Hey folks,
I am trying to some data from the host to the device constant memory. But on doing so, I am getting the following error at the end of kernel call: “Invalid Device Symbol”
I am initialising constant memory in the following way:
__device__ __constant__ int nvert_dev;
I am copy data into the memory like this in the host function:
cudaMemcpyToSymbol(&nvert_dev, &nvert, sizeof(int), 0, cudaMemcpyHostToDevice);
Likewise, I am copying 9 floats and 2 integers.
Error again: Invalid Device Symbol.
Please throw some light.
