Byteslice
ByteSlice is a byte-level columnar layout that fully leverages SIMD data-parallelism. Micro-benchmark experiments show that ByteSlice achieves a data scan speed at less than 0.5 processor cycle per column value --- a new limit of main memory data scan, without sacrificing lookup performance. WebOct 18, 2024 · Alignment: Each thin and fat pointer must be usize -aligned. It's possible to define fat pointers with greater alignment requirements. The object pointed to by a thin or fat pointer must be aligned to the most stringent alighment requirement of any of its consituent elements. Note that objects may be declared with alignment requirements greater ...
