Posted by on Friday, 24 July, 2020

Dear PACE Users,

RESOLVED: PACE is now ready for research.

We are preparing for our next PACE maintenance period, which will begin at 6:00 AM on August 6th, 2020 and conclude at 11:59 PM on August 8th, 2020. As usual, jobs with long walltimes will be held by the scheduler to ensure that no active jobs will be running when systems are powered off. These jobs will be released as soon as the maintenance activities are complete.

We are still finalizing planned activities for the maintenance period. Here is a current list:


– None Current.


– [Resolved] Coda Lustre Upgrade (This will start on Wednesday (08/05), which will impact testflight-coda only, and a scheduler reservation was put in place to prevent any jobs from running past 6:00AM on Wednesday – August 5).

– [Resolved] Install additional line cards for CS8500 Infiniband switch.

– [Resolved] Deploy PBSToools RPM on schedulers

OIT Network Maintenance 12/18/2019-12/19/2019

Posted by on Monday, 16 December, 2019

To Our Valued PACE Research Community,

We are writing to inform our research community of upcoming maintenance, as follows: 

The Office of Information Technology (OIT) will be performing a series of upgrades to the networking infrastructure to improve the performance and reliability of networking operations. Some of these upcoming enhancements may impact PACE users’ ability to connect and interact with computational and storage resources. We do not expect that this network maintenance to have any impact on currently running jobs.   

12/18/2019 20:00-23:59 (Router Code Upgrade) An upgrade to the software on some routers is scheduled and will include an approximate 30-minute disruption to telecommunication services.  

12/18/2019 20:00 – 12/19/2019 02:00 (Date Center Router Code Upgrade & Routing Engine Upgrade)  An upgrade to the software on multiple devices will impact network connectivity across the main campus of the Georgia Institute of Technology. This disruption will include the CODA Building. 

OIT Technical Teams will be actively monitoring the progress of upgrades during the maintenance windows described above. These teams will be providing ongoing communications to student, faculty, and staff members of the Institute. A central location for progress communications will be available at 

Issues during the upgrade may be reported to the OIT Network Operations Center at (404)894-4669. 

We do not expect any impact on running jobs and no changes to the PACE computational and storage resources are part of this OIT Network maintenance. 

Thank you for your time and diligence,

PACE Outreach and Faculty Interaction Team

OIT Planned Maintenance

Posted by on Wednesday, 25 September, 2019

The OIT Network Services team will be performing a software upgrade on our campus Carrier-Grade NAT (CGN) appliances this week – see OIT Status for a full description. The affected subnet is the out of band management of the Hive/MRI servers; additionally, only internet-bound connections are being serviced. As such, no failures are expected for users of the Hive/MRI servers. Nonetheless, if you encounter connectivity issues to Hive resources, please do not hesitate to contact for assistance.
