Include AVX512 in listed HardwareIntrinsics #2388
Comments
It should be very easy to implement, we just need someone with the AVX512 hardware to be able to test it. |
Related to this I have been observing some weird issues related to benchmarking on AVX512, see https://mastodon.social/@nietras/110871324242154513 This claims Vector512 being run on net7.0 runtime, and fails running IndexOfAny. Command is something like:
all code can be found in |
Ah I think I get it some of this, this is due to how I set this up perhaps, I use Params for parametizing the parsers to run, this list is then defined for "-f net8.0" then BDN runs each params for each runtime, but what and how it then uses the params for the Vector512 path on net7.0 runtime I do not know. I always struggle with BDN here since parametizing things at runtime is ... not easy. I do not know how IndexOfAny then fails either but presumably this refers to "net8.0 version" of that code on net7.0 runtime then... |
.NET 8 includes support for AVX512.
HardwareIntrinsics.GetFullInfo
should factor that in:https://github.com/dotnet/BenchmarkDotNet/blob/master/src/BenchmarkDotNet/Portability/Cpu/HardwareIntrinsics.cs#L45-L91
