c# - microsoft.bcl.simd 发生了什么？

Question

我清楚地记得 C# 的 SSE 增强向量的发布，我知道我们不久前才对它们进行了一些测试。现在，它们似乎从互联网上消失了。 2014 年的 NuGet 包仍然存在，但已除名:

The owner has unlisted this package. This could mean that the package is deprecated or shouldn't be used anymore.

一些引用它们的旧新闻文章仍然可用，但没有新内容。

这个项目是正式终止还是合并到其他项目中？

Answer 1

它们是 System.Numerics 中 .NET 4.6 的一部分命名空间。

来自 Numerics in the .NET Framework - SIMD-enabled vector types (强调我的):

The SimD-enabled vector types are implemented in IL, which allows them to be used on non-SimD-enabled hardware and JIT compilers. To take advantage of SIMD instructions, your 64-bit apps must be compiled by the new 64-bit JIT Compiler for managed code, which is included with the .NET Framework 4.6; it adds SIMD support when targeting x64 processors.

SIMD can also be downloaded as a NuGet package. The NuGET package also includes a generic Vector structure that allows you to create a vector of any primitive numeric type. (The primitive numeric types include all numeric types in the System namespace except for Decimal.) In addition, the Vector structure provides a library of convenience methods that you can call when working with vectors.
