I can't say that my critiques are based off of personal experience. But mostly about microbenchmarks I've read that other people have talked about. I am probably a bit out of date, since its been a while since I last played with OpenMP.

I'm looking at the benchmarks I used to look at, and they're all from 2014 or earlier. So maybe I really should double-check modern implementations. We all know GCC 4.x and LLVM 3.x are an eternity ago, so I probably should revisit their performance.

For example: https://www.phoronix.com/scan.php?page=article&item=llvm_cla...

And back then, it was pretty well known that OpenMP implementations were slower than commercial (such as Intel ICC or IBM's OpenMP implementation).
