Hi,

Would it be worthwhile using nova-simd to enhance performance?

I'm not sure how useful this would be, considering it's C++.  I only
took a quick look and it looks like it's just wrapping the standard
vector methods we could call ourselves in C.  I may have missed
something though as it was only a quick look.

Hi,

Thanks for your thoughts, I haven't had a detailed look either, but I
suspect you are right. However, I didn't know there were already
vectorization optimizations in Csound. Can you point me to them?

Cheers,
Andrés

Oh, I wasn't talking about vector optimizations in Csound, just what
is in gcc, i.e.:

The compiler will automatically vectorize certain things, especially
calculations in loops. If the calculations in the loop can be arranged
into simple arithmetic, then the loop can be unrolled (put 4
iterations into a block, the block becomes a vector on which the
arithmetic can be done in parallel by the vector instructions).

Regards,
Mike
