Do I understand it correctly that the PDL:PP loops are not
subject to this splitting?
Formerly, it was suggested [1] that a kind of FORALL construct
is to be implemented. I wonder, wouldn't it be better to have
something like the ‘with’ (e. g., [2]) SAC [3] operator
implemented instead?
Also, my understanding is that the transparent utilization of
GPU's will require dynamic GPU code generation. I wonder, may
dynamic /CPU/ code generation be considered for PDL just as
well? (I have some ideas that will demand such a facility.)
TIA.
