The Mutant Cluster


Mutant Reservation System, Cluster Statistics

   Cluster Configuration Information

The mutant cluster currently consists of 32 Dell PowerEdge 1750 Servers, along with 1.3TB of network mounted storage on a Dell PowerEdge 2850. Each server (including ProfessorX and Magneto) has the following configuration:
2.4 GHz/512K Cache Xeon
533 Mhz Front Size Bus
2GB DDR 266MHz RAM
2X64/133 MHzPCI-X Video RAM
36GB SCSI 10Krpm HDD
Dual On-Board 10/100/1000 NICs
Fedora 2.6.x SMP 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). 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 CEREBRO's shared storage, use /cs/mutant/yourlogin.

   Cluster Tools

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.
