   LATEST NEWS:


PLANNED NETWORK OUTAGE: Tuesday, August 26 - (7pm-3am maintenance window)

August 14, 2014

NSIT/ITS will be upgrading the network switches at Hinds on the 26th. There will be connection interruptions at that time, but each switch upgrade is expected to last less than an hour. Please be prepared to expect NFS connections to hang, and SSH and IMAP session disconnections. All services should resume by the end of the maintenance window.


NEW MAIL SERVER!

May 3, 2014

We're up and running on our new JFI email server! Send us any questions or comments, as sometimes we will not notice bugs if no one tells us.


ALERT - MAIL SERVER DOWNTIME:

April 14, 2014

On Saturday, May 3rd, the JFI mail server will be down for an extended period of time in order to move to a new replacement server. Linux desktops which mount the JFI mail server over NFS will need to be rebooted afterward; other machines will simply need to restart their email programs (e.g. Thunderbird). No mail will be lost during this transition, as we have a secondary mail server that messages will be diverted to during the downtime. We thank IT Services (NSIT) for their assistance in this transition.


JIN WANG WINS COMPUTE SERVER NAMING CONTEST:

May 2, 2011

Jin Wang has won our contest to name a new 48-core JFI/MRSEC computational server, which he has named superabacus.uchicago.edu. See our winner's page and preliminary information SGE documentation for new users here. Sorry about the time this news page has gone un-updated -- it has been a very busy year.


NAGEL GROUP ACQUIRES
NEW COMPUTATIONAL SERVER:

August 24, 2010

Prof. Sid Nagel's physics group has recently acquired a computational server taking advantage of the recent availability of advanced processor chips from AMD with 12 cores per chip, having a total of 24 cores on the system for simulations in Fortran code.


BACKUP SERVICES UPGRADE COMPLETED:

August 24, 2010

After moving many terabytes of archived backup data around between volumes, our new 43-terabyte system is finally fully settled into its daily usage pattern. (Actually, many of the more important backups have been running daily for some time now during the upgrades.) Feel free to use the backups whenever you need them.


DRUPAL WEB PORTALS
NOW AVAILABLE:

May 2, 2010

The JFI web server now offers Drupal sites to anyone affiliated with the institute who is interested in hosting one. Also, we are setting up test/development sites for helping you to migrate to Drupal, which are separate from your main current web space. (These test sites are protected from search engines and off-campus access.) Let us know if you want Drupal!


NEW HEAD NODE
FOR FREED GROUP
COMPUTATIONAL CLUSTER:

April 22, 2010

Prof. Karl Freed's chemistry research group has just purchased a new head node for their computational cluster, godzilla. The new system has six terabytes of storage and will help relieve performance bottlenecks that have been related to poor NFS performance. It will also be part of an upcoming migration plan to move the cluster entirely over to 64-bit. More to come as we setup and install the new machine...
