Gpu wave intrinsics
WebSep 3, 2024 · In .NET Core 3.0, we added a new feature called hardware intrinsics. Hardware intrinsics provide access to many of these hardware specific instructions that can’t easily be exposed in a more general-purpose mechanism. They differ from the existing SIMD intrinsics in that they are not general-purpose (the new hardware intrinsics are … WebFeb 19, 2013 · 1. Yes you can use SIMD intrinsics in the kernel code on CPU or GPU provided the compiler supports usage of these intrinsics. Usually the better way to use SIMD will be using the Vector datatypes in the kernels so that the compiler decides to use SIMD based on the availablility, this make the kernel code portable as well.
