WSC Cluster - overview
Welcome to the WSC cluster
The WSC cluster consists of IBM AC-922 nodes (2 socket, 22 core Power9 CPUs + 6 Volta GPUs). These are the same nodes used in the Summit supercomputer at ORNL.
The cluster consists of 57 compute nodes, each with with dual socket 22 core CPU and 6 GPUs, plus seven additional nodes dedicated to management functions. Occasionally, a few compute nodes are assigned to specific experiments, thus the maximum number of compute nodes available for regular use at a given time might be less than 57.
Management nodes include login and launch nodes; these nodes have dual socket 20 core CPU and 4 GPUs.
Note: This cluster is in the so-called IBM Yellow zone, thus it cannot access any of the internal IBM resources.
The cluster is intended to be used for the following purposes:
- Advanced research for IBM Research projects.
- Collaboration with external entities on projects of common interest.
- Support IBM business units.
Confidential and Proprietary data
- There should not be any Confidential data stored in WSC; that is, data that requires authorization for its use.
- There should not be any Personal Sensitive Information (PSI) stored in WSC.
- There should not be any Export Controlled data stored in WSC.
If in doubt regarding the classification of some data, do not hesitate to ask for clarification.
The WSC cluster is part of the Covid19 HPC Consortium. To use this resource for CoVID-19 research, interested parties should apply to the Consortium at Covid19-HPC-Consortium
Submit the request form at the link below. Include GSA id and the output from the "id" command, so that admins have the GSA user and group numeric id's.

Non-IBM (external) parties should request access through an IBM collaborator. In addition to access to WSC itself, external parties need to get access to a VPN for connecting to the IBM Yellow zone.
Problems with the cluster need to be submitted through the internal GitHub issues system (https://github.ibm.com/DCS-research/WSC-coral/issues - this link is available only internally to IBM).
Communicate the problem to IBM collaborators so they can file an issue through the internal GitHub issues system.
Documentation at ORNL
ORNL has extensive documentation on Summit; some of that documentation is also applicable to WSC:
- Summit User's Guide
- 2018 Summit Training Workshop (charts in tab "Presentation" at bottom of web page)
- Summit tool for visualizing task placement and affinity
See the User's Guide tab for additional information
