Annual Project Renewals
It's that time of year again: Principal investigators for ARSC projects are asked to submit plans for resource utilization for the upcoming year, which begins October 1, 2013.
All PIs should have received email from email@example.com with detailson how to access the ARSC Extranet to complete the renewal process. These renewals are helpful to plan resource needs for the upcoming year, and they are also helpful with ARSC's reporting to UAF. Thanks to PIs for renewing in a timely manner.
New User Support Request Form
ARSC has a new way to get in touch. This new user support request form helps to gather necessary information to provide a rapid resolution to an inquiry. The form is available here, via the main ARSC homepage at www.arsc.edu:
You can also visit ARSC in person (Suite 105, West Ridge Research Building on the UAF campus) during business hours, email firstname.lastname@example.org, or call at 907-450-8602.

Are you interested in the FREE Oklahoma Supercomputing Symposium 2013 on Wed Oct 2 on the University of Oklahoma Norman campus?
Over the past decade, the Symposium has had over 2500 attendees from 101 academic institutions from 27 US states and territories, 119 private companies, 35 government agencies (federal, state, municipal, foreign) and 17 non-governmental organizations.

More Emacs: Writable Dired
Following up on our two-part series on emacs, Martin Luethi provided this additional information about emacs capabilities:
Writable Dired (WDired) mode.
In WDired mode, you can edit the names of the files in the buffer, the target of the links, and the permission bits of the files.
Type C-c C-c to exit WDired mode, returning to Dired mode, and make your edits "take effect" by modifying the file and directory names, link targets, and/or file permissions on disk. If you delete the filename of a file, it is flagged for deletion in the Dired buffer.
Type C-c ESC to abort your edits and exit WDired mode.
This is so incredibly useful, as search/replace and keyboard macros (another incredibly powerful Emacs capability) can be used to rename bunches of files, where the only alternative would be using a scripting language.
Quick-Tip Q & A
Last time, we asked:
Q: What are some of your favorite experiences on the first day of classes?
Via a reader:
A: I like seeing new students, with all their energies poised to learn a lot, and to make an impact.
Via a reader:
A: At UAF, it's a magical time of year. The flowers are still in full bloom, the streets and buildings are cleaned. If only there was a little less construction, and better parking, things would be perfect.
Here is a new question for next time:
Q: I noticed the ARSC Cray, called "fish," comes with NVIDIA general-purpose graphics processing units (GPUs). What has been the experience of ARSC users, in using GPUs?
The Arctic Region Supercomputing Center (ARSC) provides research and high performance computing, large-scale storage, and related services to the students, faculty and staff of the University of Alaska.
