Simple, good.

The overview of C++20 Range view

by Ryou Ezoe

From the article:

The latest C++ draft at the time of writing incorporated The One Ranges Proposal.

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/n4791.pdf

So what is a Range, anyway? The C++ Standard Comittee member, Eric Niebler, summarised it well in this article:

Eric Niebler – Eric Niebler

Actually, he summarised it all too well to the point that his code became almost unreadable to an average C++ programmer. One might say, it's practically useless. So this article serves as a quick tutorial for the Range view...

Call For Papers: Distributed & Heterogeneous Programming in C/C++

By rodburns | Jan 14, 2019 01:39 AM | Tags: None

The call for papers is now open for DHPCC++19 and closes on 27th January.

DHPCC++, 13 May 2019, Northeastern University, Boston, USA

by the DHPCC++

From the article:

This will be the 3rd DHPCC++ event in partnership with IWOCL, the international OpenCL workshop with a focus on heterogeneous programming models for C and C++, covering all the programming models that have been designed to support heterogeneous programming in C and C++.

Many C++ programming models exist including SYCL, HPX, KoKKos, Raja, C++AMP, HCC, Boost.Compute, and CUDA. This conference aims to address the needs of both HPC and the consumer/embedded community where a number of C++ parallel programming frameworks have been developed to address the needs of multi-threaded and distributed applications. The C++11/14/17 International Standards have introduced new tools for parallel programming to the language, and the ongoing standardization effort is developing additional features which will enable support for heterogeneous and distributed parallelism into ISO C++ 20/23. This conference is an ideal place to discuss research in this domain, consolidate usage experience, and share new directions to support new hardware and memory models with the aim of passing that experience to ISO C and C++.

Topics of interest include, but are not limited to:

  • Future Heterogeneous programming C/C++ proposals (SYCL, Kokkos, Raja, HPX, C++AMP, Boost.Compute, CUDA …)
  • ISO C/C++ related proposals and development including current related concurrency, parallelism, coroutines, executors
  • C/C++ programming models for OpenCL
  • Language Design Topics such as parallelism model, data model, data movement, memory layout, target platforms, static and dynamic compilation
  • Applications implemented using these models including Neural Network, machine vision, HPC, CFD as well as exascale applications
  • C/C++ Libraries using these models
  • Integration of these models with other programming models
  • Compilation techniques to optimize kernels using any of (clang, gcc, ..) or other compilation systems
  • Performance or functional comparisons between any of these programming models
  • Implementation of these models on novel architectures (FPGA, DSP, …) such as clusters, NUMA and PGAS
  • Using these models in fault-tolerant systems

by Rob Irving and Jason Turner

About the interviewee:

Arthur O'Dwyer started his career writing pre-C++11 compilers for Green Hills Software; he currently writes C++14 for Akamai Technologies. Arthur is the author of "Colossal Cave: The Board Game," "Mastering the C++17 STL" (the book), and "The STL From Scratch" (the training course). He is occasionally active on the C++ Standards Committee and has a blog mostly about C++.

Quick Q: How to use auto keyword to assign a variable of type uint32_t or uint64_t in C++

By Adrien Hamelin | Jan 9, 2019 01:09 PM | Tags: c++11 basics

Quick A: Write the type!

Recently on SO:

How to use auto keyword to assign a variable of type uint32_t or uint64_t in C++

I'm assuming you're working with the AAA style suggested by Herb Sutter.

In that case, a nice solution is to simply write:

auto variable_name = uint64_t{ 5000000000 };

This is clear, consistent, and explicitly typed with no nasty C-preprocessor necessary.
