Hi Michal,

Thanks for the link. John Appleyard had let us know late last week that they were refreshing Polyhedron but had not given us his results nor access to the code. I just started looking at the new codes to determine how much of the difference is due to flag selection and will let you know what I find. I also let our application engineering team about the results and they will start to take a look as well.

FYI, our apps team determined that we are missing some opportunities for vectorization in INDUCT and our compiler team is currently implementing these recommendations.

Best Regards,
Mat

Are these new opportunities for vectorization implemented in PGI 11.10?

Hi Michal,

11.10 only contains a few small changes mostly for CUDA. We're working on general enhancements to vectorization which should available in the 12.0 release.

OK ... release 12.1 is out, congratulation!

What about previously announced vectorization enhancements? Are they already implemented?

Is there any significant impact on polyhedron benchmark?

Hi Michal,

Our compiler engineers decided to prioritise some general optimisation opportunities over the specific ones found in INDUCT and MP_PROP_DESIGN. So while I do show a bit of an increase over 11.10 (~6%), the large deltas still do exist. I'll keep bring it up in our weekly performance meetings.
