Performances of CPU backend and CAL backend

Dear All,

I just encountered a strange situation.

I would like to compare the performances (i.g., execution time) between CPU backend and CAL backend. However, I found that their execution time is almost the same whether BRT_RUNTIME = cpu or BRT_RUNTIME = cal. It seems that this environment variable is useless on my computer. Do I forgot something in addition to set the environment variable? How do I make sure that my program is running on CAL backend successfully?
