Some of those features seem wild to me, aren't ldiv,exp,log2, isless and fastmath stuff basically just "map to what Intel have given us"? I'm amazed how low level these functions are.
- adgjlsfhk1 5y agothe Intel processor intrinsics are almost all completely broken. there are relatively good libm implementations, but packaging them is a nightmare, as is ensuring good performance across architectures. also in my experience, the Julia versions tend to have better performance.
- eigenspace 5y agoWe often can do better than what Intel gives us, so we do. It takes a lot of time, but slowly lots of low level functions that are taken to be intrinsics by most languages are getting written in pure, high performance julia.
