Adapting LIGO workflows to run in the Open Science Grid
Edgar Fajardo, Frank Wuerthwein, Brian Bockelman +5
During the first observation run the LIGO collaboration needed to offload some of its most, intense CPU workflows from its dedicated computing sites to opportunistic resources. Ope…
Third-party transfers in WLCG using HTTP
Brian Bockelman, Andrea Ceccanti, Fabrizio Furano +3
Since its earliest days, the Worldwide LHC Computational Grid (WLCG) has relied on GridFTP to transfer data between sites. The announcement that Globus is dropping support of its o…
Towards an Intelligent Data Delivery Service
Wen Guan, Tadashi Maeno, Gancho Dimitrov +4
The ATLAS Event Streaming Service (ESS) at the LHC is an approach to preprocess and deliver data for Event Service (ES) that has implemented a fine-grained approach for ATLAS event…
Creating a content delivery network for general science on the internet backbone using XCaches
Edgar Fajardo, Marian Zvada, Derek Weitzel +9
A general problem faced by computing on the grid for opportunistic users is that delivering cycles is simpler than delivering data to those cycles. In this project we show how we i…
Exploring Erasure Coding Techniques for High Availability of Intermediate Data
Zhe Zhang, Brian Bockelman, Derek Weitzel +1
Scientific computing workflows generate enormous distributed data that is short-lived, yet critical for job completion time. This class of data is called intermediate data. A commo…
Trua: Efficient Task Replication for Flexible User-defined Availability in Scientific Grids
Zhe Zhang, Brian Bockelman, Derek Weitzel +3
Failure is inevitable in scientific computing. As scientific applications and facilities increase their scales over the last decades, finding the root cause of a failure can be ver…
