OneTbb 2021 is not compatible with parallel STL, what is the way forward?

[AlyaMx]

Hi there,
We are building an analytics application that uses Parallel STL. So far the code links to the tbb library version 2020.3.
We recently tried upgrading to the latest version of the library (oneTBB 2021) (to take advantage of its cmake build configuration) but we quickly understood that it is not compatible with Parallel STL as per the release notes.
So, I am wondering if there is a plan to upgrade Parallel STL so it is compatible with the new tbb version?
Thanks in advance for your help,
Best,
Alya

Same problem. Any update here ?

Hi @AlyaMx, @bduclaux,
Parallel STL has already been updated in libstdc++ (https://github.com/gcc-mirror/gcc/blob/master/libstdc%2B%2B-v3/include/pstl/parallel_backend_tbb.h#L71-L75) to support 2020.3 and oneTBB 2021 both.

@AlyaMx, it seems that problem is solved. Can you check you on your side ?

@AlyaMx, please re-open if the problem still exists

Not sure if I should open another issue, but it seems that at least with GCC12, there are memory leaks when using PSTL with TBB backend (elalish/manifold#787). It works fine with clang using libc++. Not sure if gcc 13 works, not yet checked. GCC 13 works.
