[Jlab-scicomp-briefs] JLab SciComp updates begin Oct 17: CentOS 6.9, CUDA 8, 9

[Sandy Philpott]

Dear JLab Scientific Computing Users,

Our CentOS 6.5 systems will be updated to CentOS 6.9, to support the new /work fileserver that's ready for production in the coming weeks.  glibc remains at version 2.12, with a minor version number increase. This update includes qcdgpu, qcdkmi, 12s, 12k, 10g, and (i)farm CentOS 6 hosts. 

In HPC, qcdkmi will be upgraded during the IT maintenance day, Tuesday Oct 17, and nodes in 12s, 12k, and 10g will start updating via a rolling upgrade.  qcdgpu will follow on Tuesday Oct 24.   The updated batch nodes will initially be configured as testib or testgpu nodes, so that users can confirm transparent functionality on the interactive and batch systems.  On Oct 24 the updated nodes will be reconfigured as production.

In the farm, ifarm1101 will be upgraded on Thursday Oct 26, with rolling updates to the remaining CentOS 6 farm12 nodes beginning.

For GPU users, CUDA 8 and 9 is being installed. These new versions will be available via their corresponding module.

Please plan for these necessary updates, and save any needed files from qcdkmi, qcdgpu, and ifarm1101.  Direct questions or issues to philpott at jlab.org, 757-269-7152, or via User Support at helpdesk at jlab.org.

Regards,
Sandy
