Modern C++ for High-Performance Computing

The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) has resumed the webinar series on Best Practices for HPC Software Developers, which we began in 2016.

As part of this series, we offer one-hour webinars on topics in scientific software development and high-performance computing, approximately once a month. The next webinar is titled Modern C++ for High-Performance Computing, and will be presented by Andrew Lumsdaine (Pacific Northwest National Laboratory & University of Washington). The webinar will take place on Wednesday, June 12, 2019 at 1:00 pm ET.


Since its creation by Bjarne Stroustrup in the early 1980s, C++ has steadily evolved to become a multi-paradigm programming language that fully supports the needs of modern programmers. Because C++ had its roots in the C programming language, conventional wisdom (and longstanding practice) had been to use C++ in a dichotomous fashion: abstractions for productivity with escape to C for performance. However, C++ today is best viewed holistically — as it is today — rather than as extension of C or even of earlier versions of C++. In this webinar I will give a tour of features from modern C++ relevant to HPC, along with guidelines for their use — and demonstrate that C++ can offer productivity and elegance while sacrificing nothing in performance.
