OSG All Hands Meeting 2016 - Registration Open

OSG All Hands Meeting 2016 - Clemson University

Registration for the All Hands Meeting of the Open Science Grid hosted
by the Cyberinfrastructure Technology Integration group (CITI -
http://citi.clemson.edu/) of Clemson University, March 14-18, 2016,
Clemson, South Carolina is now open at http://citi.clemson.edu/osg-ahm-2016/index.html

Topics to be discussed will include:

* How high-throughput computing accelerates research, and how OSG can help users scale up.

* Usability challenges and solutions for distributed high-throughput computing applications.

* Connecting virtual organizations, campus researchers and XSEDE users
to the OSG: command line, science gateways, and workflow frameworks.

* Training and education: partnerships with ACI-REF and Software Carpentry.

* Serving more of the "long tail" of science with high-throughput
parallel computing: incorporating multi-core, GPU and virtual cluster
resources into science workflows using shared and allocated
distributed infrastructure.

* Broadening participation and use of OSG from various disciplines,
strategy for expanding use, potential areas of impact.

* Advanced network analytics services for national Science DMZ infrastructure.

* Cyberinfrastructure partnerships: university research computing HPC
centers, XSEDE XD providers, DOE laboratories, NSF Large Facility
computing organizations and commercial cloud providers. Technologies,
strategies, ideas, and discussions on how OSG can foster partnerships
across the widest possible range of CI.

The program this year has been expanded to include hands-on workshops
for advanced cyberinfrastructure providers and scientific user
communities accessing the shared resources connected by the OSG. As
has been the custom, the 2016 OSG AHM will be co-located with the U.S.
Large Hadron Collider (LHC at CERN) computing facility meetings.

Logistical information, registration and agenda are available at http://citi.clemson.edu/osg-ahm-2016/index.html

OSG Release Series 3.2 Deprecation - End of Life August 2016

The OSG 3.3 release series began on 11 August 2015, and thus will reach its 6-month anniversary with the February release of OSG 3.3.9. According to our release series support policy [*], OSG 3.2 is the “previous release series” and will begin its 6-month deprecation phase. Therefore, after the February release, OSG 3.2 will receive only critical bug and security patches. [*] https://twiki.opensciencegrid.org/bin/view/SoftwareTeam/ReleaseSeriesSupportPolicy Because of the change in OSG 3.2’s status, OSG urges site administrators to update to OSG 3.3 if they have not done so already. Looking forward, the end-of-life date for OSG 3.2 is scheduled for 9 August 2016. If you have questions or comments about this announcement, the OSG release series, how to update your site, or so on, please email us at the usual OSG support address: goc@opensciencegrid.org
