    2222== Analysis of VLIW instructions == 
    23 Our kernel is directly written in IL. After compilation into a machine code, I analyze the generated VLIW instructions. Results are obtained with fglrx 8.65.4 (Catalyst 9.9) and CAL 1.4beta. Almost 90% of the time, "5870_opt kernel" runs at maximum efficiency (here, I mean more than 4 slots occupied by instructions). It is compared to 83% in the case of our old kernel.
