HPX 1.4.0 Released!

The STE||AR Group is proud to announce the release of HPX 1.4.0. This is a big release! We’ve added numerous new features, continued work on modularizing and making HPX lighter, and all-round improved usability, stability, and performance. Thank you once again to everyone in the STE||AR Group and all the volunteers who have provided fixes, opened issues, and improved documentation.

Download the release from our release page. Please note that we will not be providing downloads from stellar-group.org or stellar.cct.lsu.edu anymore.

The highlights of this release are:

  • We’ve added collectives, resiliency, and component checkpointing.
  • HPX now has support for stackless threads that can be used to reduce task overheads in situations where a task never needs to be suspended.
  • We’ve continued modularizing HPX and have in the process improved compilation speed with networking turned off and made compiled Boost libraries optional in some configurations.

Please see our release notes for a full list of changes as they contain important information on deprecations and breaking changes. If you have any questions, comments, or exploits to report you can reach us on IRC (#stellar on Freenode), or email us at hpx-users@stellar.cct.lsu.edu. We depend on your input!
