O3 Optimization features

I just want to add that, as explained in the altera optimization guide (http://www.altera.com/literature/hb/opencl-sdk/aocl_optimization_guide.pdf), the resource-driven optimizer will use maximum 85% of the logic. You can however force it to another value if you want.

If you do not specify the maximum logic utilization, the resource-driven optimizer uses a maximum logic utilization of 85%. To enable the resource-driven optimizer with a maximum FPGA hardware utilization of 85%, omit the --util flag, as shown below:

aoc -O3 <your_kernel_filename>.cl

To specify a maximum FPGA hardware utilization percentage other than 85% (for example, 50%), invoke the following command:

aoc -O3 --util 50 <your_kernel_filename>.cl
