GNAT and OpenCL

GNAT and OpenCL

[Jerry]

Does anyone know if there is going to be a GNAT that takes advantage
of OpenCL (Open Computing Language)?

I just took a quick look at the OpenCL documentation.  To me it looks
like it is relatively trivial to use OpenCL from Ada, if you just want
a thin binding, and don't mind writing your OpenCL kernels in OpenCL.

If you want to be able to compile pure Ada as OpenCL, then it seems to
be a much larger problem.  The compiler would have to decide which
parts of the program to run as OpenCL kernels.  And it would have to
compile those parts into OpenCL source code.  (The latter part of the
problem is something which Aonix seems to know a bit about.)

Greetings,

Jacob

I would say No, because the concept of using a GPU for non-graphical 
uses is a "Safety" concern that the Ada RM might have issue with. 

Also, Ada is still primary a Concurrent language. But it also allows tasks to be 
placed on multiple cpus and/or systems controlled by the Ada RTL and the 
programmer. In this design it can go beyond the scope of the openCL 
without harming the existing hardware or adding layers upon layers of code. 
So, I see no reason for Ada or GNAT to use openCL.

And third, if GNAT wanted to try openCL, first GNU GCC would need to 
support the object code needed for CPU/GPU/DSP and openCL.  And GPU 
companies are not that friendly to the GPL and GNU groups.

Could you expand on what you mean by this?

This is implicite, not explicite.

It could be probably implemented as non-GCC backend.
