Porting GPU kernels to Altera boards

[Altera_Forum]

Hello! 

I am investigating porting some kernels from AMD GPU to Altera.  These kernels make heavy use of OpenCL images and local memory. They require OpenCL 1.2 support.  A few questions:  What version of OpenCL is supported ?  What kind of performance can I expect from OpenCL images ? On GPU, with video memory, images are the preferred way of working with image data.  Do people ship OpenCL kernels? Or do they eventually re-write using Verilog or VHDL ?  How fast will an OpenCL kernel be relative to the same logic written with VHDL ?  Any insight into any/all of these questions would be greatly appreciated.  Thanks!  Aaron

But I'm surprised Altera only supports OpenCL 1.0. Some of the posts mention shared virtual memory, an OpenCL 2.0 feature. Is this overview up to date?

i can tell you that open CL 2.0 is never in the picture for Altera SDK, i believe was not been validated as well, as that had been stated clearly in some document, i read that somewhere before.

Thanks, Tony. Are you saying that Altera will never support 2.0 ?

Hi, i believe this is not the case, probably is only for the time being with out the open cl 2.0 in the road map, i believe sooner or later it may support that. maybe sooner.

I think all still with open CL 1.0 now.... you may see unpredictable error and surprise then try to link with open CL 2.0 calls.

Thanks. Do Altera employees frequent this board? It would be nice to hear confirm or denial from company. 

 If I can't use 1.2, then its not worth the effort to port.

oh.. i recall where i saw this statement. they did mentioned this is for open cl 1.0 

 "The Altera SDK for OpenCL does this and conforms to the OpenCL 1.0 standard"  https://www.altera.com/products/design-software/embedded-software-developers/opencl/overview.html
