Re: [Starpu-devel] Error - No worker may execute this task

[ASUDE ASUDE <ajitsdeshpande@gmail.com>]

Hello,
 I have done both actually - 
./configure --enable-opencl --disable-cuda 
and 
set STARPU_NCUDA=0
set STARPU_NOPENCL=2

Still got the error. 
But one thing i notice that in my code STARPU initialization function is called as starpu_init(NULL) , no conf structure there passed

Do you reckon that could be the culprit? How does one a starpu_conf structure to use OpenCL devices?

Thank you.

See part 3.4 of the StarPU Handbook, you need to either disable cuda at
./configure time, or set the STARPU_NCUDA environment variable to 0,
because NVIDIA drivers don't permit both CUDA and OpenCL at the same
time for a given device.
