System Description

Host name:


  • SuperMicro SYS-4028GR-TR
    • X10DRG-O+-CPU motherboard
    • 128 GB DDR4 (8x 16 GB Micron 2133 MHz 36ASF2G72PZ-2G1A2)
    • 8 PCI-E 3.0 ports, switched
  • Mellanox MT27500 Family [ConnectX-3] QDR IB
  • 1x 256 GB Samsung SSD 850


  • CentOS 7
  • CUDA 8.0/9.1
  • PGI 16.10
  • Intel ICC 16

Usage notes:

  • nano ( is the head node of the cluster, it should not be used for any computations!
  • to get access to a particular node for interactive use, please use qsub.
    • e.g., to get one GPU and one CPU core on node 7 for 1 hour for interactive use:
      • qsub -I -l nodes=nano7:ppn=1:gpus=1,walltime=3600
    •  e.g., to get entire node 1 for 1 hour for exclusive interactive use:
      • qsub -I -l nodes=nano1:ppn=12,walltime=3600
  • interactive jobs are limited to 12 hours maximum walltime per job. batch jobs are not limited.
  • better yet, do not allocate nodes for interactive use, instead just submit batch jobs, see for example Job Scripts section at for details. This is a much better way to share computing resources.
  • to see what’s running on the cluster, just run qstat
  • this is a shared resource, please keep in mind that other users are using it as well; do not take over the system beyond what you really need.
  • home directory is cross-mounted, but there is very limited storage size
