Prime calculation example using extension method for array (ClooExtensions.cs). Published to native binary via CoreRT - see tasks.json
.
C#:
// Prepare data - 2,3,4,5,6,7,8,9,10,11,12,13,14,...
int[] Primes = Enumerable.Range(2, 1000000).ToArray();
Primes.OpenCLForEach(IsPrimeKernelFunctionCodeString);
// Expected result - 2,3,0,5,0,7,0,0,0,11,0,13,0,...
Kernel code string contents:
kernel void GetIfPrime(global int* message)
{
int index = get_global_id(0);
int upperl=(int)sqrt((float)message[index]);
for(int i=2;i<=upperl;i++)
{
if(message[index]%i==0)
{
message[index]=0;
return;
}
}
}
Requirements:
- newest
VSCode
with C#/Omnisharp extension OR newestVisual Studio 2017
- .NET Core 3.1 SDK installed ( cmd:
dotnet --info
) - Windows 10 SDK + Visual studio build tools for c++
- GPU driver with OpenCL support
- for linux/macos create
Cloo.dll.config

The project targets .NET Core, but code files should work with .NET 4.7.2 as well (after installing Cloo
nuget package).
