From the looks of gcc 6.0, it appears that gnu_parallel STL is slated to become part of the release.
Could you be more specific about what you are talking about and where you got your information?
Parallel mode has been a part of libstdc++ for several years: https://gcc.gnu.org/onlinedocs/libstdc++/manual/parallel_mode.html
Am I right in believing that gnu_parallel STL code is not simd vectorized?
It is not manually vectorized, but the compiler is free to do it if it can.
Will there be an option to change this? PR60117 may be related in that it is a case where simd reduction is avoided with OpenMP. It's still marked unconfirmed even though I see that a useful discussion was appended over a year ago.
