That's pretty cool! That probably means that applications will have an easier time. Looks like it has 512-bit SIMD.

I wonder what BLAS they are using, and if the contributions are open sourced.

(SVE isn't 512-bit SIMD like AVX512.) I don't know what BLAS they're using, though I know they've long worked on their own, but BLIS has gained SVE support recently, for what it's worth.

SVE is whatever width the chip designer wants, Fujitsu's implementation is 512-bit according to AnandTech

I know, but it's different apart from coming in different hardware widths, as ARM techies will gush.

Yes, SVE, like the RISC-V vector extension, is a "real" vector ISA, with things like vector length register (no need for a scalar loop epilog), scatter/gather memory ops for sparse matrix work, mask registers for if-conversion, looser alignment requirements (no/less need for loop prologues).

That being said, apart from becoming wider, AVX-NNN has also gotten more "real" vector features with every generation. The difference might not be as huge anymore.
