HPX V1.9.1 (August 4, 2023)
HPX V1.9.1 (August 4, 2023)#
This point release fixes a couple of problems reported for the V1.9.0 release. Most importantly, we fixed various occasional hanging during startup and shutdown in distributed scenarios. We also added support for zero-copy serialization on the receiving side to the TCP, MPI, and LCI parcelports. Last but not least, we have added support for Visual Studio 2019 and gcc using MINGW on Windows, and also support for gcc V13 and clang V15.
HPX headers are now made consistently named the same as their standard library counterparts, e.g. #include <thread> now corresponds to #include <hpx/thread.hpp>. This significantly simplifies porting existing standards conforming codes to HPX.
A lot of work has been done to improve and optimize our network communication layers. Primary focus of this work was on the LCI parcelport, but we have also cleaned up and improved the MPI parcelport.
Additionally, we have continued working on our documentation. The main focus here was on completing the API documentation of the most important API functions. We have started adding migration guides for people interested in moving their codes away from other, commonplace parallelization frameworks like OpenMP.
