This seems reasonable to me, let's just make sure CI passes. Thanks! |

Many modern CPUs support AVX512 with 512 bit wide vector instructions. Currently, terra only enables AVX extensions (256 bit) for its
vectortype. This PR enables basic AVX512 features if the host CPU supports it.Advantages
This potentially speeds up computations with the
vectortype by factor of 2 as twice as many instructions can be handled at the same time.Disadvantages
None as the old code path (AVX only) is used if the CPU does not support all required AVX512 instruction sets.
