The "Simplify ScopedContextGetterBase::synchronizeStreams" commit looks good.
The "Template ScopedContext on the Queue type" commit looks generally good too, I left some comments that caught my eye that are related to the Product<T> and possibly were not caught by the compiler because that functionality is not used yet.

Not about this PR, but I thought note since it caught my eye. I don't really understand what this function (in conjunction with the commented destructor body) should do. The ScopedContextProduce should store the std::shared_ptr<Event> (e.g. in its constructor), pass it to all Product<T>'s, and record the event ("enqueue to queue"?) in its destructor. Ok, doesn't really matter in practice at this stage where the Product<T> wrapper is not used yet.

I have no idea... so far I've concentrated on cleaning things up, without breaking anything.
Understanding what is missing will come next...

This should also pass the shared_ptr<Event>, but see my other comment #255 (comment).

Move the ContextState class and the ScopedContext class hierarchy outside of the ALPAKA_ACCELERATOR_NAMESPACE namespace, and template them on the Queue type used by the accelerator.

Actually, multiple devices are still not supported, because all device memory operations operate on the first device. |
Move the ProductBase class and Product<T> class template outside of the ALPAKA_ACCELERATOR_NAMESPACE namespace, and template them on the Queue type used by the accelerator.
