BIOS

IRC, Adriaan did

  • Load "optimized defaults"
  • Disable Hyper-Threading
  • Disable "Turbo Mode" (Turbo Boost)

System

scala@scalabench:~$ cat /etc/debian_version
8.8

Init System

Debian 8 uses systemd by default.

  • systemctl to list all services
  • systemctl status cron to show status of a service

Configuration

Some changes done to the system

Allow sudo without password

sudo visudo, added the following lines (https://askubuntu.com/a/147265, https://serverfault.com/questions/294661/how-to-grant-sudo-rights-only-to-specific-script-files)

# scala can sudo without password
scala ALL=(ALL) NOPASSWD: ALL

# jenkins can sudo benv
jenkins ALL=(ALL) NOPASSWD: /home/jenkins/workspace/compiler-benchmark/scripts/benv

Add the backports repo

sudo nano /etc/apt/sources.list.d/jessie-backports.list, add deb http://ftp.debian.org/debian jessie-backports main, run sudo apt-get update

Backports are only installed on demand (sudo apt-get -t jessie-backports install package).

Disable nfs

  • sudo systemctl disable nfs-common
  • sudo systemctl disable rpcbind

Disable exim4

sudo systemctl disable exim4

Installed packages

  • sudo apt-get install git
  • sudo apt-get install jq
  • perf: sudo apt-get install linux-tools-3.16
  • cset: sudo apt-get install cpuset
  • sudo apt-get install numactl
  • cpupower (from backports): sudo apt-get install linux-cpupower
