Dont forget to register! - All Hands Meeting 2016

Dont miss your opportunity to register for the All Hands Meeting of the Open Science Grid hosted by the Cyberinfrastructure Technology Integration group (CITI - of Clemson University, March 14-18, 2016. 

Register now at

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.
