About CUG 2027
CUG 2027 runs May 9–13, 2027 in Houston, Texas, with roughly 300–500 attendees. The Cray User Group is a technical conference where supercomputing sites present operational experience, and the 2027 theme is 'Subsurface to Space: HPC at Extreme Scale.'
Who should attend
Attendees include HPE Cray site administrators, national laboratory and supercomputing center staff, and system engineers.
Why it matters
CUG draws almost entirely from sites running large-scale systems, so sessions deal with real operational problems at extreme scale, including parallel storage and I/O. It is one of the more candid technical forums in HPC.
