CSL: Facilities: Cluster Computers

The C. S. Department maintains a small cluster of 57 (1856 cores) machines for general computing. The machines are in a round-robin DNS configuration, and can be accessed by using the alias linux.cs.duke.edu. The cluster is comprised of the following machine configurations:

10x Tensor TXR231-1000R D126 Intel(R) Xeon(R) CPU E5-2640 v4 @ 2.40GHz (512GB RAM - 40 cores). Each of the machines has 2 Nvidia Tesla P100s, and 1 Nvidia 2080 RTX Tis.

The machines are set up to use Sun Grid Engine for batch job submission. Please see the lab instructions for using this system. The compute cluster machines are on a 3-4 year replacement cycle, so any machine in the cluster should be no more than four years old. You can use the program cluster_scan or qstat to monitor the cluster.

You can also log into our experimental slurm machine using your NetID and NetID password. 

Please be aware that compute cluster machines are not backed up. Users should copy any important data to filesystems that are backed up to avoid losing data. In addition, try to be cognizant that this is a shared resource. Please minimize the network traffic for shared resources like disk space. If you need to read and write lots of data, please copy that to local disks, compute the results, and store the results on longer term storage.
