Re: [Starpu-devel] GPU issue with r12137

[Xavier Lacoste <xavier.lacoste@inria.fr>]

I applied the patch on top of starpu-1.1 (r12511) and this seems to work.

Thanks,

XL.

I don't see any reason why a commit called "Use different streams for gpu-gpu
transfers" would alter a mono-gpu execution....

Well, actually there is also another change in it: we also make all
threads able to use streams, not only the GPU-driving threads. Could you
try the attached patch, which reverts just that?  I'm afraid that means
diving into a CUDA bug, I don't see what is wrong in us doing that.
