dispatch to a SIMD specialization depending on which instruction sets are available at runtime. This is possible thanks to the
target_feature(enable = "...")attribute. I will extend the SIMD capabilities in #207.
