On Saturday, December 10, 2011, around 11 pm,  we will shut down the server that hosts faculty, staff and CS PhD student home directories to apply an urgent OS patch.  The patching and rebooting process should take about 60-90 minutes.  We will update this page as need if it will take appreciably longer.

Linux upgrades continue on the server front.  On Monday (11/07/2011), we expect to take the following servers offline while they are upgraded to Red Hat Enterprise Linux 6 (RHEL6):  

• Euler Cluster (euler01-05.cims.nyu.edu)

The hosts will be offline starting at 1:00 P.M. and expected to be offline possibly till the next day.

We urge users to test any packages that are critical to their work and let us know if they encounter any problems as early as possible.  All the other general Linux compute nodes have already been upgraded.

In the event that your software doesn't run on the RHEL6 platform, we have temporarily set up some RHEL5 systems as general compute servers (but let us know so we can help migrate it to RHEL6):

• stratus-1-11.cims.nyu.edu
• stratus-2-11.cims.nyu.edu
• stratus-3-11.cims.nyu.edu
• stratus-4-11.cims.nyu.edu
• stratus-5-11.cims.nyu.edu

The upgrades are part of a four phase process that started several weeks ago.  The current state of each phase is listed below:

• Phase 1 [COMPLETE] - Partial lab roll out and new servers
• Phase 2 [COMPLETE] - Remainder lab roll out and unattended desktops
• Phase 3 [COMPLETE] - Remainder desktop machines
• Phase 4 [INPROCESS] - Compute servers

See our compute servers page for a list of all available compute servers.

Please contact helpdesk@cims.nyu.edu with any questions.

Server Problems, September 28, 2011

Early this morning we have been experiencing problems with communication to one of our primary servers. Services are being restored, though we continue to see residual problems. We will continue working through the problems until things are back to normal. Thanks for your patience.

Linux upgrades continue on the server front.  On Thursday (9/15/2011), we expect to take the following servers offline while they are upgraded to Red Hat Enterprise Linux 6 (RHEL6):

•   Energons (energon[1-4].cims.nyu.edu)
•   crunchy3.cims.nyu.edu
•   mauler.cims.nyu.edu
•   brawler.cims.nyu.edu

Upgrades are expect to last the majority of the afternoon into the evening starting at 3:00 P.M.

We urge people to test any packages that are critical to their work and let us know if they encounter any problems as early as possible.  The following hosts have already been upgraded to RHEL6 and are available as compute nodes:

• crunchy4.cims.nyu.edu
• opencl1.cims.nyu.edu
• opencl2.cims.nyu.edu
• cuda1.cims.nyu.edu
• cuda2.cims.nyu.edu
• cuda3.cims.nyu.edu
• cuda4.cims.nyu.edu

Security and software updates are being pushed out to the CIMS Linux machines.  Compute nodes as well as desktop machines WILL BE REBOOTED this Thursday (September 15th, 2011) (to avoid a reboot notify helpdesk@cims.nyu.edu and reschedule a time) in the wee hours of the night between 10pm and 5am to complete software updates. In an effort to try and minimize any corrupted files or lost work, please save all your data and logout of any linux systems when you leave for the night. The updates have already been made on several linux machines in the computer lab located in WWH229. 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 occur. The machines that have been updated are:

• WWH229: pubbox1.cims.nyu.edu
  WWH229: pubbox10.cims.nyu.edu
  WWH229: pubbox16.cims.nyu.edu
  WWH229: pubbox26.cims.nyu.edu
  WWH229: pubbox33.cims.nyu.edu
  WWH229: pubbox34.cims.nyu.edu
  WWH229: pubbox41.cims.nyu.edu
  WWH229: pubbox45.cims.nyu.edu
  WWH229: pubbox46.cims.nyu.edu

Some significant software updates include (but are not limitted to):

• Linux kernel (automatic REBOOT)
• R
  boost

A full list of all software updates for linux and solaris is available on the update page.

Wednesday, February 16, 2011

This afternoon, between 2 and 3 pm, services were disrupted when one of our primary user fileservers crashed and rebooted. Some residual problems followed, including delays in mail delivery and communication problems on access2.cims.nyu.edu, which necessitated a reboot of that system.

Friday, January 21,  2011

On Friday, January 21, 2011,  beginning around 9 pm,  there will be a planned Cogen transfer related power outage that will disrupt CIMS computing services, including mail,  Courant and departmental webservers, access to home and data directories, and remote access to systems for 2-3 hours, during which time we will also perform regular updates to file and compute servers.  Please plan accordingly.

Tuesday, January 18, 2011

On Tuesday, January 18, 2011,  beginning around 11 pm,  CIMS linux desktop machines will be updated and rebooted. Please save all work prior to the updates.

We are currently experiencing service disruptions due to communication problems between servers.  We hope to have everything back to normal by around 5:30PM.

A Linux security update will be applied to all the Linux computers
(compute Servers as well as desktops) on Sunday night (October 3rd).
  
The Linux computers *WILL BE REBOOTED* as part of the process.  Downtime
for compute servers is expected to be from 11pm-1am.  Rolling desktop
reboots are expected to occur between the hours of 1am and 5am.
