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…
Enabling Microsoft OneDrive Integration with HTCondor
Derek Weitzel
Accessing data from distributed computing is essential in many workflows, but can be complicated for users of cyberinfrastructure. They must perform multiple steps to make data ava…
SciTokens: Demonstrating Capability-Based Access to Remote Scientific Data using HTCondor
Alex Withers, Brian Bockelman, Derek Weitzel +7
The management of security credentials (e.g., passwords, secret keys) for computational science workflows is a burden for scientists and information security officers. Problems wit…
StashCache: A Distributed Caching Federation for the Open Science Grid
Derek Weitzel, Marian Zvada, Ilija Vukotic +6
Data distribution for opportunistic users is challenging as they neither own the computing resources they are using or any nearby storage. Users are motivated to use opportunistic…
