GPU Coder Build Error

According to official documentation I run a GPUcoder example mandelbrot_count

This is official function,but get error in Check for Run-Time Issues step,

function count = mandelbrot_count(maxIterations,xGrid,yGrid) %#codegen
% Add kernelfun pragma to trigger kernel creation
coder.gpu.kernelfun;

% mandelbrot computation
z0 = xGrid + 1i*yGrid;
count = ones(size(z0));

z = z0;
for n = 0:maxIterations
    z = z.*z + z0;
    inside = abs(z)<=2;
    count = count + inside;
end
count = log(count);

this is My device information, how Can I set the correct setting in this,Thank you

Hi ding barry,

I understand that you are encountering an error while generating CUDA code for the 'mandelbrot_count' function using GPU Coder.

The cause of the error was incorrect code generation configuration settings. To generate the code without any errors, follow the steps below.

• Create a GPU code generation configuration object.

% For mex
cfg = coder.gpuConfig('MEX');

% For static library
cfg = coder.gpuConfig('LIB');

% For Dynamic Linked library
cfg = coder.gpuConfig('DLL');

% For executable
cfg = coder.gpuConfig('EXE');

• Enable or disable required libraries.

% set the value to 'false' to disable
% Enabling Nvidia cuFFT
cfg.GpuConfig.EnableCUFFT = true;

% Enabling Nvida cuBLAS
cfg.GpuConfig.EnableCUBLAS = true;

• Set the required Compiler flags,

% For example
cfg.GpuConfig.CompilerFlags = '--fmad=false';

• Generate the code using ‘codegen’ command

% arg1, arg2 … are the arguments
codegen mandelbrot_count -args {arg1,arg2,arg3} -nargout 1

• You change the configuration settings of code generation in the app itself. In the ‘Check for Run-Time Issues’ screen, on the top right, you can find the ‘settings’ option

• In the settings select GPU Code section, in which you can change the configuration settings.

For more information, refer the following MATLAB documentation,

Hope this is helpful.

@ding barry - Looks like you encountered a bug in GPU Coder. I reported this to the team resposible.

Run-time checks is an optional step in code generation. You can skip this step and move on to code generation and verification. that should run just fine.
