How to handle this situation

sunxiaotianmg commented 1 year ago

float instead of all double type ?

sunxiaotianmg commented 1 year ago

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

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