Active System Maintenance Reports
- May 2015 Scheduled Downtime - Pacman, Fish, Linux Workstations, Big Dipper, lsi
Planned System Outage for the Annual Butrovich Computer Facility Fire Alarm and Safety Test
Start Time: 9pm on Saturday May 16, 2015
End Time: 9pm on Sunday May 17, 2015
Systems Affected: Pacman, Fish, Bigdipper, Linux VMs, LSI Portals
Reason: The annual Butrovich Computer Facility Fire Alarm and Safety Test will be held the third weekend in May 2015. This event is an effort to promote facility preventive maintenance and will result in the computing systems located in the Butrovich Computer Facility to be powered down. All ARSC systems will be taken offline and powered down starting Saturday May 16th and ending Sunday May 17th if all goes as planned.
User jobs submitted to the pacman and fish HPC clusters as well as the LSI bioinformatics portal will remain queued on the systems and will launch after power is restored to the systems and the systems are brought back online and tested.
Important Announcement Regarding the HRRR-AK Model
Apologies for the short notice, but the HRRR-AK model behind weather.arsc.edu will be temporarily suspended on Friday, 10 April 2015 in order to transition from the current, energy-inefficient computing platform to a newer system. With this transition - which is expected to be complete by early summer - the HRRR-AK will be upgraded to newer versions of WRF and HRRR-specific routines, and new features are planned for incorporation.
Additionally, older, archived data will be removed, some of which dates back to 2010. This will likely take place in the next month. At this point, all raw NetCDF wrfout outputs that date earlier than 6 months ago will be removed. A sliding 6-month archive window will be maintained. Each forecast generates close to 400 GBytes of these wrfout files. By removing these old files we anticipate freeing capacity to store more useful products in the future.
During this hiatus, we encourage you to provide us with thoughts and ideas how a revived HRRR-AK may better serve the needs of a Weather-Ready Alaska, providing forecasts and warnings for the protection of life and property and enhancement of the economy. Please think about things like frequency and duration of forecasts, types of forecast and verification products, etc. Some found our high-resolution HYSPLIT-ready output products to be useful. Are these kinds of things worth considering? We have put some thought into an optional, floating 1km nest (analogous to the 1km NAM NEST for fire weather) - what about this? Most importantly, are there potential features to an enhanced HRRR-AK that we might be able to support through outside collaborations?
Please share your thoughts with Dr. Don Morton <email@example.com>.
2015 Computational Chemistry Workshops
July 14-16 and July 21-23, 2015
The Arctic Region Supercomputing Center in conjunction with the UAF Department of Chemistry and Biochemistry are pleased to announce workshops in Computational Chemistry for the weeks of July 14-16, 2015 and July 21-23, 2015 .

2015 Spring Training begins February 6th!
The ARSC Spring Training schedule is now available! Learn about the Linux Command Line, Totalview Debugger, GIT Repository, Ruby on Rails, how to optimize your use of HPC batch schedulers, or how to edit research footage using Adobe Premier Pro: www.arsc.edu/support/training/index.xml
Training is held on Fridays in WRRB 009 and is open to all UAF Faculty, Staff, and Students. No registration is required!

EPSCoR Award Funds Two ARSC Web Sites
Part of the NSF Research Infrastructure Improvement Cyberconnectivity Award, administered by Alaska EPSCoR, funded two new ARSC Web sites. One of these sites is Alaska Data Central, which is designed to serve as a central access point for data and metadata from across the University of Alaska system. The other is Scholarworks, an institutional repository holding UA library materials, theses and dissertations, meeting minutes, scientific posters, and archival footage and images.
If your research involves the use of ARSC resources, remember to mention ARSC in your publications acknowledgments! We recommend a statement similar to, "This work was supported in part by a grant of HPC resources from the Arctic Region Supercomputing Center and the University of Alaska Fairbanks".
Information about how to incorporate ARSC utilization into grant proposals is available in the ARSC knowledge base.
