HPX meets Fedora

With the release of HPX 1.2.0, we added support of HPX to the offical Fedora updates-testing repository. Following packages are available on Fedora 28/29

We provide HPX compiled with the GNU compiler collection, with the OpenMPI compiler, and the MPICH compiler. The hpx-devel packages contains the header files and he hpx-*-examples package contains all the examples compiled with the respective compiler. The purpose of these packages is educational and we hope to lower the entrance point to experiment with HPX. For performance measurements we recommend to compile HPX on the used hardware.

HPX 1.2.0 Released!

The STE||AR Group is proud to announce the release of HPX 1.2.0. This release is the first in our more frequent release schedule. We are aiming to produce one release every six months in an effort to get new features and stable releases out to users more quickly. As a result this release is smaller than many previous releases, but nevertheless contains many important improvements. This release includes among others performance improvements, a new implementation of hpx_main.hpp, scheduler hints, and many stability improvements. This release also removes many previously deprecated features. Make sure you read the full release notes to see which deprecated features were removed.

Thank you to everyone who has contributed from all over the world!

HPX Mailing List Archives Now on Gmane

In order to make searching and accessing the HPX mailing lists easier, we have made the hpx-users and hpx-devel archives available via Gmane.  This service allows users to browse posts through the use of several formats including two web interfaces, an NNTP newsreader, and a RSS feed. These interfaces will help get questions, answers, and other detailed information about HPX out to the public in an easily consumable format. Try it out!

Edit: gmane went out of business a while back. The new links to the mailing archives are now:
