Are you sure they mean cores? Millions of cores would bring less than
nothing as the memory will be the bottleneck.
Speaking about the future of parallelism it IMO lies with transputer-like
architectures rather than with multi-cores. Ada looks good with either
paradigm, better with multi-cores, though.
Considering transputers and massive parallelism, I think that Annex E is a
non starter. In the hey day of transputers I fancied the idea of tasks
running on separate transputers making entry calls transparently through
the links. One problem with that is the model of shared memory Ada entry
calls deploy. To make parallelism working on such architectures Ada must
better abstract away by-reference/by-value semantics, allowing marshaling
working for most objects.
