[Starpu-devel] StarPU 1.2.0 not working with CUDA 8 and Ubuntu

[Gabriel Gazolla <gabrielgazolla@gmail.com>]

Hello StarPU Team,

I am having problems on making work StarPU 1.2.0 and CUDA 8 on Ubuntu 14.04 or 16.04.

I had to rollback to Ubuntu 14.04 and CUDA 7.5, using StarPU 1.2.0, and it works completely fine.

I used the same procedures for both installation.

I believe it is some incompatibility with CUDA 8.

I would love to hear back from you, if you have any suggestions or if i have to wait for a next release.

Best Regards,

Joao

Here are some suggestions and clues for StarPU developers investigate:

- During compilation of StarPU 1.2.0 I received many warnings from CUDA 8: "nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, and may be removed in..."
