Use registerDoParallel(cl)
The number of parallel workers is already contained in the 'cl' object, so don't specify 'cores'! (If you do that, I suspect you create yet another cluster (a multicore one) which is used but never closed) registerDoParallel() should ideally give an error in your case. Author BCC:ed.
