Therefore, expect some interruptions to the availability of these hosts. Also, if you have any software that needs to be running on these machines, it will likely need to be recompiled with the new compiler. Please, contact me if you have any questions or concerns. Best, Hovanes. -------------- next part -------------- An HTML attachment was scrubbed...

It should be usable on all gluon machines that are running RHEL9. Simply source the environment with: source /gluex/software/gluex_7.3.0_top/gluex_env_boot.csh followed by source /gluex/software/gluex_7.3.0_top/gluex_env_local.csh Since we completed the upgrade of the official version set to root 6.32.20 and c++std=20, the full suite could be compiled without any special instructions. It only has to be rebuilt with ET support before linking it to rootspy during the next run. Please let me know if you experience any problems.

This may cause outages for some of our DAQ, controls, and monitoring systems. The work is preliminarily scheduled for Thursday, January 29 between 2pm and 5pm. Let me know if this would interfere with important activities involving the computing in the Hall D network so that we can reschedule this work. Thanks, Hovanes . -------------- next part -------------- An HTML attachment was scrubbed...
