Intel® Graphics Technology enables you to offload sections of your code to run on both the CPU, the host, and the processor graphics, the target. While the Intel® compiler by default compiles your code to run on both the host and target, writing an application to run on the target is different from writing an application for the host in the following ways:
The instruction sets used by the host and the target are substantially different.
Only parallel loops can be offloaded to the target.
The compiler includes language extensions to account for these differences. The source code used in this tutorial contains these language extensions to specify the sections that can be offloaded to the target, and that can share data between the host and target. The compiler compiles code to run on both the host and target. You can also use a compiler option to compile the same source code to run on just the host.
