40. GlideinWMS Improvements and Challenges

Marco Mambelli (Fermilab), Namratha Urs (Fermi National Accelerator Laboratory)

6/11/26, 1:30 PM

GlideinWMS is a workload management and resource provisioning system widely used for distributed scientific computing. Recent development efforts have focused on simplifying token-based authentication which is finally starting to be adopted in production and improving support for High Performance Computing (HPC) resources. This presentation will highlight recent progress in these areas and...

42. Auto-regulating input files that save time when jobs fail

Benjamin FitzGerald (University of Wisconsin-Madison)

I use CHTC and OSPool to run a rainfall frequency analysis pipeline across 200+ watersheds as part of FEMA's National Flood Insurance Program work. DAGMan was essential for automating job submission and output processing at this scale, but managing pipeline failures proved challenging -- specifically, ensuring that every daily precipitation file was properly analyzed before downstream steps...

58. Wrangling Massive Task Graphs with VineReduce

Douglas Thain (University of Notre Dame)

6/11/26, 2:15 PM

A number of modern programming frameworks encourage end users to write concurrent functional programs that are expanded into task graphs, and then executed using local parallelism. While providing an elegant user experience, these systems struggle when presented with large programs that generate million-node graphs and must run on heterogeneous systems. We demonstrate a new framework,...
