WebJul 29, 2016 · The intrinsics supported by NVIDIA GPUs are not limited to warp shuffle and ballot. Other supported operations include 32-bit and 16-bit floating-point atomics. Regular DirectX 11/12 only supports 32-bit integer … WebJul 26, 2024 · This sample visualizes how wave intrinsics work. Wave intrinsics are a new set of intrinsics for use in HLSL shader model 6. They enable operations across lanes in the SIMD processor cores, helping the performance of certain algorithms such as culling and packing sparse data sets.

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 24, 2024 · Stream compaction can be scalarized with wave intrinsics so that 64x less amount of atomic operations are performed. The idea here is that we will have a per-wavefront bitmask containing set bits for all lanes that wanted to append. This is retrieved by WaveActiveBallot (IsLightCulledInCurrentThread ()).
