Brand new just-in-time (JIT) compiler for.NET Significant application startup improvement

Learn more about RyuJIT Download RyuJITHelp us make RyuJIT better RyuJIT CTP1: The next-generation JIT compiler for.NET RyuJIT CTP2: Getting Ready for Prime-time

Support SSE2, AVX and other vector instructions in.NET. For AVX, an app can scale up 8X on a processor supporting AVX. For SSE2, an app can scale up 4X on a processor supporting SSE. Developer preview available as part of RyuJIT CTP3.

public struct Vector where T : struct { public Vector(T value); public Vector(T[] values); public Vector(T[] values, int index); public static int Length { get; } public T this[int index] { get; } // With SIMD, these element wise operations are done in parallel: public static Vector operator +(Vector left, Vector right); public static Vector operator *(Vector left, Vector right); //... } Length is fixed, but hardware dependent

float[] values = GetValues(); float increment = GetIncrement(); float[] result = new float[values.Length] // Perform addition as manual loop: for (int i = 0; i < values.Length; i++) { values[i] += increment; } Vector values = GetValues(); Vector increment = GetIncrement(); // Perform addition as vector operation: Vector result = values + increment; Unvectorized code adds one value at a time. Using Vector you can add multiple values simultaneously.
