Do you mean threads? Not really, they are more like SIMD lanes
that together are more analogous to a CPU thread. See John
Colvin's 2015/2016 DConf talks.
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.
Fibres are for I/O bound problems related to the overheads of
task switching. They offer no benefits (unless you want stateful
generators) for compute bound problems.
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.
