Re: [Starpu-devel] [Inquiry]Starpu Windows Build

[Nathalie Furmento <nathalie.furmento@labri.fr>]

Ahmed,

First, please post your answer to the starpu-devel mailing list. I am not 
always available to read and
answer your email, and other persons on the list may help you as well.

What is happening when you compile your cuda code using nvcc?

starpu_machine_display should at least prints something like:
StarPU has found :
        1 CPU cores
                CPU 0
        0 CUDA devices
        0 OpenCL devices

Try to configure StarPU with the option --enable-verbose, it may help finding 
what the problem is.

Cheers,

Nathalie
