The NVidia compilers use the <tt>-ta</tt> (target accelerator) option to enable compilation for an accelerator. We use the sub-option <tt>tesla:managed</tt>, to tell the compiler that we want it compiled for Tesla GPUs, and we want to use managed memory. Managed memory simplifies the process of transferring data to and from the device. We will remove this option in a later example. We also use the option <tt>-fast</tt>, which is an optimization option. | The NVidia compilers use the <tt>-ta</tt> (target accelerator) option to enable compilation for an accelerator.

As we can see in the compiler output, the compiler could not parallelize the two loops. We will see in the following sections how to deal with this. | As we can see in the compiler output, the compiler could not parallelize the two loops.
