Jcuda CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES(参数太多?

Question

当我调用函数cuLaunchKernel((时，我的程序崩溃并显示错误，CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES。 这是因为我将 29 个参数传递给我的内核吗？ 如果是这样，是否有任何解决方法？我很确定我需要这些参数进行计算。

Pointer kernelParams = Pointer.to(
Pointer.to(new int[] {n}), 
Pointer.to(new int[] {xRes}), 
Pointer.to(new int[] {yRes}),
Pointer.to(new double[] {camX}),
Pointer.to(new double[] {camY}),
Pointer.to(new double[] {camZ}),
Pointer.to(new double[] {camforX}),
Pointer.to(new double[] {camforY}),
Pointer.to(new double[] {camforZ}),
Pointer.to(new double[] {camupX}),
Pointer.to(new double[] {camupY}),
Pointer.to(new double[] {camupZ}),
Pointer.to(new double[] {fov}),
Pointer.to(new double[] {aspectRatio}),
Pointer.to(in14),
Pointer.to(in15),
Pointer.to(in16),
Pointer.to(in17),
Pointer.to(in18),
Pointer.to(in19),
Pointer.to(in20),
Pointer.to(in21),
Pointer.to(in22),
Pointer.to(new double[] {meshposX}),
Pointer.to(new double[] {meshposY}),
Pointer.to(new double[] {meshposZ}),
Pointer.to(out0),
Pointer.to(out1),
Pointer.to(out2)
);
cuLaunchKernel(function,
32,32,1,
32,32,1,
0,null,
kernelParams,null
);

Answer 1

这是我天真的答案：

正如评论中所建议的，问题与块大小有关。减小块大小修复了错误。减小块大小后，我收到错误：CUDA_ERROR_ILLEGAL_ADDRESS。减小网格尺寸解决了这个问题。
