[Starpu-devel] CPU data on a GPU kernel

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

Hello,

Is there a way to do a reduction on a variable hosted on a CPU on a CUDA 
kernel ?

I'm offloading a part of my GETRF on CPU (moving data myself in the CUDA 
kernel) and I have a counter incremented in that part of the kernel.
So the counter is always incremented on CPU with both CPU/CUDA kernel.
This is why I would like it to be always on CPU but I still want StarPU to do 
the reduction...

Is it possible in StarPU ?
Am I understandable ?

Have a nice day,

XL.
