Interactive C++ for Data Science

by Vassil Vassilev, David Lange, Simeon Ehrig, Sylvain Corlay

From the article:

In our previous blog post “Interactive C++ with Cling” we mentioned that exploratory programming is an effective way to reduce the complexity of the problem. This post will discuss some applications of Cling developed to support data science researchers. In particular, interactively probing data and interfaces makes complex libraries and complex data more accessible users. We aim to demonstrate some of Cling’s features at scale; Cling’s eval-style programming support; projects related to Cling; and show interactive C++/CUDA...

CLion 2020.3 EAP: Postmortem Debug With a Core File

by Anastasia Kazakova

From the article:

In the previous 2020.3 EAP build we were focused on giving run/debug configurations and CMake profiles more flexibility in CLion, and at the same time we introduced a bundled tool for collaborative development and pair programming. In this EAP update we are adding one of the most long-awaited features in debugger – postmortem debug with a core file!

Teresa Johnsons Center Keynote: ThinLTO Whole Program Optimization: Past, Present and Future

by Jens Weller

From the article:

Whole program optimization enables higher performance in C++ applications, because of the expanded scope for analysis and optimization. Traditionally, whole program optimization is not scalable in memory or time, and doesn't support effective incremental builds. ThinLTO (Thin Link Time Optimization) is a new compilation model that...
