Host name: 141.142.227.55 HardwareSuperMicro SYS-4028GR-TR X10DRG-O+-CPU motherboard 2x Intel Xeon CPU E5-2620 v3 @ 2.40GHz 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
Nodes 1-5 Node 6Node 1 Node 2 Node 3 Node 4 Node 5 Node 6 Node 7
Node 8 Software- CentOS 7
- CUDA 8.0
- PGI 16.10
- Intel ICC 16
| Usage notes: - nano (141.142.227.55) is the head node of the cluster, it should not be used for any computations!
- nodes 1-5 do not have NVIDIA GPUs; they can be used for CPU-only workloads
- node 6 has 1 NVIDIA P100 GPU
- node 7 has 4 NVIDIA K40 GPUs
- node 8 has 8 NVIDIA M40 GPUs. These are very good for deep learning if code is single-precision.
- 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 https://kb.iu.edu/d/avmy 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
