Explicit SIMD can be used to improve Hexe's performance either in throughput or latency depending where it's used.

Architectural Components

Designing Position and State to use the cross-platform types found in std::simd. This would allow for batch position processing. This would also be a very cache-friendly approach.

Individual Components

There are numerous individual areas where parallelism with explicit SIMD can improve performance:

Hexe Main

  • ???

Hexe Core

  • Piece::contained_in
  • PieceMap
    • is_empty
    • len
    • count_of
  • piece::map::{Iter, IterMut}::len
  • piece::map::{Iter, IterMut}::next
