A single instruction is used to apply the same operation to multiple pieces of data. The prototypical example is addition, where one instruction can do e.g. 4 32-bit additions. A single SIMD addition should be roughly 4 times faster than performing 4 individual additions.

Web20 dec. 2024 · Our 4-bit implementation outperforms HotSpot by a factor of up to 40x, the 8-bit up to 9x, the 16-bit up to 4.8x, and the 32-bit version up to 5.4x. There are several reasons for the speedups obtained with the use of SIMD intrinsics. In the 32-bit case, we see the limitation of SLP to detect and optimize reductions. WebWhen using SIMD, there are several tips that can help ensure efficient use of the technique. First of all, it is important to keep the number of instructions to a minimum. Since SIMD applies the same instruction to multiple data elements in parallel, it is important to keep the number of instructions to a minimum to ensure efficient use of the technique.
