Linux Computing Resource (uschpc)

Systems & Access :: Learning to Use :: Linux Computing Resource

The Linux Computing Resource consists of 1,893 dual-processor nodes and 5 x 16 processor, 64GB large memory servers, interconnected with Ethernet and Myrinet. The basic cluster architecture is shown below followed by a table of available Queues and Nodes.

*Note: Some nodes are privately owned and are therefore unavailable to all users. In addition, nodes are sometimes reserved for specific projects or purposes and therefore temporarily unavailable.

Using the Linux Cluster Resource

The Linux cluster resource (uschpc) runs the USCLinux. You login to uschpc by ssh-ing to hpc.usc.edu, which is the head node and the only node you can log onto directly. The head node should be used only for editing and compiling programs. Computing should be done on the compute nodes. The Portable Batch System (PBS) controls the use of the compute nodes.

A standard user environment includes the default shell (csh) and the given default .cshrc and .login files that source the master.cshrc and master.login files.
