Agentic HDF5's new file I/O telemetry system - Matt Larson on Call the Doctor 4/14/26

Matt Larson of The HDF Group will host Call the Doctor on Tuesday, April 14th. He will talk about recent developments in Agentic HDF5, specifically the new file I/O telemetry system and how that will help users optimize file access through an agent interface.

Today I Learned:

  • Bridging the Expertise Gap: Agentic HDF5 acts as an intelligent intermediary, allowing scientists to leverage advanced HDF5 features (like SWMR and Virtual Datasets) without needing to become library experts.
  • Proactive Telemetry: A new logging system records file access patterns, tool usage, and timing to create a performance profile for every session.
  • Anti-Pattern Detection: The agent can programmatically detect inefficiencies—such as redundant reads from the same chunks or suboptimal chunk sizes—that users might otherwise overlook.
  • Automated Advisories: Rather than waiting for a user to ask, the agent proactively suggests improvements like batching writes or re-chunking files to enhance speed and reduce overhead.
