threads, fibers and GPU kernels

[Suliman via Digitalmars-d]

Modern GPU have thousands of GPU kernels, it's far from CPU 
kernels, but it's interesting for me is there any chance that in 
future they be used in same maner as CPU kernels?

If yes is there any reasons of exit for fibers? Or it would be 
easier to map one thread to one kernel? On system with 1k 
kernels/cores I do not see any reason for fibers for exiten.

Also here was few topics about D3. But what about about you are 
thinging about threading model? I think in next 10 yers even CPU 
would have 32-64 cores.
