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.

Georgia Tech taking next step to expand Tech Square presence

Posted by on Wednesday, 21 January, 2015

The Georgia Institute of Technology has taken another step to reinforce its commitment to support and enhance the Institute’s innovation ecosystem and economic development role in Midtown Atlanta’s Technology Square. The Institute, advised by Cushman & Wakefield, issued a request for qualification (RFQ) for private developers interested in the expansion of Technology Square.

Anchored by a high performance computing center, the development will be a transformative project providing a sustainable platform for expanding interdisciplinary research, collaboration and co-location with industry partners, while also supporting Georgia Tech’s academic and research programs in advanced analytics and computing.

Free Supercomputing in Plain English Workshop, Spring 2015

Posted by on Monday, 3 November, 2014

Free Supercomputing in Plain English (SiPE)
Available live in person and live via videoconferencing

These workshops focus on fundamental issues of High Performance
Computing (HPC) as they relate to Computational and Data-enabled
Science & Engineering (CDS&E), including:

* overview of HPC;
* the storage hierarchy;
* instruction-level parallelism;
* high performance compilers;
* shared memory parallelism (e.g., OpenMP);
* distributed parallelism (e.g., MPI);
* HPC application types and parallel paradigms;
* multicore optimization;
* high throughput computing;
* accelerator computing (e.g., GPUs);
* scientific and I/O libraries;
* scientific visualization.

Tuesdays starting Jan 20 2015, 1:30pm Central Time
(3:30pm Atlantic, 2:30pm Eastern, 12:30pm Mountain, 11:30am Pacific)

Live in person: Stephenson Research & Technology Center boardroom,
University of Oklahoma Norman campus

Live via videoconferencing: details to be announced

Registration coming soon!

So far, the SiPE workshops have reached over 1500 people at
248 institutions, agencies, companies and organizations in
47 US states and territories and 10 other countries:

* 178 academic institutions;
* 29 government agencies;
* 26 private companies;
* 15 not-for-profit organizations.

SiPE is targeted at an audience of not only computer scientists
but especially scientists and engineers, including a mixture of
undergraduates, graduate students, faculty and staff.

The key philosophy of the SiPE workshops is that an HPC-based code
should be maintainable, extensible and, most especially, portable
across platforms, and should be sufficiently flexible that it can
adapt to, and adopt, emerging HPC paradigms.

1 semester of programming experience and/or coursework in any of
Fortan, C, C++ or Java, recently
