Sauron is ITC's newest beowulf cluster. It is a cluster with 159 computational nodes. Each node has two 2.0 GHz Opteron processors and 2 GB RAM. The nodes are connected using a Gigabit ethernet connection. In addition the cluster has 8.5 TBytes of disk space available to it.
Access to Sauron is controlled. Please contact <sdutta at cfa> for access and further information. Once an account has been created from you, log into sauron.cfa.harvard.edu from one of the machines allowed to connect to it. You can only use ssh to connect to Sauron, and only from a certain list of machines. Contact us for more information on adding your machine to the allowed list. If you don't want to have to type in your password everytime you login from your machine to Sauron, you can generate a key and place the public key in the file authorized_keys in the .ssh (note the . in the beginning) directory. In addition, if you want open X-windows from Sauron, you will need to allow X-tunneling over ssh. On linux machines you can do this, by using the flag -X to ssh. Please read the manual for the ssh client on your machine for more information. Additionally please note that the Sun version of ssh used on machines managed by the computational facilities at the Center for Astrophysics is broken. They will not allow daisy chaining X tunneling over ssh through multiple machines.
All ITC faculty automatically have access to Sauron. Simply email a request to <sdutta at cfa> for login information. All other members of ITC need an email from any ITC faculty member expressing support for their use of Sauron.
