The IBM Spectrum Scale (GPFS) user group is open to all who are using, interested or integrating IBM Spectrum Scale. We have groups across the world, from the UK to the USA and Asia Pacific.

We welcome IBM Spectrum Scale users from a wide range of industries and are not sector-specific. Our current membership base includes representation from media, academia, research, automotive, defense and pharmaceutical industries. 

This group is independent of IBM and run by the community members, and periodically include ecosystem partner speakers. All agendas are created by client users in the community.
