[Openmp-dev] Public Benchmarks?

There was in article one year ago:
http://www.phoronix.com/scan.php?page=article
<http://www.phoronix.com/scan.php?page=article&item=clang-svn-openmp&num=2>
&item=clang-svn-openmp&num=2

I never came around to confirm the test results and it may look different
for 3.9 now.

 

Regards,

Jonas

Subject: [Openmp-dev] Public Benchmarks?

 

I just noticed that the LLVM page in Wikipedia
(https://en.wikipedia.org/wiki/LLVM ) contains the statement 

 

For run-time performance of the compiled programs, GCC formerly outperformed
LLVM by 10% on average. <https://en.wikipedia.org/wiki/LLVM#cite_note-18>
[18] <https://en.wikipedia.org/wiki/LLVM#cite_note-19> [19] Newer results
indicate that LLVM has now caught up with GCC in this area, and is now
compiling binaries of approximately equal performance, except for programs
using  <https://en.wikipedia.org/wiki/OpenMP> OpenMP.
<https://en.wikipedia.org/wiki/LLVM#cite_note-20> [20]

 

I believe that is wrong (their evidential link is from 2012!), and our
OpenMP performance is now at least comparable with, if not better than, that
of GCC, but I don't have any public benchmarks to prove it. 

 

So, does anyone have any pointers to public articles that show that, so that
we can go in and fix the Wikipedia article?

(Phoronix' latest at http://www.phoronix.com/scan.php?page=article
<http://www.phoronix.com/scan.php?page=article&item=gcc-61-clang39&num=1>
&item=gcc-61-clang39&num=1 doesn't seem to have any OpenMP codes in it, so
that's no use).

 

Thanks
