Pitagora: maintenance completed  (https://www.hpc.cineca.it/newsletter/pitagora-maintenance-completed-5/) 

23 June 2026 

Dear Users, 

We are pleased to inform you that the scheduled maintenance has been successfully completed and Pitagora is now fully operational . 

The Booster nodes and GPU login nodes (alias: login-boost.pitagora.cineca.it ) have been patched to address the recent GPU driver vulnerability and have been fully reinstalled. Additionally, login06-ext.pitagora.cineca.it is now back in production. 

Please note that due to the reinstallation, SSH host fingerprints have changed . You may encounter a “REMOTE HOST IDENTIFICATION ERROR” when logging in. If so, please follow the procedure described in the FAQs  (https://docs.hpc.cineca.it/faq.html#i-keep-receiving-the-error-message-warning-remote-host-identification-has-changed-even-if-i-modify-known-host-file) to update your known hosts. 

The new node images for both Booster and DCGP nodes also include a fix for the security vulnerability related to the ptrace mechanism. As a result, the original scope level has been restored, and all debugging and profiling tools relying on ptrace are now fully functional again . 

Best regards, 

HPC User Support @ CINECA
