|
* NvSciStream Event Loop Driven Sample App - usecase #1
|
|
*
|
|
* 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.
