How to debug (OpenCL2.0 device side) enqueue_kernel reports CL_OUT_OF_RESOURCES?

GPU: Hawaii (R9 295x2)

Code simply like this:

kernel void fit(global const float* a, global const float* b, float c, float d)


queue_t default_queue = get_default_queue();

enqueue_kernel(default_queue, CLK_ENQUEUE_FLAGS_WAIT_KERNEL, ndrange_1D(1),


  kernel2(a, b, c, d);





The program exits as:

Error in clEnqueueNDRangeKernel (-5): CL_OUT_OF_RESOURCES

Note I runs only for ndrange_1D(1), I don't know why out of resources. If enquene kernel2 from host side (parameters a-d are same), no problem.

How to debug this issue?
