How to handle this situation

Answer 2 · 2023-09-11T06:58:27.000Z

float instead of all double type ?

ILGPU will query the OpenCL driver about supported functionality. In this case, OpenCL has reported that the Intel GPU does not support 64-bit floating point operations.
You will either need to stop using double, or you could potentially use the 32-bit only mode, and ILGPU will convert double to float as necesary (https://ilgpu.net/docs/03-advanced/04-math-functions/)

It seems that the problem can only be solved by using float and Math (MathMode. Fast32BitOnly) together

Answer 5 · 2023-09-13T08:52:30.000Z

float instead of all double type，In this MathMode. Fast32BitOnly, the correct results can be obtained
