You may want to take a look at section 4.2 “Calculating Occupancy” in the OpenCL Best Practices Guide: In fact you can use the CUDA calculator spreadsheet, or the Compute Visual Profiler (which will show you the occupancy for you kernels).
Yes but in CUDA I can get the resource usage when compiling the .cu file using the -v option to nvcc.
Is there an equiv in OpenCL or I should run the OpenCL visual profiler to get the occupancy??
Can I get the numbers in compile time?

Just use -cl-nv-verbose option on clBuildProgram. Get the register usage for your kernel.
