Several high-performance computational and storage resources will
be unavailable between Monday, October 12, and Monday, October 19,
as they are relocated from Wrubel Computing Center to the new IU
Data Center.
Systems affected by the move include:
* Big Red cluster
* Quarry cluster
* Data Capacitor and DC-WAN storage systems
* GPFS storage system
* Mason Cell cluster
Due to the number of ongoing enhancements and additions to Data
Center infrastructure, this timeline may require adjustment.
Timeline adjustments and milestones during the move will be posted
as they are available at
http://itnotices.iu.edu.
If you need special accommodations before, during, or after the
relocation process, please contact the UITS High-Performance Systems
group at: hps-admin@iu.edu

"Indiana University's Advanced Cyberinfrastructure: The Least You
Need To Know" has been revised for the new academic year. The
purpose of this document is to indicate what IU's facilities make
possible, to discuss how to use them and to introduce the
professional staff available to work with you. It is available at
http://pti.iu.edu/cyberinfrastructure.pdf -
MDSS and RFS will be changed to authenticate with the ADS.IU.EDU
Kerberos realm by September 14th, 2009, due to changes to the IU
authentication infrastructure. This change is described at
http://uits.iu.edu/page/ayjn
The following methods of access to these systems are *NOT*
affected by this change:
- Using cifs, such as with a Windows drive mapped to
\\rfs.iu.edu or \\smb.mdss.iu.edu
- Via the web interface at https://rfs.iu.edu or
https://www.mdss.iu.edu
- With ssh file transfer clients such as sftp to rfs.iu.edu or
to sftp.mdss.iu.edu.
- TeraGrid GridFTP transfers.
However, users of other access methods MUST make configuration
changes in order to continue connecting after the switchover.
These other methods include the native AFS client, FTP, and hsi.
The changes must me made before September 14th, 2009. The required
changes include updating keytabs, kerberos configuration and hsi
clients. Instructions can be found at
http://storage.iu.edu/adsmigrate.shtml -
TeraGrid resources are available, but you must submit a request for
computing time or data storage space. The allocations process has
been slightly revised -- the Development allocations have been
replaced by Startup and Education allocations, which are larger
than in the past, and explicitly support instruction.
Researchers may request Startup or Education allocations at any
time. These are treated as routine and processed immediately.
These allocations give you access to some of the most advanced
hardware in the world.
Large allocations require a proposal, and are handled by the
TeraGrid Resource Allocations Committee, which meets quarterly.
The next submission window is September 15 - October 15, for
allocations commencing January 1.
Information on getting started with the Teragrid is available at
http://pti.iu.edu/hpa/teragrid-support -
Data Services Day is dedicated to increasing awareness of the impact
and advantages of databases and data management in research. You
will have chance to talk with Oracle representatives, who will be
discussing functionality related data analysis and access. UITS
Research Technologies staff will present a general overview of
databases as applied to research and the services IU offers to
support the research community. And you also will hear stories from
IU researchers on how they currently use some of these products and
services to support their research.
Breakfast and lunch will be provided. This event is free, but you
must register to attend.
- When: Tuesday, September 15, 8:30 AM - 5:00 PM
(continental breakfast opens at 7:30 a.m.)
- Where: University Place Conference Center on the IUPUI campus
Talks presented during the Data Services Day general sessions will
be webcast from the workshop web pages. For more information or to
register for the event, please visit

Bioinformatics is the science of managing, mining, and extracting
knowledge from biological sequences and structures. The goal of
this Workshop is to present the latest research in high-performance
computing applied to bioinformatics.
The Parallel Bio-Computing Workshop will be held in conjunction
with the Seventh International Conference on Parallel Processing
and Applied Mathematics (PPAM 2009) in Wroclaw (Breslau), Poland,
September 13-16, 2009.

* Lunch time with SysAdmins - Talk to the experts!
You're invited to stop by and visit with the system administrators
who run IU's supercomputers, Big Red and Quarry, two of the most
powerful supercomputers in the world. Ask questions, share ideas,
or just chat in an informal setting. This is an opportunity for
you to learn how these centralized research computing resources
can help support your work. The location changes each month.
- When: September 14
- Where: Lobby, Informatics East

* Research Technologies Round Table
- Fall Update
Research Technologies (RT) maintains some of the most powerful
supercomputers in the world, as part of a comprehensive strategy
which includes computers, data storage systems, data collections,
instrument and sensor networks, and technical support.
As we head into fall, we'll take an updated look at Research
Technologies' compute systems which include the Big Red and Quarry
supercomputers, High Performance Storage Services, the Data
Capacitor, the Quarry Gateway Hosting Service and the TeraGrid.
For those of you new to IU, we'll have a general overview of these
resources, how to access them, simple examples of common usage
patterns, and an inventory of available support services.
Following the overview we'll discuss the changes that occurred over
the summer and those that are planned for the coming months,
specifically the equipment move into the new IU Data Center coming
up in October. System administrators will provide information on
what you need to do now in order to minimize the disruption of your
research activities during the week-long outage.
When: Wednesday, September 23rd, 12:30-1:30pm

* Data center maintenance, outage Sept. 10
Most UITS services will be unavailable 4-5AM on Thursday, Sept 11,
due to scheduled maintenance of the IU Bloomington data center.
This will affect services that require Network ID authentication
such as the Massive Data Storage Service, email, TIME, Oncourse,
and OneStart. IU Web services (IU campus web pages, MySQL, Mypage,
the Knowledge Base, and streaming media, among others) will also be
unavailable. Only ssh key based and certificate based authentication
to Big Red or Quarry will work for new connections during that
interval, but existing sessions would be unaffected.
For a complete list of affected services, see:
http://itnotices.iu.edu/notice.aspx?id=13302
----------
The maintenance window for Big Red and Quarry is the first Tuesday
of each month, 7am - 7pm EDT.
The maintenance window for the Mass Store and Research File System
is every Sunday 7-10AM.
Outage reports are available online at:

If you have questions pertaining to IU's cyberinfrastructure, or
you are encountering some difficulty, there are several ways to
obtain help.
The IU Knowledge Base (http://kb.iu.edu) is an excellent source of
help on how to do things.
An introduction and overview titled "Indiana University's
CyberInfrastructure: The least you need to know" is available at
http://pti.iu.edu/cyberinfrastructure.pdf
If you have problems which the KB does not enable you to solve,
questions about system outages, or if you just have a problem and
you don't know who to contact, send email to
