Compute Node Downtime
The following compute nodes will be taken offline (starting at approximately 6pm on 06/05/2008) and reinstalled for performance optimizations:
The following compute nodes will be taken offline (starting at approximately 7pm on 06/05/2008) and upgraded from RHEL4 to RHEL5. Anyone still relying on these systems for RHEL4 compatibility should contact us (firstname.lastname@example.org) immediately.
The CIMS linux machines (desktop as well as compute nodes) will be remotely upgraded from RHEL 5.1 to RHEL 5.2 during the day on Thursday (06/06/2008). This includes a kernel change which will require the machines to be rebooted. The machines WILL BE REBOOTED in the wee hours of the night between 11pm and 3am to complete the upgrade. The updates have already been made on several linux machines. The linux computers in WWH624 are available for testing the updates. We urge people to test any packages that are critical to their work and let us know if they encounter any problems before the updates are done. The test machines are:
- WWH624: pubbox3.cims.nyu.edu (i686)
- WWH624: pubbox22.cims.nyu.edu (i686)
- WWH624: pubbox20.cims.nyu.edu (x86_64)
- WWH624: pubbox23.cims.nyu.edu (x86_64)
Some significant linux updates include (but are not limitted to):
- Linux Kernel (Automatic REBOOT)
Several packages have already been updated on solaris and linux machines. A full list of all software updates for linux and solaris is available on the update page.
Note: Solaris machines will not be rebooted.
Lab machines from the WWH 5th floor (502 and 512) will be moving to the 4th floor this week due to the coming construction on the 5th floor.
