Hello,

I have been working on a kernel for some simulation application where I am using a defined data Structure inside my kernel. I am however having some issues with it and was hoping for some help. My program keeps dying at a certain point in my kernel. Here is the code in question:

Data Structure
Code :
struct TLM_node {
	float v1;
	float v2;
	float v3;
	float v4;
};
typedef struct TLM_node nodeTLM;


Code :
__kernel void meshTLM_scatter_kernel(
	__global nodeTLM* inputMesh,
	__global nodeTLM* outputMesh,
        __global float* test,
	__local nodeTLM* subMesh)
{
	// Block, Thread and global ID's.
	// Local and Global work size dimensions
	// Block index
    int blockX = get_group_id(0);
    int blockY = get_group_id(1);
 
    // Thread index
    int threadX = get_local_id(0);
    int threadY = get_local_id(1);
 
	// Local Work Group Size (x and y)
	int localWidth = get_local_size(0);
	int localHeight = get_local_size(1);
 
	// Global work size
	int globalWidth=get_global_size(0);
	int globalHeight=get_global_size(1);
 
	// Global id of this thread
	int globalX=get_global_id(0);
	int globalY=get_global_id(1);
 
	int col=blockX*localWidth+threadX;
	int row=blockY*localHeight+threadY;
// Just a test
	if(threadX==0 && threadY==0){
		subMesh[0]=inputMesh[0];        // Kills my program
        // subMesh[0].v1=inputMesh[0].v1  // Does not kill my program
		test[0]=subMesh[0].v1;
	}
 
}

I can't figure out why I am unable to copy an entire node (nodeTLM) from my inputMesh variable however I can copy individual structure elements.

Thanks for any help you can offer,

I feel like it might just be a stupid mistake.
