Red Hat at the ISO C++ Standards Meeting (July 2017): Parallelism and Concurrency

By Torvald Riegel August 29, 2017August 23, 2017

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in July 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. We discussed several synchronization-related proposals, improvements for futures, and, of course, executors. Also, I proposed a few steps that the SG1 community could take to get more efficient in how it conducts its work, which are all inspired by how successful open source projects work.

Red Hat at the ISO C++ Standards Meetings (November 2016, Issaquah, and February 2017, Kona): Library

By Jonathan Wakely June 30, 2017June 29, 2017

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.

Red Hat at the ISO C++ Standards Meeting (April 2017, Kona): Core Language

By Jason Merrill June 27, 2017June 23, 2017

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.

Red Hat at the ISO C++ Standards Meeting (March 2017): Parallelism and Concurrency

By Torvald Riegel June 16, 2017June 14, 2017

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.

Writing a Linux daemon in C#

By Takayoshi Tanaka June 7, 2017July 27, 2017

When you want to run .NET Core process as a daemon on Red Hat Enterprise Linux, you can create a custom systemd unit. Today I’ll write about two examples of custom systemd unit for .NET Core. The one is a oneshot type for running a .NET Core console application and the other is a simple type for running an ASP.NET Core Web application.

Sometimes things are really easy. This is one of those cases. There are only six steps to creating and running your first .NET program on Red Hat Enterprise Linux (RHEL).

Diagnosing Function Pointer Security Flaws with a GCC plugin

By Aldy Hernandez and Martin Sebor March 17, 2017March 14, 2017

A few months ago, I had to write some internal GCC passes to perform static analysis on the GNU C Library (glibc). I figured I might as well write them as plugins since they were unlikely to see the light of day outside of my little sandbox. Being a long time GCC contributor, but having no experience writing plugins I thought it’d be a good way to eat our own dog food, and perhaps write about my experience.
