This page describes the computer cluster used for computational biology and other purposes, commonly known as van-halen. All information regarding the cluster should be put here so that there isn't a single point of user failure.
The cluster is located in the server room in Lilybank Gardens. The hardware currently consists of a Netshelter VL Value Line - 42U 600X1070MM rack, an HP V1810G 48 Port Ethernet Switch (model number J9660A) and 7 Intel SR1690WBR Server Systems. One of the servers is designated as a head node, which has a DVD-ROM built in (van-halen) and the rest are compute nodes.
The cluster is set up so that the connections between the head node and the compute nodes are on a private network, with the head node also connected to the DCS network. For this purpose, the switch has had two VLANs set up, public(1) and private(100). The ports on the switch are untagged, so traffic cannot span the two VLANs. The head node takes care of routing all traffic between the compute nodes and the outside world.
The cluster is running Rocks 6.0, which is based on CentOS 6.2. This distribution is specifically designed for clusters and has the ability to automatically install and update OS images on each of the compute nodes.
