Notes on linux memory management options to prioritize and control memory access using older ulimits, newer cgroups and overcommit policy settings. Mostly as an attempt to keep a desktop environment responsive and avoid swap thrashing under high memory pressure.

Overview

Some notes about:

  • Explaining why current day Linux memory swap thrashing still happens (as of 2016).
  • Mitigating "stop the world" type thrashing issues on a Linux workstation when it's under high memory pressure and where responsiveness is more important than process completion.
  • Prioritizing and limiting memory use.
  • Older ulimit versus newer CGroup options.

These notes assume some basic background knowledge about memory management, ulimits and cgroups.

Build steps to create a (cross-)compiler creating native code executable targeting raspberry pi (RPi), running on MSYS2 and using MSYS2 to compile the cross-compiler

Build Steps

This document details extra that were needed to build the rpi cross-compiler on MSYS2. The original instructions are located on gurucodings.

This cross-compiler has been created targeting the Raspbian Wheezy OS which is based on Debian Wheezy with special support for the Raspberry PI architecture. The version that was installed on my rpi is 2014-06-20-wheezy-raspbian.

Here the version of the various tools currently present in this version of Raspbian (Guest OS):

  • gcc (Debian 4.6.3-14+rpi1) 4.6.3
  • GNU ld (GNU Binutils for Debian) 2.22

A bash script to query a Jenkins server. Use like this: 'checkJenkins.sh <jobname>' and it will query the server with the given job name every 30s. Use like this: 'checkJenkins.sh <jobname> tmux' and it will query the server once and output tmux coloured messages appropriate to display in a tmux status bar. E.g. add this to your .tmux.conf 'set …
