GSoC’17: Come and code a STE||AR Summer with us!

The STE||AR Group is honored to have been selected as one of the 2017 Google Summer of Code (GSoC) mentor organizations! This program, which pays students over the summer to work on open source projects, has been a wonderful experience for the past three years that we have been accepted by the program.

GSoC 2016 Wrap-up

This summer the STE||AR Group was proud to mentor four students through Google’s Summer of Code program. These students worked on a variety of projects which helped improve our software, HPX. This Library is a distributed C++ runtime system which supports a standards compliant API and helps users to scale their applications across thousands of machines. The improvements that

Vectorized C++ Parallel Algorithms with HPX

In preparation for my talk at CppCon 2016 last week I decided to have a closer look at the possibility to add vectorization to HPX’s parallel abstractions1The slides for this talk can be downloaded here. The goal was to avoid using compiler specific extensions while enabling vectorization support. At the same time, I wanted to be able to integrate this with the already existing parallel algorithms in HPX, proving again that higher level APIs and best possible performance go hand in hand in HPX.

GSoC 2016 Participants Announced!

We can now announce the participants in the STE||AR Group’s 2016 Google Summer of Code! We are very proud to announce the names of those 6 students who this year will be funded by Google to work on projects for our group.

These recipients represent only a handful of the many excellent proposals that we had to choose from. For those unfamiliar with the program, the Google Summer of Code brings together ambitious students from around the world with open source developers by giving each mentoring organization funds to hire a set number of participants. Students then write proposals, which they submit to a mentoring organization, in hopes of having their work funded.
