Good idea to use SPECIES_512?

[Viswanathan, Sandhya]

Hi Stefan,

We don’t recommend using SPECIES_512 on non-avx 512 platforms.
If the vector length exceeds the vector size supported by the platform, we don't generate the underlying SIMD instructions.

Best Regards,
Sandhya

Just a quick question. Do you recommend using SPECIES_512 even on non
AVX-512 CPUs? It will make some algorithms a lot simpler, but is it the fastest way?

Greetings,
Stefan
