Surely, you too have been frustrated, while single-stepping optimized programs in symbolic debuggers, by the Brownian motion in the source code, and by never being sure, when you reach a certain source line (if you can reach it at all), whether or not earlier lines have taken effect. Our frustration is about to be significantly alleviated, thanks to two new pieces of technology about to be contributed to the GNU toolchain.

I attended the recent Issaquah and Kona ISO C++ standards meetings, representing Red Hat and the GCC project, and helping to complete the C++17 standard. As usual, I spent the majority of my time in the Library Working Group (LWG) sessions, but also took part in a subgroup focusing on the Filesystem library, more on that below.

The March/April C++ meeting was back in Kona, Hawaii again, only a year and a half after the last Kona meeting. As usual, Red Hat sent three of us to the meeting: Jonathan Wakely, Torvald Riegel, and me.

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in March 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. The major topics of work of the week were (1) further polishing of the parallel algorithms in the C++17 draft, (2) making progress on the executors proposal (which provides mechanisms to control how parallel work is executed, for example on which resources), and (3) continuing work on proposals targeting the Concurrency Technical Specification version 2. We also discussed an important aspect of enabling standard C++ code to execute on GPUs, which is a topic that several people in SG1 have a lot of interest in — I certainly do, for example.

In this article, I want to provide some background details about our recently developed demonstration video – “Running Game of Life across multiple architectures with Red Hat Enterprise Linux“.
This video shows the Game of Life running in a heterogeneous environment using three 64-bit hardware architectures: aarch64 (ARM v8-A), ppc64le (IBM Power little endian) and x86_64 (Intel Xeon). If you are not familiar with the rules of this cellular automaton, they are worth checking out via the reference above.

A few years back (2013-2016) in I was working as a C++ Software Development Engineer at Intel on a monolithic product with a backend written in C++ and a web frontend written in Java. The product was shipped complete with hardware and as a VMware image.

Today, we are announcing the general availability of Red Hat Software Collections 2.4, Red Hat’s latest set of open source web development tools, dynamic languages, and databases. We are also announcing Red Hat Developer Toolset 6.1, which helps to streamline application development on Red Hat Enterprise Linux by giving developers access to some of the latest, stable open source C and C++ compilers and complementary development tools.
New language additions to Red Hat Software Collections 2.4 include:
- Nginx 1.10
- Node.js v6
- Ruby 2.4
- Ruby on Rails 5.0
- Scala 2.10
