Last week, Open Science Grid held its annual All Hands Meeting, this time hosted by University of Utah. It was a pleasure to meet Pegasus users and see their talks. A big thank you to those projects and presenters, for sharing their experiences and continued use of Pegasus. Here are some highlights:

• VERITAS – “VERITAS and Its computational challenges”, presented by Udara Abeysekara, University of Utah. [slides]
• XENON1T – “XENON1T Computing on OSG – An Update”, presented by Benedikt Reidel, University of Chicago. [slides]
• Daniel Katz, California State University, Northridge. “Rudin-Shapiro-Like Sequences with Low Correlation” [slides]
• Ariella Gladstein, University of Arizona. “Inference of Evolutionary History with Approximate Bayesian Computation” [slides]
• Alex Feltus, Clemson University. “Mining Huge Collections of Genomics Datasets for Genes Controlling Complex Traits from Humans to Legumes” [slides]

The All Hands meeting also covered some technologies which either are supported in Pegasus and/or are of interest to the Pegasus community. For example:

• StashCache [slides] – A very efficient way to get data to your OSG jobs. Pegasus already has support for StashCache using stash:// URLs.
• HostedCE. “Expanding the Reach and Scope of Hosted CEs” [slides]. This enables you to access XSEDE allocations from the managed OSG infrastructure and provides an easy approach to run high throughput workloads across XSEDE machines.
