/*
* This use case consists of CUDA producer and CUDA consumer(s).
* It makes use of the CUDA runtime toolkit.
*
* There are two packet elements, a large data buffer and a small
* buffer containing a CRC checksum value.
*
* The producer operation is very simple. It takes a local source buffer
* filled with simple data, and issues a CUDA command to asynchronously
* copy it to the packet's data buffer. It generates a checksum from the
* source buffer and puts that in the packet's CRC buffer.
*
* The consumer(s) similarly issues a CUDA command to copy the packet's
* data buffer to a local buffer. When finished, it generates a checksum
* from the the local copy and compares it to the value in the packet's
* CRC buffer.
*
* The data buffer is processed through the CUDA engine, with commands issued
* asynchronously. Sync objects must be used to coordinate when it is safe
* to write and read the buffer. The CRC buffer is written and read directly
* through the CPU. It uses immediate mode and it is not necessary to wait
* for the sync objects before accessing it.
*
* In addition to the normal case where producers signal sync objects that
* consumers wait for, and vice versa, this use case also needs the
* producer to be able to wait for the fences it generates, in order
* to protect its local buffer from modification while still in use.
* So this use case also provides an example of CPU waiting for fences.
