WebOct 31, 2012 · There are only a few extensions to C required to “port” a C code to CUDA C: the __global__ declaration specifier for device kernel functions; the execution configuration used when launching a kernel; and the built-in device variables blockDim, blockIdx, and threadIdx used to identify and differentiate GPU threads that execute the … Web3 Answers. The header files define an interface: they specify how the functions in the source file are defined. They are used so that a compiler can check if the usage of a function is correct as the function signature (return value and parameters) is present in the header file. For this task the actual implementation of the function is not ...
