Let's start with vectors of signed integers. A first attempt to write down the function signature could roughly look like this:fn scalar_product(v: Vec<i32>, w: Vec<i32>) -> i32 We take two vectors as input, both containing signed integers (i32), and we return an integer as output...
Consider this simple example: Havingv: Vec<Vec<i32>>I want to addv[1]tov[0]. I'm not even considering sacrificing performance, so cloning any of the vectors is not an option. Thus, no matter how exactly we are going to implement the addition of the vectors, we would need simultaneous...
Suppose I want to parallelise the code below which takes two Rust vectors and sums each element, returning a new vector in the same order as the originals: a = b.iter().zip(c.iter()).map(|(aa, bb)|{aa + bb}).collect(); Using something like this: a = b.par_iter().zip(...
访问vectors[i]时会访问到scalars[2 * i]和scalars[2 * i + 1]组合起来的相同内存区域。 使用union比我们之前的实现方式有一个微妙的优势:union继承有最严格对齐要求的成员的对齐方式。因此Interactions类型会以__m128d进行对齐,并且我们无需像之前那样使用#[repr(align(16))]属性(我使用了#[repr(C)]以确保...
