Hi, the good book "C++17 STL Cookbook" in chapter 9 "Parallelism and Concurrency" describes some of the 69 algorithms that were extended to accept execution policies in order to run parallel on multiple cores. And, according to the provided examples, they all greatly simplify some aspects of parallelization with the standard algorithms.
I'm using Ubuntu 16.04 with upgraded gcc version 7.2.0 (Ubuntu 7.2.0-1ubuntu1~16.04) and the header file <execution> is not present. In the official gcc documentation: https://gcc.gnu.org/onlinedocs/libstdc++/ manual/status.html the support to <execution> is flagged as "no" in the Table 1.5. C++ 2017 Implementation Status, and it seems that it is even not foreseen to be included in the upgraded gcc 8 version: https://gcc.gnu.org/projects/cxx-status.html So, the crucial question about these 69 extended algorithms in the header file <execution> is: are these extended algorithms going to be supported by the next releases of gcc, as they are already supported by Visual Studio, and soon by clang ? Looking forward to your kind feedback about this extremely important aspect of gcc. Marco
