Help with porting a CUDA code to OpenCL

Hi everyone. I am porting a CUDA kernel to OpenCL kernel to execute it on a FPGA (Stratix V). The code looks very similar so it shouldn't be a problem except that this FPGA board supports only O...

I am trying to use atomic functions to see if I can solve this problem but when I compile I get "note: candidate function has been explicitly made unavailable". What does it mean?

I am using double variables in my code.

Thanks
