The mutant cluster currently consists of 32 Dell PowerEdge Servers, along with 15TB of network mounted storage on a Dell PowerEdge 2850 and a Dell R500. Of the compute servers, most (24 of them) have the following configuration:

Quad Core Xeon L5410, 2x6M cache, 2.33Ghz
1333 Mhz Front Size Bus
24GB DDR 266MHz RAM
1TB SATA drive
Dual On-Board 10/100/1000 NICs
64 bit FC8 kernels

Storage: The Mutant cluster machines can access shared storage on CEREBRO, a Dell PowerEdge 2850 running Fedora 2 with 2GB RAM. 1.3 Terabytes of storage is available in a RAID-5 configuration. (CEREBRO is for file services only, and not for login use).  More storage is on AVALON, roughly 3.6TB. Note that the Linux machines will mount your home directories off of NFS.  To get access to per-node local storage, use /local/home/yourlogin. To get access to shared storage, use /cs/mutant/yourlogin and /cs/avalon/yourlogin.

We have another 12TB storage server coming, and the new server will take over main storage duties and be renamed AVALON. At that point, AVALON is renamed blackbird, and becomes a 32GB memory-heavy compute server.

Here are a couple of basic tools for working with the cluster.  Each perl script runs the same command over ssh across all machines in the cluster.  To use them, you need the nodename of each machine in the cluster.  The list of nodes is in this file here.

Note, you should first set up remote ssh access to these machines by storing your public key and authorization on your NFS home directory. To automate commands, be sure to use public-keys with null passphrases, or set up your ssh-agent on the local machine. To avoid having to "accept" ssh hostkeys from each machine, download this hostkey file and append it to your .ssh/known_hosts file.

• You can run the same command across each machine by running a perl script to automate remote commands over SSH.  Execute remote commands with mcmd.pl.

For example, you can do a 'ls -a' on each machine with:


mcmd.pl -n mnodes.lst 'ls -a'

• You can also copy files to each machine over SCP, by using mfiles.pl. Note that a simpler way to share files is to just place them on the shared file server.
  

For example, you can copy file X to each machine with:


mfiles.pl -n mnodes.lst -f X
