Slurm Configuration Debian based Cluster

Here I will describe a simple configuration of the slurm management tool for launching jobs in a really simplistic cluster. I will assume the following configuration: a main node (for me it is an Arch Linux distribution) and 3 compute nodes (for me compute nodes are Debian VMs). I also assume there is ping access between the nodes and some sort of mechanism for you to know the IP of each node at all times (most basic should be a local NAT with static IPs)

Basic Structure

Slurm management tool work on a set of nodes, one of which is considered the master node, and has the slurmctld daemon running; all other compute nodes have the slurmd daemon. All communications are authenticated via the munge service and all nodes need to share the same authentication key. Slurm by default holds a journal of activities in a directory configured in the slurm.conf file, however a Database management system can be set. All in all what we will try to do is:

• Install `munge

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".
