Hello Team,
Thank you for the support. I got that working. It was driver issue related to CUDA. Its fixed now. Regards,
Ankit

Maximum number of CUDA devices: 4
This is not the number of available devices, but the maximum number
of devices that StarPU will use, which you can configure with
--enable-maxcudadev=
As Nathalie said, please post the output of starpu_machine_display. If
that does not show up any CUDA device, your CUDA installation seems
bogus somewhere. Perhaps you have several versions of CUDA installed on
your machine, and you need to direct StarPU to some of them, etc. Did
you check that a basic does report your CUDA devices? Something as
simple as this for instance:
int cnt;
cudaGetDeviceCount(&cnt);
if even that fails, you need to check your CUDA installation again,
comparing how you build the above cuda program, and how starpu detects
the CUDA installation (please post your config.log file).
