AFAIK on GNAT they are OS threads. However, when implementing my own green threads (for a virtual machine) I've found out that assigning twice than the available tasks than CPU cores (or, available hyperthreads if HT is on) for some reason increased performance, so it seems worth experimenting rather than relying on theoretical assumptions.
Anyway, on my machine running GNAT 4.6 on Linux tasks easily max out all available cores at 100%.
