All nodes and GPFS filesystem issues affected from the power failure should be resolved as of late Friday evening (June 16) . If you are still experiencing problems, please let us know at pace-support@oit.gatech.edu.

Large Scale Problem

Posted by on Wednesday, 7 June, 2017

Update (6/7/2017, 1:20pm): The network issues are now addressed and systems are back in normal operation.Please check your jobs and resubmit failed jobs as needed. If you continue to experience any problems, or need our assistance for anything else, please contact us at pace-support@oit.gatech.edu. We are sorry for this inconvenience and thank you once again for your patience.

Original message: We are experiencing a large scale network problem impacting multiple storage servers and software repository with a potential impact on running jobs. We are currently actively working to get it resolved and will provide updates as much as possible.

College of Engineering (COE) license servers available starting 5:10 pm yesterday

Posted by on Wednesday, 12 April, 2017

Starting 5:10 pm 11 April 2017, COE license servers are available again.

Multiple Georgia power outages are plaguing multiple license servers on campus. All efforts have been made to keep systems available. If your jobs report missing or unavailable licenses, please check http://licensewatcher.ecs.gatech.edu/ for the most up to date information.

College of Engineering license servers going dark at 3:35 pm

Posted by on Tuesday, 11 April, 2017

College of Engineering (COE) license servers will go dark at 3:35pm. Research and Instruction to be impacted.

COE system engineers have stated: Running out of UPS run time. Ansys / Comsol / Abaqus / Solidworks and other software will go dark. Matlab / Autocad and NX should still be up (running in a different location).

UPS Power System Repair

Posted by on Wednesday, 1 February, 2017

PACE and other systems in the Rich 133 computer room experienced a brief power event on the afternoon of Monday, January 30th. This power event involved significant failure of one of the three uninterruptible power supply (UPS) systems that supply the Rich computer room with stable, filtered power. The UPS system switched over to bypass mode as designed and one of the main power feeder transfer switches also experienced a failure. Stable power continued to the PACE systems and all systems and network devices continued to operate without interruption.

Repair of the failed UPS is underway but parts may not be available for up to two weeks. During this time, the UPS power system will remain in bypass mode connecting many of the PACE systems to standard campus power. Our experience shows the campus power is usually clean enough to operate normally and so we are operating normally. Repair and re-testing of the UPS can take place without interruption of the existing power. We will announce this repair transition when we have additional information.

Should there be any significant campus power interruption during this interim time, we may lose power to some of the PACE systems. Rest assured the PACE staff will do our best to recover all systems affected by such an event. We will keep you informed via blog and announcement mailing lists of the repair progress.

Headnode GPFS Problem

Posted by on Friday, 30 September, 2016

About 8:30pm this evening, one of the PACE systems that provides services to the GPFS files to headnodes and other PACE internal systems failed. When this happens, users may see the message “stale file handle” or you may notice there are no files under the /gpfs directory. This is a temporary condition that should be fixed shortly.

Please note: All files that were already written and all files accessed or written by any compute node are unaffected. However, if you were in the process of editing a file on a headnode, only your most recent changes may be unavoidably lost. In addition, any process you may have had running on a headnode system using these files may have been killed due to this failure.

To prevent this from recurring, PACE had ordered and very recently received a new computer to replace the system that failed this evening. Our staff will undertake the testing and replacement as soon as possible and we will post an announcement here once the new system is in service.

We apologize for this inconvenience and thank those users who let us know quickly.

International HPC Summer School 2015

Posted by on Thursday, 5 March, 2015

Graduate students and postdoctoral scholars from institutions in Canada, Europe, Japan and the United States are invited to apply for the sixth International Summer School on HPC Challenges in Computational Sciences, to be held June 21-26, 2015, in Toronto, Canada. Applications are due March 11, 2015. The summer school is sponsored by Compute/Calcul Canada, the Extreme Science and Engineering Discovery Environment (XSEDE) with funds from the U.S. National Science Foundation, the Partnership for Advanced Computing in Europe (PRACE) and the RIKEN Advanced Institute for Computational Science (RIKEN AICS).

Leading Canadian, European, Japanese and American computational scientists and HPC technologists will offer instruction on a variety of topics, including:

HPC challenges by discipline (e.g, earth, life and materials sciences, physics)
HPC Programming Proficiencies
Performance analysis and profiling
Algorithmic approaches and numerical libraries
Data-intensive computing
Scientific visualization
Canadian, EU, Japanese and U.S. HPC-infrastructures

The expense-paid program will benefit advanced scholars from Canadian, European, Japanese and U.S. institutions who use HPC to conduct research. Interested students should apply by March 11, 2015. Meals, housing, and travel will be covered for the selected participants. Applications from graduate students and postdocs in all science and engineering fields are welcome. Preference will be given to applicants with parallel programming experience, and a research plan that will benefit from the utilization of high performance computing systems.
