All nodes in the chart listed below on this page contain one or two network connections.  All node with a processor family of Broadwell, Skylake Silver or Skylake Gold contain 10Gbps Ethernet network interfaces. Other nodes (e.g. Hapertown and Nehalem) have 1Gbps Ethernet network interfaces.  In addition, some nodes, as indicated in the chart, include an [[wikipedia:InfiniBand|Infiniband]] interconnect. This is an alternate high-speed, low-latency network connection. Currently ELSA utilized Infiniband FDR which provides 56Gbps speeds. You can control whether your job uses the Infiniband interface by modifying your SLURM job submission script.
All nodes in the chart listed below on this page contain multiple network connections.  All nodes except gpu-node006 through gpu-node008 contain 25Gbps Ethernet network interfaces. The gpu-node006 through gpu-node008 nodes contain 10Gbps Ethernet network interfaces.

== Network Storage ==
The ELSA cluster utilized network based storage that is shared among all nodes for storing personal files, project/research files, course files and the HPC applications. There are two identical storage servers. One is located in the STEM cluster room and another in the Green Hall datacenter.  Data from the STEM storage server is regularly (i.e. weekly) replicated to the one in Green Hall. The is a total of approximately 2PB of raw storage (about 1.2PB of usage storage of redundancy and spares are accounted for). The storage server is Linux-based utilizing the [https://zfsonlinux.org/ ZFS on Linux filesystem] and [[wikipedia:Network_File_System|NFS]] for sharing with the cluster nodes. It is based on the [http://disruptivestorage.org/ Disruptive Storage Workshop] from the [https://www.jhsph.edu/ Johns Hopkins School of Public Health and BioTeam].
The ELSA cluster utilized network based storage that is shared among all nodes for storing personal files, project/research files, course files and the HPC applications. There are two pairs of identical storage servers. One pari is located in the STEM cluster room and another in the Green Hall datacenter.  Data from the STEM storage servers are regularly (i.e. nightly) replicated to the ones in Green Hall. The is a total of approximately 6.3PB of raw storage available. The storage servers are Linux-based utilizing the [https://zfsonlinux.org/ ZFS on Linux filesystem] and [[wikipedia:Network_File_System|NFS]] for sharing with the cluster nodes.

== Data Transfer Node ==
A [https://fasterdata.es.net/science-dmz/DTN/ data transfer node (DTN)] is used for transferring large files in and out of a cluster. It is designed to handle high-speed, high-volume transfers. The ELSA DTN contains 12TB of disk storage for temporarily holding file transfers. It also has a 40Gbps Ethernet interface and Infiniband FDR interconnect to maximize throughput.
A [https://fasterdata.es.net/science-dmz/DTN/ data transfer node (DTN)] is used for transferring large files in and out of a cluster. It is designed to handle high-speed, high-volume transfers. The ELSA DTN contains 122.9TB (raw) of SSD storage for temporarily holding large file transfers. It also has a 100Gbps Ethernet interface to maximize throughput.

The following describes the contents of columns in the tables below.
* '''Node Name''' = name of the node server. Login nodes (login001, login002, login003, login004) are accessible via the '''elsa.hpc.tcnj.edu''' load-balancer (e.g. using SSH) from the campus network (wired or wireless) or via the [https://tcnj.teamdynamix.com/TDClient/KB/ArticleDet?ID=17531 TCNJ VPN]. The development node dev001 is accessible via '''dev1.hpc.tcnj.edu'''. Other nodes are not meant to be directly accessed.

* '''Queue Membership''' = which queues (SLURM partitions) this node is a member of. Nodes can be a member of multiple queues. Note some queues are used for internal purposes (e.g. remoteviz, interactive) and should not be used for submitting your jobs except under certain conditions. Please see the [[SLURM Partitions]] page for more information on the specification of these queues/partition.

Networking/Interconnects

All nodes in the chart listed below on this page contain multiple network connections. All nodes except gpu-node006 through gpu-node008 contain 25Gbps Ethernet network interfaces. The gpu-node006 through gpu-node008 nodes contain 10Gbps Ethernet network interfaces.

Network Storage

The ELSA cluster utilized network based storage that is shared among all nodes for storing personal files, project/research files, course files and the HPC applications. There are two pairs of identical storage servers. One pari is located in the STEM cluster room and another in the Green Hall datacenter. Data from the STEM storage servers are regularly (i.e. nightly) replicated to the ones in Green Hall. The is a total of approximately 6.3PB of raw storage available. The storage servers are Linux-based utilizing the ZFS on Linux filesystem and NFS for sharing with the cluster nodes.

Data Transfer Node

A data transfer node (DTN) is used for transferring large files in and out of a cluster. It is designed to handle high-speed, high-volume transfers. The ELSA DTN contains 122.9TB (raw) of SSD storage for temporarily holding large file transfers. It also has a 100Gbps Ethernet interface to maximize throughput.

PerfSONAR

PerfSONAR is a network performance testing and monitoring system. It regularly runs tests bandwidth and latency tests and if issues arise, it helps pinpoint the location in the network path causing the issue.

Node Configurations

The following describes the contents of columns in the tables below.

  • Node Name = name of the node server. Login nodes (login001 & login002) are accessible via the elsa.hpc.tcnj.edu load-balancer (e.g. using SSH) from the campus network (wired or wireless) or via the TCNJ VPN. Other nodes are not meant to be directly accessed.
  • Processor Family = the generation of processor in the node. Intel: Skylake Gold > Skylake Silver > Broadwell; AMD: Epyc Genoa > Epyc Rome
  • Available Cores = these are the processing cores that compute jobs can use
  • Reserved Cores = these cores are reserved for system use and not available to user jobs
  • RAM Memory = how much memory the node contains
  • GPU Count = number of GPU accelerators in the node
  • NVIDIA GPU Type = the model of the GPU accelerators in the node. NVIDIA: L40S > RTX2080 >= GTX1080Ti > GTX1080
  • Queue Membership = which queues (SLURM partitions) this node is a member of. Nodes can be a member of multiple queues. Note some queues are used for internal purposes (e.g. remoteviz, interactive) and should not be used for submitting your jobs except under certain conditions. Please see the SLURM Partitions page for more information on the specification of these queues/partition.
