Hi,
I have some code that was not initially written to be used via pyCUDA. However,
it consists of some CUDA kernels of which one is the main kernel that is
depending on/calling the others. Unfortunately, I did not manage to get it to
work, since, with the below situation, I always get the following error:
pycuda._driver.LogicError: cuModuleGetFunction failed: not found
For the line:
main_kernel = mod.get_function('main_kernel')
The code looks something like this. It is simplified here for readability
reasons.
Of course, the code is wrapped into
mod = SourceModule(""" <THE CODE> """, no_extern_c=1)
CODE:
#include "cutil_inline.h"
extern "C"
{
#include <time.h>
}
extern "C"
{
#include <float.h>
}
#include "custom.cuh"
extern "C"
{
void main_kernel(float* inp_P, unsigned int N, float* mappedX, unsigned int
no_dims) {
// … Some code …
}
}
However, custom.cuh is not just a simple header file unfortunately, but rather
the header for custom.cu. To even complicate the whole story more, custom.cuh
includes more_custom.cuh which, in turn, also has more_custom.cu.
When building this without pyCUDA, I would first compile the three .cu
(main_kernel.cu, custom.cu and more_custom.cu) files and then link with the
object file of the .cu file (e.g. Main.cu) that would be calling main_kernel().
Are there any suggestions how to proceed to make this work with pyCUDa?
Thank you in advance.
Best,
Cedric
