<dt>Device</dt>

<dd>(same naming as in CUDA:) the actual device on which the core ray
tracer runs on. currently, this is the host PC, but eventually it will
be on LRB, and in a different address space, hence the need to
differentiate. 
\n
Also see "driver", "app", and read \ref driver_device_app.
</dd>


<dt>driver</dt>

<dd>(same naming as in CUDA:) the part of the ray tracer that runs on
the _host_ (i.e., _not_ on the "device"). can share data with the app
(same address space). 
\n
Also see "device", "app", and read \ref driver_device_app.

</dd>


<dt>app</dt>

<dd>the actual application written by the user. will use the ray tracer by communicating with the (see:)driver, which in turn will drive the part of the ray tracer that runs on the (see:)host. 
\n
Also see "driver", "device", and read \ref driver_device_app.
