CERN plans migration of accelerator-control systems from Red Hat Enterprise Linux to Debian
The research organization aims to shift more than 2,200 industrial computers to Debian 13 by the end of 2026, citing hardware compatibility concerns.
The short version
- CERN is transitioning more than 2,200 industrial computers and embedded devices in its accelerator-control infrastructure to Debian 13 by the end of 2026.
- The decision follows a long history of relying on Red Hat Enterprise Linux, CentOS, and Scientific Linux for operational computing.
- CERN cited Red Hat's default use of the x86-64-v2 microarchitecture requirement, which it regarded as forced hardware obsolescence, as the decisive factor for the change.
- The full scope of the migration across CERN's broader scientific and server infrastructure remains unconfirmed.
Key facts
- CERN intends to migrate more than 2,200 industrial and embedded systems controlling accelerator infrastructure to Debian 13 by the end of 2026.[Slashdot]
- CERN previously relied on Red Hat Enterprise Linux, co-maintained Scientific Linux, transitioned to CentOS in 2015, and evaluated CentOS Stream before choosing Debian.[Slashdot]
- CERN identified Red Hat's default implementation of the '-march=x86-64-v2' compiler flag as the primary trigger for leaving the ecosystem, characterizing the move as forced obsolescence of older hardware.[Slashdot]
What remains uncertain
- It is not yet clear whether the migration to Debian extends to all general server infrastructure or which specific scientific-research computing systems are included.[Slashdot]
