问题
I have a question: where should I using OpenCL data types? For what are us? Which are covered they?
回答1:
Some types are defined in the OpenCL C programming language, like int, float4, etc.
The corresponding types are defined in the host API with the cl_ prefix, like cl_int, cl_float4, etc. These types are used in the OpenCL API functions, and should be used to pass kernel arguments and compute the size of buffers for example.
