Re: [Starpu-devel] [SimpleHelp] Declaring and Using a Codelet in C++

[Gabriel Gazolla <gabrielgazolla@gmail.com>]

Hello StarPU Team,

Just figured it out how to solve this problem, here is the answer:

===

struct starpu_codelet cl;

starpu_codelet_init(&cl);

cl.where = STARPU_CPU | STARPU_CUDA;

cl.cpu_funcs[0]  = multiply_cpu; //FORGOT [0]

cl.cuda_funcs[0] = multiply_cuda; //FORGOT [0]

cl.nbuffers = 3;

cl.modes[0] = STARPU_R ;

cl.modes[1] = STARPU_R ;

cl.modes[2] = STARPU_RW;

cl.name="hello";

===

You also have to use EXTERN.

===

extern "C" void multiply_cpu (void *buffers[], void *args); //FORGOT EXTERN

extern "C" void multiply_cuda(void *buffers[], void *args); //FORGOT EXTERN

===

Hope this solution to be archived on the forum, so people can use if they have the same problem.

Best,

Joao

Hello StarPU Team,

I am trying to compile (build.sh) my project  , but on the file matrix_spu.cpp I can't make the "struct starpu_codelet cod" to work.

The idea behind it is to later on, create a vector of starpu_codelet s.

I am receiving errors on lines 16 and 17. 

Can you please help me compile this code?

Best Regards,

Joao
