DUDA

Hi Gor!

Then I guess you think C++ is a completely pointless waste of 
time because of C also? CUDA carries a subset of C++, while 
OpenCL does not, allowing for OO-programming, metaprogramming, 
etc. Adding to that, there is also strong IDE support (editing 
and debugging) for CUDA, while for OpenCL I have yet to find that 
(which would of course also be an issue for "DUDA"). Not 
_completely_ pointless yet, right?

Anyways, the original question was about GPU-oriented languages 
and D.

As a variant to CUDA in D (DUDA): If there was a way to use a 
subset of D (à la C++AMP) and have that turn into GPU and/or CPU 
(using the code-gen/backend of the LLVM CUDA compiler, or compile 
to OpenCL as a target for that matter), it'd be great. I too 
don't like vendor lock-in (CUDA=nVidia) and C++ has it's 
drawbacks as a language. The alternative of OpenCL is too much 
plain C for it to feel modern/productive. An alternative based on 
D could really have a potential of being great!?

To state it as an open question: What would be the D way of 
facilitating GPU(+CPU) programming?

Cheers

Anders
