Is there any reason why we can not have OpenCL on Amiga OS 4.X?

You can compile shaders with Warp3D nova (if you have the right radeon hd card), so I guess it does support OpenCL, or something like that.

Thanks, I found out that OpenCL was being added back in 2012 to open source drivers.
The thread at Aros-exec mentioned Nouveau.

It will need to be ported to AmigaOS as we dont have an opencl to spir compiler now
What do you want to use OpenCL for ?

@thellier

If I understand correctly the driver that is available to OS4.1 FE and the video cards being used should be capable enough.

I guess I am a solution looking for a problem.

This is because AOS4 has no Interfaces for OpenCL

Quote:

OpenCL (Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators.

Or did you mean OpenGL?

Quote:

Open Graphics Library (OpenGL) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.

This was OpenGL nor OpenCL

@OneTimer1

OpenCL could bring one more thing to Amiga Land.

If the Amiga is a "fun machine", then what resolutions and frame rates are we expecting while playing games?

IIUC you need compute shaders for OpenCL which Nova doesn't do at the moment.

OpenCL can use the CPU as well thhough, but with a single thread there's not much advantage to it.

Not to mention that OpenCL on CPU is ALWAYS slower than native code.

The video cards certainly but the software to compile/run the code has not been ported (I dont know if it is difficult or easy but just not done)

Perhaps you can compile OpenCL to Spir on an other platform buuut there is no Amiga software to run this spir code on the card
I mean Nova can run spir code for the shaders but not as a generic "program"

@thellier

Thanks everyone, I could see PPC Linux on an X5000 being helpful in this case.
