Linux Cluster Computing
SNS has a 48 node (96 CPU) Beowulf cluster running the 64-bit RedHat Linux Enterprise Server operating system.
Each node of the cluster comprises dual Opteron 1.8GHz CPU's and at least 2GB RAM (16 nodes have 4GB RAM). A master node, apollo, is provided for compiling/debugging and this has 8GB RAM.
A visualization node, vis1, is provided for data analysis using IDL or AVS Visualization Express. vis1 resides in the Astro library where it can be accessed directly for intensive graphics work. A 24" LCD display is provided for this purpose.
A 4TB disk array residing on the master node is shared out to all client nodes. High performance Gigabit switches connect the nodes via a dedicated network.
All job submission must be done via the PBS (portable batch system) queuing software and according to the rules laid out under Job Submission below.
For security reasons the cluster has separate user accounts although the cluster master node apollo does mount the /data filesystem which is also available on other SNS systems.
If you would like an account on the cluster please contact the computing staff. Please note - the cluster is for the use of physics and astrophysics only.
