Review period of Compute library extended till December 30.
Some notes and answers to them that were pointed out during review so far:
* Some of the algorithms could be tuned for a specific hardware
- Library author is working on a auto-tuning solution and improves
* Why OpenCL C API used instead of C++ API?
- C++ API had issues, C API allows a bit more control. No C++ API for
* API is not N4105 compatible, library is not N*** compatible
- This could be easily fixed by a library that will use Compute as a
* Some of the algorithms return futures while other work with command queues
- This is because of the OpenCL design + async chains/futures would be
probably added later
* Not all the types of the Khronos API are supported
- A few types are not documented yet, there's a patch in the works which
would allow the Khronos C++ types to be passed into Compute algorithms
* A few type related errors could be detected at compile time
- This will be fixed, more asserts would be added to runtime only
checkable places. Report issues to the tracker
* On small data sets CPU algorithm would work faster than a GPGPU. How
about implicitly dispatching algo on CPU in those cases?
- The call on whether to execute the algorithm should be left up to the
user. While library author agrees that this would be a useful feature, he
just don't think Compute is the right place for that logic.
* How about providing way to do chains of async operations
- This is a big task that will be solved some day.
* How about providing Boost.ASIO like error handling via throw and
- Implementing an approach like ASIO's wouldn't be that difficult.
Thanks to all the reviewers for spending their time and providing useful
comments so far!
