cuda - OpenCL application with 3 different kernels -


i started opencl , want port app have in cuda. problem i'm facing kernel stuff. in cuda have kernel functions in same file, on contrary, opencl asks read file kernel source code , other stuff.

my question is: can have 1 single file kernel functions , build program in opencl or have have 1 file each of kernel functions?

it nice if give little example.

the difference between opencl , cuda (in specific regard) cuda allows mix device host code in same source file, while opencl requires load program source external string , compile @ runtime.

but nevertheless absolutely no problem put many kernel functions single opencl program, or single opencl program source string. kernels (say c api kernel objects) extracted program object using respective function names.

pseudocode simplifying opencl's ugly c interface:

single opencl file:

__kernel void a(...) {} __kernel void b(...) {}

c file:

source = read_cl_file(); program = clcreateprogramwithsource(source); clbuildprogram(program); kernel_a = clcreatekernel(program, "a"); kernel_b = clcreatekernel(program, "b");

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
