can we pass structure pointer to kernel

Respected all,

I am doing some code in cuda. I am new in cuda so i do not know much things related to that.

I want to ask that “Can we pass structure pointer to kernel ?”

waiting for response

Yes, if the structure lives on the device. You can’t pass a pointer to a HOST structure without first copying over the structure to the device.

[There’s a fancy exception to the need to copy the structure using zero-copy memory, but even in that case the pointer you pass in a device pointer.]

can i do like this?

Pixel is the structure having 4 bytes

Pixel *p;

cudaMalloc((PIXEL **)p,size);

//i thing above line will create the buffer on GPU of sizeof(PIXEL)*size

//is it correct? then can i do like this


//passing pointer to the kernel
